-Generic USB Device Properties
-
-Usually, we only use device tree for hard wired USB device.
-The reference binding doc is from:
-http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
-
-Four types of device-tree nodes are defined: "host-controller nodes"
-representing USB host controllers, "device nodes" representing USB devices,
-"interface nodes" representing USB interfaces and "combined nodes"
-representing simple USB devices.
-
-A combined node shall be used instead of a device node and an interface node
-for devices of class 0 or 9 (hub) with a single configuration and a single
-interface.
-
-A "hub node" is a combined node or an interface node that represents a USB
-hub.
-
-
-Required properties for device nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
- The textual representation of VID and PID shall be in lower case hexadecimal
- with leading zeroes suppressed. The other compatible strings from the above
- standard binding could also be used, but a device adhering to this binding
- may leave out all except for "usbVID,PID".
-- reg: the number of the USB hub port or the USB host-controller port to which
- this device is attached. The range is 1-255.
-
-
-Required properties for device nodes with interface nodes:
-- #address-cells: shall be 2
-- #size-cells: shall be 0
-
-
-Required properties for interface nodes:
-- compatible: "usbifVID,PID.configCN.IN", where VID is the vendor id, PID is
- the product id, CN is the configuration value and IN is the interface
- number. The textual representation of VID, PID, CN and IN shall be in lower
- case hexadecimal with leading zeroes suppressed. The other compatible
- strings from the above standard binding could also be used, but a device
- adhering to this binding may leave out all except for
- "usbifVID,PID.configCN.IN".
-- reg: the interface number and configuration value
-
-The configuration component is not included in the textual representation of
-an interface-node unit address for configuration 1.
-
-
-Required properties for combined nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
- The textual representation of VID and PID shall be in lower case hexadecimal
- with leading zeroes suppressed. The other compatible strings from the above

-
-Required properties for hub nodes with device nodes:
-- #address-cells: shall be 1
-- #size-cells: shall be 0
-
-
-Required properties for host-controller nodes with device nodes:
-- #address-cells: shall be 1

-Generic USB Device Properties
-
-Usually, we only use device tree for hard wired USB device.
-The reference binding doc is from:
-http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
-
-Four types of device-tree nodes are defined: "host-controller nodes"
-representing USB host controllers, "device nodes" representing USB devices,
-"interface nodes" representing USB interfaces and "combined nodes"
-representing simple USB devices.
-
-A combined node shall be used instead of a device node and an interface node
-for devices of class 0 or 9 (hub) with a single configuration and a single
-interface.
-
-A "hub node" is a combined node or an interface node that represents a USB
-hub.
-
-
-Required properties for device nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
- The textual representation of VID and PID shall be in lower case hexadecimal
- with leading zeroes suppressed. The other compatible strings from the above
- standard binding could also be used, but a device adhering to this binding
- may leave out all except for "usbVID,PID".
-- reg: the number of the USB hub port or the USB host-controller port to which
- this device is attached. The range is 1-255.
-
-
-Required properties for device nodes with interface nodes:
-- #address-cells: shall be 2
-- #size-cells: shall be 0
-
-
-Required properties for interface nodes:
-- compatible: "usbifVID,PID.configCN.IN", where VID is the vendor id, PID is
- the product id, CN is the configuration value and IN is the interface
- number. The textual representation of VID, PID, CN and IN shall be in lower
- case hexadecimal with leading zeroes suppressed. The other compatible
- strings from the above standard binding could also be used, but a device
- adhering to this binding may leave out all except for
- "usbifVID,PID.configCN.IN".
-- reg: the interface number and configuration value
-
-The configuration component is not included in the textual representation of
-an interface-node unit address for configuration 1.
-
-
-Required properties for combined nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
- The textual representation of VID and PID shall be in lower case hexadecimal
- with leading zeroes suppressed. The other compatible strings from the above
- standard binding could also be used, but a device adhering to this binding
- may leave out all except for "usbVID,PID".
-- reg: the number of the USB hub port or the USB host-controller port to which

-
-Required properties for hub nodes with device nodes:
-- #address-cells: shall be 1
-- #size-cells: shall be 0
-
-
-Required properties for host-controller nodes with device nodes:
-- #address-cells: shall be 1
-- #size-cells: shall be 0

