This patchset is to convert ci-hdrc-usb2 and usbmisc-imx to yaml format.
There are compatible strings not landed in binding doc, but in device tree,
so run dtbs_check on the single yaml convertion patch will report
dtbs_check failure. If apply the whole patchset, there will be no failure.
I put Greg as maintainer of the yaml file, because I not sure who should
be put there.
Peng Fan (6):

-* USB2 ChipIdea USB controller for ci13xxx
-
-Required properties:
-- compatible: should be one of:
- "fsl,imx23-usb"
- "fsl,imx27-usb"
- "fsl,imx28-usb"
- "fsl,imx6q-usb"
- "fsl,imx6sl-usb"
- "fsl,imx6sx-usb"
- "fsl,imx6ul-usb"
- "fsl,imx7d-usb"
- "fsl,imx7ulp-usb"
- "lsi,zevio-usb"
- "qcom,ci-hdrc"
- "chipidea,usb2"
- "xlnx,zynq-usb-2.20a"
- "nvidia,tegra20-udc"
- "nvidia,tegra30-udc"
- "nvidia,tegra114-udc"
- "nvidia,tegra124-udc"
-- reg: base address and length of the registers
-- interrupts: interrupt for the USB controller
-
-Recommended properies:
-- phy_type: the type of the phy connected to the core. Should be one
- of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
- property the PORTSC register won't be touched.
-- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
-
-Deprecated properties:
-- usb-phy: phandle for the PHY device. Use "phys" instead.
-- fsl,usbphy: phandle of usb phy that connects to the port. Use "phys" instead.
-
-Optional properties:
-- clocks: reference to the USB clock
-- phys: reference to the USB PHY
-- phy-names: should be "usb-phy"
-- vbus-supply: reference to the VBUS regulator
-- maximum-speed: limit the maximum connection speed to "full-speed".
-- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts
-- itc-setting: interrupt threshold control register control, the setting
- should be aligned with ITC bits at register USBCMD.
-- ahb-burst-config: it is vendor dependent, the required value should be
- aligned with AHBBRST at SBUSCFG, the range is from 0x0 to 0x7. This
- property is used to change AHB burst configuration, check the chipidea
- spec for meaning of each value. If this property is not existed, it
- will use the reset value.
-- tx-burst-size-dword: it is vendor dependent, the tx burst size in dword
- (4 bytes), This register represents the maximum length of a the burst
- in 32-bit words while moving data from system memory to the USB
- bus, the value of this property will only take effect if property
- "ahb-burst-config" is set to 0, if this property is missing the reset
- default of the hardware implementation will be used.
-- rx-burst-size-dword: it is vendor dependent, the rx burst size in dword
- (4 bytes), This register represents the maximum length of a the burst
- in 32-bit words while moving data from the USB bus to system memory,
- the value of this property will only take effect if property
- "ahb-burst-config" is set to 0, if this property is missing the reset
- default of the hardware implementation will be used.
-- extcon: phandles to external connector devices. First phandle should point to
- external connector, which provide "USB" cable events, the second should point
- to external connector device, which provide "USB-HOST" cable events. If one
- of the external connector devices is not required, empty <0> phandle should
- be specified.
-- phy-clkgate-delay-us: the delay time (us) between putting the PHY into
- low power mode and gating the PHY clock.
-- non-zero-ttctrl-ttha: after setting this property, the value of register
- ttctrl.ttha will be 0x7f; if not, the value will be 0x0, this is the default
- value. It needs to be very carefully for setting this property, it is
- recommended that consult with your IC engineer before setting this value.
- On the most of chipidea platforms, the "usage_tt" flag at RTL is 0, so this
- property only affects siTD.
- If this property is not set, the max packet size is 1023 bytes, and if
- the total of packet size for pervious transactions are more than 256 bytes,
- it can't accept any transactions within this frame. The use case is single
- transaction, but higher frame rate.
- If this property is set, the max packet size is 188 bytes, it can handle
- more transactions than above case, it can accept transactions until it
- considers the left room size within frame is less than 188 bytes, software
- needs to make sure it does not send more than 90%
- maximum_periodic_data_per_frame. The use case is multiple transactions, but
- less frame rate.
-- mux-controls: The mux control for toggling host/device output of this
- controller. It's expected that a mux state of 0 indicates device mode and a
- mux state of 1 indicates host mode.
-- mux-control-names: Shall be "usb_switch" if mux-controls is specified.
-- pinctrl-names: Names for optional pin modes in "default", "host", "device".
- In case of HSIC-mode, "idle" and "active" pin modes are mandatory. In this
- case, the "idle" state needs to pull down the data and strobe pin
- and the "active" state needs to pull up the strobe pin.
-- pinctrl-n: alternate pin modes
-
-i.mx specific properties
-- fsl,usbmisc: phandler of non-core register device, with one
- argument that indicate usb controller index
-- disable-over-current: disable over current detect
-- over-current-active-low: over current signal polarity is active low.
-- over-current-active-high: over current signal polarity is active high.
- It's recommended to specify the over current polarity.
-- power-active-high: power signal polarity is active high
-- external-vbus-divider: enables off-chip resistor divider for Vbus
-- samsung,picophy-pre-emp-curr-control: HS Transmitter Pre-Emphasis Current
- Control. This signal controls the amount of current sourced to the
- USB_OTG*_DP and USB_OTG*_DN pins after a J-to-K or K-to-J transition.
- The range is from 0x0 to 0x3, the default value is 0x1.
- Details can refer to TXPREEMPAMPTUNE0 bits of USBNC_n_PHY_CFG1.
-- samsung,picophy-dc-vol-level-adjust: HS DC Voltage Level Adjustment.
- Adjust the high-speed transmitter DC level voltage.
- The range is from 0x0 to 0xf, the default value is 0x3.
- Details can refer to TXVREFTUNE0 bits of USBNC_n_PHY_CFG1.
-
-Example:
-
- usb@f7ed0000 {
- compatible = "chipidea,usb2";
- reg = <0xf7ed0000 0x10000>;
- interrupts = <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/patch/
This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Cool, is nxp going to pay me to maintain this? If not, then don't be
assigning such a thing to someone else. Why can you not maintain it?
Assigning a file to someone without even asking them is a bit odd,
please never do that.

Hi Peng,
Thanks for this patchset.
Since xu.yang_2@nxp.com is now actively working on this IP for iMX, so he knows

this?
Thanks

You can assign me as maintainer temporarily.
By the way, it seems that the following compatible strings should be added too.
fsl,imx25-usbmisc
fsl,imx27-usbmisc
fsl,imx35-usbmisc
fsl,imx51-usbmisc
fsl,imx53-usbmisc

Describe the items. Otherwise this does not make much sense, because

The allOf section has below restriction, I not understand well that still need to describe
items here?
- if:
properties:
phy_type:
const: hsic
required:
- phy_type
then:
properties:
pinctrl-names:
items:
- const: idle
- const: active
else:
properties:
pinctrl-names:
oneOf:
- items:
- const: default
- enum:
- host
- device
- items:
- const: default
