-Description:
-
-Device tree bindings for MSM Mobile Display Subsytem(MDSS) that encapsulates
-sub-blocks like DPU display controller, DSI and DP interfaces etc.
-The DPU display controller is found in SDM845 SoC.
-
-MDSS:
-Required properties:
-- compatible: "qcom,sdm845-mdss", "qcom,sc7180-mdss"
-- reg: physical base address and length of contoller's registers.
-- reg-names: register region names. The following region is required:
- * "mdss"
-- power-domains: a power domain consumer specifier according to
- Documentation/devicetree/bindings/power/power_domain.txt
-- clocks: list of clock specifiers for clocks needed by the device.
-- clock-names: device clock names, must be in same order as clocks property.
- The following clocks are required:
- * "iface"
- * "bus"
- * "core"
-- interrupts: interrupt signal from MDSS.
-- interrupt-controller: identifies the node as an interrupt controller.
-- #interrupt-cells: specifies the number of cells needed to encode an interrupt
- source, should be 1.
-- iommus: phandle of iommu device node.
-- #address-cells: number of address cells for the MDSS children. Should be 1.
-- #size-cells: Should be 1.
-- ranges: parent bus address space is the same as the child bus address space.
-- interconnects : interconnect path specifier for MDSS according to
- Documentation/devicetree/bindings/interconnect/interconnect.txt. Should be
- 2 paths corresponding to 2 AXI ports.
-- interconnect-names : MDSS will have 2 port names to differentiate between the
- 2 interconnect paths defined with interconnect specifier.
-
-Optional properties:
-- assigned-clocks: list of clock specifiers for clocks needing rate assignment
-- assigned-clock-rates: list of clock frequencies sorted in the same order as
- the assigned-clocks property.
-
-MDP:
-Required properties:
-- compatible: "qcom,sdm845-dpu", "qcom,sc7180-dpu"
-- reg: physical base address and length of controller's registers.
-- reg-names : register region names. The following region is required:
- * "mdp"
- * "vbif"
-- clocks: list of clock specifiers for clocks needed by the device.
-- clock-names: device clock names, must be in same order as clocks property.
- The following clocks are required.
- * "bus"
- * "iface"
- * "core"
- * "vsync"
-- interrupts: interrupt line from DPU to MDSS.
-- ports: contains the list of output ports from DPU device. These ports connect
- to interfaces that are external to the DPU hardware, such as DSI, DP etc.
-
- Each output port contains an endpoint that describes how it is connected to an
- external interface. These are described by the standard properties documented
- here:
- Documentation/devicetree/bindings/graph.txt
- Documentation/devicetree/bindings/media/video-interfaces.txt
-
- Port 0 -> DPU_INTF1 (DSI1)
- Port 1 -> DPU_INTF2 (DSI2)
-
-Optional properties:
-- assigned-clocks: list of clock specifiers for clocks needing rate assignment
-- assigned-clock-rates: list of clock frequencies sorted in the same order as
- the assigned-clocks property.

-Description:
-
-Device tree bindings for MSM Mobile Display Subsytem(MDSS) that encapsulates
-sub-blocks like DPU display controller, DSI and DP interfaces etc.
-The DPU display controller is found in SDM845 SoC.
-
-MDSS:
-Required properties:
-- compatible: "qcom,sdm845-mdss", "qcom,sc7180-mdss"
-- reg: physical base address and length of contoller's registers.
-- reg-names: register region names. The following region is required:
- * "mdss"
-- power-domains: a power domain consumer specifier according to
- Documentation/devicetree/bindings/power/power_domain.txt
-- clocks: list of clock specifiers for clocks needed by the device.
-- clock-names: device clock names, must be in same order as clocks property.
- The following clocks are required:
- * "iface"
- * "bus"
- * "core"
-- interrupts: interrupt signal from MDSS.
-- interrupt-controller: identifies the node as an interrupt controller.
-- #interrupt-cells: specifies the number of cells needed to encode an interrupt
- source, should be 1.
-- iommus: phandle of iommu device node.
-- #address-cells: number of address cells for the MDSS children. Should be 1.
-- #size-cells: Should be 1.
-- ranges: parent bus address space is the same as the child bus address space.
-- interconnects : interconnect path specifier for MDSS according to
- Documentation/devicetree/bindings/interconnect/interconnect.txt. Should be
- 2 paths corresponding to 2 AXI ports.
-- interconnect-names : MDSS will have 2 port names to differentiate between the
- 2 interconnect paths defined with interconnect specifier.
-
-Optional properties:
-- assigned-clocks: list of clock specifiers for clocks needing rate assignment
-- assigned-clock-rates: list of clock frequencies sorted in the same order as
- the assigned-clocks property.
-
-MDP:
-Required properties:
-- compatible: "qcom,sdm845-dpu", "qcom,sc7180-dpu"
-- reg: physical base address and length of controller's registers.
-- reg-names : register region names. The following region is required:
- * "mdp"
- * "vbif"
-- clocks: list of clock specifiers for clocks needed by the device.
-- clock-names: device clock names, must be in same order as clocks property.
- The following clocks are required.
- * "bus"
- * "iface"
- * "core"
- * "vsync"
-- interrupts: interrupt line from DPU to MDSS.
-- ports: contains the list of output ports from DPU device. These ports connect
- to interfaces that are external to the DPU hardware, such as DSI, DP etc.
-
- Each output port contains an endpoint that describes how it is connected to an
- external interface. These are described by the standard properties documented
- here:
- Documentation/devicetree/bindings/graph.txt
- Documentation/devicetree/bindings/media/video-interfaces.txt
-
- Port 0 -> DPU_INTF1 (DSI1)
- Port 1 -> DPU_INTF2 (DSI2)
-
-Optional properties:
-- assigned-clocks: list of clock specifiers for clocks needing rate assignment
-- assigned-clock-rates: list of clock frequencies sorted in the same order as
- the assigned-clocks property.