-MediaTek XS-PHY binding
---------------------------
-
-The XS-PHY controller supports physical layer functionality for USB3.1
-GEN2 controller on MediaTek SoCs.
-
-Required properties (controller (parent) node):
- - compatible : should be "mediatek,<soc-model>-xsphy", "mediatek,xsphy",
- soc-model is the name of SoC, such as mt3611 etc;
- when using "mediatek,xsphy" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt3611-xsphy"
-
- - #address-cells, #size-cells : should use the same values as the root node
- - ranges: must be present
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple U3 ports,
- exclude port's private register, if only U2 ports provided,
- shouldn't use the property.
- - mediatek,src-ref-clk-mhz : u32, frequency of reference clock for slew rate
- calibrate
- - mediatek,src-coef : u32, coefficient for slew rate calibrate, depends on
- SoC process
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : must contain
- "ref": 48M reference clock for HighSpeed analog phy; and 26M
- reference clock for SuperSpeedPlus analog phy, sometimes is
- 24M, 25M or 27M, depended on platform.
-- #phy-cells : should be 1
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
-
-The following optional properties are only for debug or HQA test
-Optional properties (PHY_TYPE_USB2 port (child) node):
-- mediatek,eye-src : u32, the value of slew rate calibrate
-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
-- mediatek,efuse-intr : u32, the selection of Internal Resistor
-
-Optional properties (PHY_TYPE_USB3 port (child) node):
-- mediatek,efuse-intr : u32, the selection of Internal Resistor
-- mediatek,efuse-tx-imp : u32, the selection of TX Impedance
-- mediatek,efuse-rx-imp : u32, the selection of RX Impedance

-MediaTek XS-PHY binding
---------------------------
-
-The XS-PHY controller supports physical layer functionality for USB3.1
-GEN2 controller on MediaTek SoCs.
-
-Required properties (controller (parent) node):
- - compatible : should be "mediatek,<soc-model>-xsphy", "mediatek,xsphy",
- soc-model is the name of SoC, such as mt3611 etc;
- when using "mediatek,xsphy" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt3611-xsphy"
-
- - #address-cells, #size-cells : should use the same values as the root node
- - ranges: must be present
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple U3 ports,
- exclude port's private register, if only U2 ports provided,
- shouldn't use the property.
- - mediatek,src-ref-clk-mhz : u32, frequency of reference clock for slew rate
- calibrate
- - mediatek,src-coef : u32, coefficient for slew rate calibrate, depends on
- SoC process
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : must contain
- "ref": 48M reference clock for HighSpeed analog phy; and 26M
- reference clock for SuperSpeedPlus analog phy, sometimes is
- 24M, 25M or 27M, depended on platform.
-- #phy-cells : should be 1
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
-
-The following optional properties are only for debug or HQA test
-Optional properties (PHY_TYPE_USB2 port (child) node):
-- mediatek,eye-src : u32, the value of slew rate calibrate
-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
-- mediatek,efuse-intr : u32, the selection of Internal Resistor
-
-Optional properties (PHY_TYPE_USB3 port (child) node):
-- mediatek,efuse-intr : u32, the selection of Internal Resistor
-- mediatek,efuse-tx-imp : u32, the selection of TX Impedance
-- mediatek,efuse-rx-imp : u32, the selection of RX Impedance

-MediaTek XS-PHY binding
---------------------------
-
-The XS-PHY controller supports physical layer functionality for USB3.1
-GEN2 controller on MediaTek SoCs.
-
-Required properties (controller (parent) node):
- - compatible : should be "mediatek,<soc-model>-xsphy", "mediatek,xsphy",
- soc-model is the name of SoC, such as mt3611 etc;
- when using "mediatek,xsphy" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt3611-xsphy"
-
- - #address-cells, #size-cells : should use the same values as the root node
- - ranges: must be present
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple U3 ports,
- exclude port's private register, if only U2 ports provided,
- shouldn't use the property.
- - mediatek,src-ref-clk-mhz : u32, frequency of reference clock for slew rate
- calibrate
- - mediatek,src-coef : u32, coefficient for slew rate calibrate, depends on
- SoC process
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : must contain
- "ref": 48M reference clock for HighSpeed analog phy; and 26M
- reference clock for SuperSpeedPlus analog phy, sometimes is
- 24M, 25M or 27M, depended on platform.
-- #phy-cells : should be 1
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
-
-The following optional properties are only for debug or HQA test
-Optional properties (PHY_TYPE_USB2 port (child) node):
-- mediatek,eye-src : u32, the value of slew rate calibrate
-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage

-MediaTek T-PHY binding
---------------------------
-
-T-phy controller supports physical layer functionality for a number of
-controllers on MediaTek SoCs, such as, USB2.0, USB3.0, PCIe, and SATA.
-
-Required properties (controller (parent) node):
- - compatible : should be one of
- "mediatek,generic-tphy-v1"
- "mediatek,generic-tphy-v2"
- "mediatek,mt2701-u3phy" (deprecated)
- "mediatek,mt2712-u3phy" (deprecated)
- "mediatek,mt8173-u3phy";
- make use of "mediatek,generic-tphy-v1" on mt2701 instead and
- "mediatek,generic-tphy-v2" on mt2712 instead.
-
-- #address-cells: the number of cells used to represent physical
- base addresses.
-- #size-cells: the number of cells used to represent the size of an address.
-- ranges: the address mapping relationship to the parent, defined with
- - empty value: if optional 'reg' is used.
- - non-empty value: if optional 'reg' is not used. should set
- the child's base address to 0, the physical address
- within parent's address space, and the length of
- the address map.
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple ports,
- exclude port's private register. It is needed on mt2701
- and mt8173, but not on mt2712.
- - mediatek,src-ref-clk-mhz : frequency of reference clock for slew rate
- calibrate
- - mediatek,src-coef : coefficient for slew rate calibrate, depends on
- SoC process
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- #phy-cells : should be 1 (See second example)
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
- - PHY_TYPE_PCIE
- - PHY_TYPE_SATA
-
-Optional properties (PHY_TYPE_USB2 port (child) node):
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : may contain
- "ref": 48M reference clock for HighSpeed (digital) phy; and 26M
- reference clock for SuperSpeed (digital) phy, sometimes is
- 24M, 25M or 27M, depended on platform.
- "da_ref": the reference clock of analog phy, used if the clocks
- of analog and digital phys are separated, otherwise uses
- "ref" clock only if needed.
-
-- mediatek,eye-src : u32, the value of slew rate calibrate
-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
-- mediatek,bc12 : bool, enable BC12 of u2phy if support it
-- mediatek,discth : u32, the selection of disconnect threshold
-- mediatek,intr : u32, the selection of internal R (resistance)
-
-Example:
-
-u3phy: usb-phy@11290000 {
- compatible = "mediatek,mt8173-u3phy";
- reg = <0 0x11290000 0 0x800>;
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- u2port0: usb-phy@11290800 {
- reg = <0 0x11290800 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-
- u3port0: usb-phy@11290900 {
- reg = <0 0x11290800 0 0x700>;
- clocks = <&clk26m>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-
- u2port1: usb-phy@11291000 {
- reg = <0 0x11291000 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-};
-
-Specifying phy control of devices
----------------------------------
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type;
-phy-names for each port are optional.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
-usb30: usb@11270000 {
- ...
- phys = <&u2port0 PHY_TYPE_USB2>, <&u3port0 PHY_TYPE_USB3>;
- phy-names = "usb2-0", "usb3-0";
- ...
-};
-
-
-Layout differences of banks between mt8173/mt2701 and mt2712
--------------------------------------------------------------
-mt8173 and mt2701:
-port offset bank
-shared 0x0000 SPLLC
- 0x0100 FMREG
-u2 port0 0x0800 U2PHY_COM

-MediaTek T-PHY binding
---------------------------
-
-T-phy controller supports physical layer functionality for a number of
-controllers on MediaTek SoCs, such as, USB2.0, USB3.0, PCIe, and SATA.
-
-Required properties (controller (parent) node):
- - compatible : should be one of
- "mediatek,generic-tphy-v1"
- "mediatek,generic-tphy-v2"
- "mediatek,mt2701-u3phy" (deprecated)
- "mediatek,mt2712-u3phy" (deprecated)
- "mediatek,mt8173-u3phy";
- make use of "mediatek,generic-tphy-v1" on mt2701 instead and
- "mediatek,generic-tphy-v2" on mt2712 instead.
-
-- #address-cells: the number of cells used to represent physical
- base addresses.
-- #size-cells: the number of cells used to represent the size of an address.
-- ranges: the address mapping relationship to the parent, defined with
- - empty value: if optional 'reg' is used.
- - non-empty value: if optional 'reg' is not used. should set
- the child's base address to 0, the physical address
- within parent's address space, and the length of
- the address map.
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple ports,
- exclude port's private register. It is needed on mt2701
- and mt8173, but not on mt2712.
- - mediatek,src-ref-clk-mhz : frequency of reference clock for slew rate
- calibrate
- - mediatek,src-coef : coefficient for slew rate calibrate, depends on
- SoC process
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- #phy-cells : should be 1 (See second example)
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
- - PHY_TYPE_PCIE
- - PHY_TYPE_SATA
-
-Optional properties (PHY_TYPE_USB2 port (child) node):
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : may contain
- "ref": 48M reference clock for HighSpeed (digital) phy; and 26M
- reference clock for SuperSpeed (digital) phy, sometimes is
- 24M, 25M or 27M, depended on platform.
- "da_ref": the reference clock of analog phy, used if the clocks
- of analog and digital phys are separated, otherwise uses
- "ref" clock only if needed.
-
-- mediatek,eye-src : u32, the value of slew rate calibrate
-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
-- mediatek,bc12 : bool, enable BC12 of u2phy if support it
-- mediatek,discth : u32, the selection of disconnect threshold
-- mediatek,intr : u32, the selection of internal R (resistance)
-
-Example:
-
-u3phy: usb-phy@11290000 {
- compatible = "mediatek,mt8173-u3phy";
- reg = <0 0x11290000 0 0x800>;
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- u2port0: usb-phy@11290800 {

- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-};
-
-Specifying phy control of devices
----------------------------------
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type;
-phy-names for each port are optional.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
-usb30: usb@11270000 {
- ...
- phys = <&u2port0 PHY_TYPE_USB2>, <&u3port0 PHY_TYPE_USB3>;
- phy-names = "usb2-0", "usb3-0";
- ...
-};
-
-
-Layout differences of banks between mt8173/mt2701 and mt2712
--------------------------------------------------------------
-mt8173 and mt2701:
-port offset bank
-shared 0x0000 SPLLC
- 0x0100 FMREG
-u2 port0 0x0800 U2PHY_COM

-- mediatek,eye-vrt : u32, the selection of VRT reference voltage
-- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
-- mediatek,bc12 : bool, enable BC12 of u2phy if support it
-- mediatek,discth : u32, the selection of disconnect threshold
-- mediatek,intr : u32, the selection of internal R (resistance)
-
-Example:
-
-u3phy: usb-phy@11290000 {
- compatible = "mediatek,mt8173-u3phy";
- reg = <0 0x11290000 0 0x800>;
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- u2port0: usb-phy@11290800 {
- reg = <0 0x11290800 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-
- u3port0: usb-phy@11290900 {
- reg = <0 0x11290800 0 0x700>;
- clocks = <&clk26m>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-
- u2port1: usb-phy@11291000 {
- reg = <0 0x11291000 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- };
-};
-
-Specifying phy control of devices
----------------------------------
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type;
-phy-names for each port are optional.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
-usb30: usb@11270000 {
- ...
- phys = <&u2port0 PHY_TYPE_USB2>, <&u3port0 PHY_TYPE_USB3>;
- phy-names = "usb2-0", "usb3-0";
- ...
-};
-
-
-Layout differences of banks between mt8173/mt2701 and mt2712
--------------------------------------------------------------
-mt8173 and mt2701:
-port offset bank
-shared 0x0000 SPLLC
- 0x0100 FMREG
-u2 port0 0x0800 U2PHY_COM
-u3 port0 0x0900 U3PHYD
- 0x0a00 U3PHYD_BANK2
- 0x0b00 U3PHYA
- 0x0c00 U3PHYA_DA
-u2 port1 0x1000 U2PHY_COM
-u3 port1 0x1100 U3PHYD
- 0x1200 U3PHYD_BANK2
- 0x1300 U3PHYA
- 0x1400 U3PHYA_DA
-u2 port2 0x1800 U2PHY_COM
- ...
-
-mt2712:
-port offset bank
-u2 port0 0x0000 MISC
- 0x0100 FMREG
- 0x0300 U2PHY_COM
-u3 port0 0x0700 SPLLC
- 0x0800 CHIP
- 0x0900 U3PHYD
- 0x0a00 U3PHYD_BANK2
- 0x0b00 U3PHYA
- 0x0c00 U3PHYA_DA
-u2 port1 0x1000 MISC
- 0x1100 FMREG
- 0x1300 U2PHY_COM
-u3 port1 0x1700 SPLLC
- 0x1800 CHIP
- 0x1900 U3PHYD
- 0x1a00 U3PHYD_BANK2
- 0x1b00 U3PHYA
- 0x1c00 U3PHYA_DA
-u2 port2 0x2000 MISC
- ...
-
- SPLLC shared by u3 ports and FMREG shared by u2 ports on
-mt8173/mt2701 are put back into each port; a new bank MISC for
-u2 ports and CHIP for u3 ports are added on mt2712.

-MediaTek Universal Flash Storage (UFS) M-PHY binding
---------------------------------------------------------
-
-UFS M-PHY nodes are defined to describe on-chip UFS M-PHY hardware macro.
-Each UFS M-PHY node should have its own node.
-
-To bind UFS M-PHY with UFS host controller, the controller node should
-contain a phandle reference to UFS M-PHY node.
-
-Required properties for UFS M-PHY nodes:
-- compatible : Compatible list, contains the following controller:
- "mediatek,mt8183-ufsphy" for ufs phy
- persent on MT81xx chipsets.
-- reg : Address and length of the UFS M-PHY register set.
-- #phy-cells : This property shall be set to 0.
-- clocks : List of phandle and clock specifier pairs.
-- clock-names : List of clock input name strings sorted in the same
- order as the clocks property. Following clocks are
- mandatory.
- "unipro": Unipro core control clock.
- "mp": M-PHY core control clock.
-
-Example:
-
- ufsphy: phy@11fa0000 {
- compatible = "mediatek,mt8183-ufsphy";
- reg = <0 0x11fa0000 0 0xc000>;
- #phy-cells = <0>;
-
- clocks = <&infracfg_ao INFRACFG_AO_UNIPRO_SCK_CG>,
- <&infracfg_ao INFRACFG_AO_UFS_MP_SAP_BCLK_CG>;
- clock-names = "unipro", "mp";
- };
-
- ufshci@11270000 {
- ...
- phys = <&ufsphy>;
- };

-MediaTek musb DRD/OTG controller
--------------------------------------------
-
-Required properties:
- - compatible : should be one of:
- "mediatek,mt2701-musb"
- ...
- followed by "mediatek,mtk-musb"
- - reg : specifies physical base address and size of
- the registers
- - interrupts : interrupt used by musb controller
- - interrupt-names : must be "mc"
- - phys : PHY specifier for the OTG phy
- - dr_mode : should be one of "host", "peripheral" or "otg",
- refer to usb/generic.txt
- - clocks : a list of phandle + clock-specifier pairs, one for
- each entry in clock-names
- - clock-names : must contain "main", "mcu", "univpll"
- for clocks of controller
-
-Optional properties:
- - power-domains : a phandle to USB power domain node to control USB's
- MTCMOS
-
-Required child nodes:
- usb connector node as defined in bindings/connector/usb-connector.yaml
-Optional properties:
- - id-gpios : input GPIO for USB ID pin.
- - vbus-gpios : input GPIO for USB VBUS pin.
- - vbus-supply : reference to the VBUS regulator, needed when supports
- dual-role mode
- - usb-role-switch : use USB Role Switch to support dual-role switch, see
- usb/generic.txt.
-
-Example:
-
-usb2: usb@11200000 {
- compatible = "mediatek,mt2701-musb",
- "mediatek,mtk-musb";
- reg = <0 0x11200000 0 0x1000>;

-MT8173 xHCI
-
-The device node for Mediatek SOC USB3.0 host controller
-
-There are two scenarios: the first one only supports xHCI driver;
-the second one supports dual-role mode, and the host is based on xHCI
-driver. Take account of backward compatibility, we divide bindings
-into two parts.
-
-1st: only supports xHCI driver
-------------------------------------------------------------------------
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for xHCI MAC and "ippc" for IP port control
- - interrupts : interrupt used by the controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain
- "sys_ck": controller clock used by normal mode,
- the following ones are optional:
- "ref_ck": reference clock used by low power mode etc,
- "mcu_ck": mcu_bus clock for register access,
- "dma_ck": dma_bus clock for data transfer by DMA,
- "xhci_ck": controller clock
-
- - phys : see usb-hcd.yaml in the current directory
-
-Optional properties:
- - wakeup-source : enable USB remote wakeup;
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between xHCI and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
- - pinctrl-names : a pinctrl state named "default" must be defined
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
- - imod-interval-ns: default interrupt moderation interval is 5000ns
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Example:
-usb30: usb@11270000 {
- compatible = "mediatek,mt8173-xhci";
- reg = <0 0x11270000 0 0x1000>,
- <0 0x11280700 0 0x0100>;
- reg-names = "mac", "ippc";
- interrupts = <GIC_SPI 115 IRQ_TYPE_LEVEL_LOW>;
- power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
- clocks = <&topckgen CLK_TOP_USB30_SEL>, <&clk26m>,
- <&pericfg CLK_PERI_USB0>,
- <&pericfg CLK_PERI_USB1>;
- clock-names = "sys_ck", "ref_ck";
- phys = <&phy_port0 PHY_TYPE_USB3>,
- <&phy_port1 PHY_TYPE_USB2>;
- vusb33-supply = <&mt6397_vusb_reg>;
- vbus-supply = <&usb_p1_vbus>;
- usb3-lpm-capable;
- mediatek,syscon-wakeup = <&pericfg 0x400 1>;
- wakeup-source;
- imod-interval-ns = <10000>;
-};
-
-2nd: dual-role mode with xHCI driver
-------------------------------------------------------------------------
-
-In the case, xhci is added as subnode to mtu3. An example and the DT binding
-details of mtu3 can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtu3.txt
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for xHCI MAC
- - interrupts : interrupt used by the host controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck", and the following ones are optional:
- "ref_ck", "mcu_ck" and "dma_ck", "xhci_ck"
-
-Optional properties:

- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
- - pinctrl-names : a pinctrl state named "default" must be defined
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
- - imod-interval-ns: default interrupt moderation interval is 5000ns
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Example:
-usb30: usb@11270000 {
- compatible = "mediatek,mt8173-xhci";
- reg = <0 0x11270000 0 0x1000>,

- imod-interval-ns = <10000>;
-};
-
-2nd: dual-role mode with xHCI driver
-------------------------------------------------------------------------
-
-In the case, xhci is added as subnode to mtu3. An example and the DT binding
-details of mtu3 can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtu3.txt
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for xHCI MAC
- - interrupts : interrupt used by the host controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck", and the following ones are optional:
- "ref_ck", "mcu_ck" and "dma_ck", "xhci_ck"
-
-Optional properties:
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
-
-Example:
-usb30: usb@11270000 {
- compatible = "mediatek,mt8173-xhci";
- reg = <0 0x11270000 0 0x1000>;

v5: changes suggested by Rob
1. refer to usb-xhci.yaml instead of usb-hcd.yaml
2. remove unnecessary maxItems
3. add items for all phys may be supported
4. change pattern, and limit pattern length of patternProperties
v4: update it according to Rob's suggestion
1. modify dictionary of phys
2. fix endentation in "mediatek,syscon-wakeup" items
3. remove reference to usb-hcd.yaml
v3:
1. fix yamllint warning
2. remove pinctrl* properties supported by default suggested by Rob

-MT8173 xHCI
-
-The device node for Mediatek SOC USB3.0 host controller
-
-There are two scenarios: the first one only supports xHCI driver;
-the second one supports dual-role mode, and the host is based on xHCI
-driver. Take account of backward compatibility, we divide bindings
-into two parts.
-
-1st: only supports xHCI driver
-------------------------------------------------------------------------
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"

- - reg-names: should be "mac" for xHCI MAC and "ippc" for IP port control
- - interrupts : interrupt used by the controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain
- "sys_ck": controller clock used by normal mode,
- the following ones are optional:
- "ref_ck": reference clock used by low power mode etc,
- "mcu_ck": mcu_bus clock for register access,
- "dma_ck": dma_bus clock for data transfer by DMA,
- "xhci_ck": controller clock
-
- - phys : see usb-hcd.yaml in the current directory
-
-Optional properties:
- - wakeup-source : enable USB remote wakeup;
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between xHCI and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
- - pinctrl-names : a pinctrl state named "default" must be defined
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
- - imod-interval-ns: default interrupt moderation interval is 5000ns
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.

-MT8173 xHCI
-
-The device node for Mediatek SOC USB3.0 host controller
-
-There are two scenarios: the first one only supports xHCI driver;
-the second one supports dual-role mode, and the host is based on xHCI
-driver. Take account of backward compatibility, we divide bindings
-into two parts.
-
-1st: only supports xHCI driver
-------------------------------------------------------------------------
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for xHCI MAC and "ippc" for IP port control
- - interrupts : interrupt used by the controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain
- "sys_ck": controller clock used by normal mode,
- the following ones are optional:
- "ref_ck": reference clock used by low power mode etc,
- "mcu_ck": mcu_bus clock for register access,
- "dma_ck": dma_bus clock for data transfer by DMA,
- "xhci_ck": controller clock
-
- - phys : see usb-hcd.yaml in the current directory
-
-Optional properties:
- - wakeup-source : enable USB remote wakeup;
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between xHCI and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
- - pinctrl-names : a pinctrl state named "default" must be defined
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
- - imod-interval-ns: default interrupt moderation interval is 5000ns
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Example:
-usb30: usb@11270000 {
- compatible = "mediatek,mt8173-xhci";
- reg = <0 0x11270000 0 0x1000>,
- <0 0x11280700 0 0x0100>;
- reg-names = "mac", "ippc";
- interrupts = <GIC_SPI 115 IRQ_TYPE_LEVEL_LOW>;
- power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
- clocks = <&topckgen CLK_TOP_USB30_SEL>, <&clk26m>,
- <&pericfg CLK_PERI_USB0>,
- <&pericfg CLK_PERI_USB1>;
- clock-names = "sys_ck", "ref_ck";
- phys = <&phy_port0 PHY_TYPE_USB3>,
- <&phy_port1 PHY_TYPE_USB2>;
- vusb33-supply = <&mt6397_vusb_reg>;
- vbus-supply = <&usb_p1_vbus>;
- usb3-lpm-capable;
- mediatek,syscon-wakeup = <&pericfg 0x400 1>;
- wakeup-source;
- imod-interval-ns = <10000>;
-};
-
-2nd: dual-role mode with xHCI driver
-------------------------------------------------------------------------
-
-In the case, xhci is added as subnode to mtu3. An example and the DT binding
-details of mtu3 can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtu3.txt
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-xhci", "mediatek,mtk-xhci",
- soc-model is the name of SoC, such as mt8173, mt2712 etc, when using
- "mediatek,mtk-xhci" compatible string, you need SoC specific ones in
- addition, one of:
- - "mediatek,mt8173-xhci"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for xHCI MAC
- - interrupts : interrupt used by the host controller
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
-
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck", and the following ones are optional:
- "ref_ck", "mcu_ck" and "dma_ck", "xhci_ck"
-
-Optional properties:
- - vbus-supply : reference to the VBUS regulator;
- - usb3-lpm-capable : supports USB3.0 LPM
-
-Example:
-usb30: usb@11270000 {
- compatible = "mediatek,mt8173-xhci";
- reg = <0 0x11270000 0 0x1000>;

-The device node for Mediatek USB3.0 DRD controller
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-mtu3", "mediatek,mtu3",
- soc-model is the name of SoC, such as mt8173, mt2712 etc,
- when using "mediatek,mtu3" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt8173-mtu3"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for device IP and "ippc" for IP port control
- - interrupts : interrupt used by the device IP
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck" for clock of controller,
- the following clocks are optional:
- "ref_ck", "mcu_ck" and "dma_ck";
- - phys : see usb-hcd.yaml in the current directory
- - dr_mode : should be one of "host", "peripheral" or "otg",
- refer to usb/generic.txt
-
-Optional properties:
- - #address-cells, #size-cells : should be '2' if the device has sub-nodes
- with 'reg' property
- - ranges : allows valid 1:1 translation between child's address space and
- parent's address space
- - extcon : external connector for vbus and idpin changes detection, needed
- when supports dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and use "usb-role-switch" property instead.
- - vbus-supply : reference to the VBUS regulator, needed when supports
- dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and put into a usb-connector node.
- see connector/usb-connector.yaml.
- - pinctrl-names : a pinctrl state named "default" is optional, and need be
- defined if auto drd switch is enabled, that means the property dr_mode
- is set as "otg", and meanwhile the property "mediatek,enable-manual-drd"
- is not set.
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
- - maximum-speed : valid arguments are "super-speed", "high-speed" and
- "full-speed"; refer to usb/generic.txt
- - usb-role-switch : use USB Role Switch to support dual-role switch, but
- not extcon; see usb/generic.txt.
- - enable-manual-drd : supports manual dual-role switch via debugfs; usually
- used when receptacle is TYPE-A and also wants to support dual-role
- mode.
- - wakeup-source: enable USB remote wakeup of host mode.
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between SSUSB and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Sub-nodes:
-The xhci should be added as subnode to mtu3 as shown in the following example
-if host mode is enabled. The DT binding details of xhci can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtk-xhci.txt
-
-The port would be added as subnode if use "usb-role-switch" property.
- see graph.txt

-The device node for Mediatek USB3.0 DRD controller
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-mtu3", "mediatek,mtu3",
- soc-model is the name of SoC, such as mt8173, mt2712 etc,
- when using "mediatek,mtu3" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt8173-mtu3"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for device IP and "ippc" for IP port control
- - interrupts : interrupt used by the device IP
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck" for clock of controller,
- the following clocks are optional:
- "ref_ck", "mcu_ck" and "dma_ck";
- - phys : see usb-hcd.yaml in the current directory
- - dr_mode : should be one of "host", "peripheral" or "otg",
- refer to usb/generic.txt
-
-Optional properties:
- - #address-cells, #size-cells : should be '2' if the device has sub-nodes
- with 'reg' property
- - ranges : allows valid 1:1 translation between child's address space and
- parent's address space
- - extcon : external connector for vbus and idpin changes detection, needed
- when supports dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and use "usb-role-switch" property instead.
- - vbus-supply : reference to the VBUS regulator, needed when supports
- dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and put into a usb-connector node.
- see connector/usb-connector.yaml.
- - pinctrl-names : a pinctrl state named "default" is optional, and need be
- defined if auto drd switch is enabled, that means the property dr_mode
- is set as "otg", and meanwhile the property "mediatek,enable-manual-drd"
- is not set.
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
- - maximum-speed : valid arguments are "super-speed", "high-speed" and
- "full-speed"; refer to usb/generic.txt
- - usb-role-switch : use USB Role Switch to support dual-role switch, but
- not extcon; see usb/generic.txt.
- - enable-manual-drd : supports manual dual-role switch via debugfs; usually
- used when receptacle is TYPE-A and also wants to support dual-role
- mode.
- - wakeup-source: enable USB remote wakeup of host mode.
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between SSUSB and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Sub-nodes:
-The xhci should be added as subnode to mtu3 as shown in the following example
-if host mode is enabled. The DT binding details of xhci can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtk-xhci.txt
-
-The port would be added as subnode if use "usb-role-switch" property.
- see graph.txt
-
-Example:
-ssusb: usb@11271000 {
- compatible = "mediatek,mt8173-mtu3";
- reg = <0 0x11271000 0 0x3000>,

-The device node for Mediatek USB3.0 DRD controller
-
-Required properties:
- - compatible : should be "mediatek,<soc-model>-mtu3", "mediatek,mtu3",
- soc-model is the name of SoC, such as mt8173, mt2712 etc,
- when using "mediatek,mtu3" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt8173-mtu3"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for device IP and "ippc" for IP port control
- - interrupts : interrupt used by the device IP
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck" for clock of controller,
- the following clocks are optional:
- "ref_ck", "mcu_ck" and "dma_ck";
- - phys : see usb-hcd.yaml in the current directory
- - dr_mode : should be one of "host", "peripheral" or "otg",
- refer to usb/generic.txt
-
-Optional properties:
- - #address-cells, #size-cells : should be '2' if the device has sub-nodes
- with 'reg' property
- - ranges : allows valid 1:1 translation between child's address space and
- parent's address space
- - extcon : external connector for vbus and idpin changes detection, needed
- when supports dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and use "usb-role-switch" property instead.
- - vbus-supply : reference to the VBUS regulator, needed when supports
- dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and put into a usb-connector node.
- see connector/usb-connector.yaml.
- - pinctrl-names : a pinctrl state named "default" is optional, and need be
- defined if auto drd switch is enabled, that means the property dr_mode
- is set as "otg", and meanwhile the property "mediatek,enable-manual-drd"
- is not set.
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
- - maximum-speed : valid arguments are "super-speed", "high-speed" and
- "full-speed"; refer to usb/generic.txt
- - usb-role-switch : use USB Role Switch to support dual-role switch, but
- not extcon; see usb/generic.txt.
- - enable-manual-drd : supports manual dual-role switch via debugfs; usually
- used when receptacle is TYPE-A and also wants to support dual-role
- mode.
- - wakeup-source: enable USB remote wakeup of host mode.
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between SSUSB and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Sub-nodes:
-The xhci should be added as subnode to mtu3 as shown in the following example
-if host mode is enabled. The DT binding details of xhci can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtk-xhci.txt
-
-The port would be added as subnode if use "usb-role-switch" property.
- see graph.txt