-DSI Controller:
-Required properties:
-- compatible:
- * "qcom,mdss-dsi-ctrl"
-- reg: Physical base address and length of the registers of controller
-- reg-names: The names of register regions. The following regions are required:
- * "dsi_ctrl"
-- interrupts: The interrupt signal from the DSI block.
-- power-domains: Should be <&mmcc MDSS_GDSC>.

- * "mdp_core"
- * "iface"
- * "bus"
- * "core_mmss"
- * "byte"
- * "pixel"
- * "core"
- For DSIv2, we need an additional clock:
- * "src"
- For DSI6G v2.0 onwards, we need also need the clock:
- * "byte_intf"
-- assigned-clocks: Parents of "byte" and "pixel" for the given platform.
-- assigned-clock-parents: The Byte clock and Pixel clock PLL outputs provided
- by a DSI PHY block. See [1] for details on clock bindings.
-- vdd-supply: phandle to vdd regulator device node
-- vddio-supply: phandle to vdd-io regulator device node
-- vdda-supply: phandle to vdda regulator device node
-- phys: phandle to DSI PHY device node
-- phy-names: the name of the corresponding PHY device
-- syscon-sfpb: A phandle to mmss_sfpb syscon node (only for DSIv2)
-- ports: Contains 2 DSI controller ports as child nodes. Each port contains
- an endpoint subnode as defined in [2] and [3].
-
-Optional properties:
-- panel@0: Node of panel connected to this DSI controller.
- See files in [4] for each supported panel.
-- qcom,dual-dsi-mode: Boolean value indicating if the DSI controller is
- driving a panel which needs 2 DSI links.
-- qcom,master-dsi: Boolean value indicating if the DSI controller is driving
- the master link of the 2-DSI panel.
-- qcom,sync-dual-dsi: Boolean value indicating if the DSI controller is
- driving a 2-DSI panel whose 2 links need receive command simultaneously.

-
- DSI Endpoint properties:
- - remote-endpoint: For port@0, set to phandle of the connected panel/bridge's
- input endpoint. For port@1, set to the MDP interface output. See [2] for
- device graph info.
-
- - data-lanes: this describes how the physical DSI data lanes are mapped
- to the logical lanes on the given platform. The value contained in
- index n describes what physical lane is mapped to the logical lane n
- (DATAn, where n lies between 0 and 3). The clock lane position is fixed
- and can't be changed. Hence, they aren't a part of the DT bindings. See
- [3] for more info on the data-lanes property.
-
- For example:
-
- data-lanes = <3 0 1 2>;
-
- The above mapping describes that the logical data lane DATA0 is mapped to
- the physical data lane DATA3, logical DATA1 to physical DATA0, logic DATA2
- to phys DATA1 and logic DATA3 to phys DATA2.
-
- There are only a limited number of physical to logical mappings possible:
- <0 1 2 3>
- <1 2 3 0>
- <2 3 0 1>
- <3 0 1 2>
- <0 3 2 1>
- <1 0 3 2>
- <2 1 0 3>
- <3 2 1 0>

- * "qcom,dsi-phy-7nm"
- * "qcom,dsi-phy-7nm-8150"
-- reg: Physical base address and length of the registers of PLL, PHY. Some
- revisions require the PHY regulator base address, whereas others require the
- PHY lane base address. See below for each PHY revision.
-- reg-names: The names of register regions. The following regions are required:
- For DSI 28nm HPM/LP/8960 PHYs and 20nm PHY:
- * "dsi_pll"
- * "dsi_phy"
- * "dsi_phy_regulator"
- For DSI 14nm, 10nm and 7nm PHYs:
- * "dsi_pll"
- * "dsi_phy"
- * "dsi_phy_lane"
-- clock-cells: Must be 1. The DSI PHY block acts as a clock provider, creating
- 2 clocks: A byte clock (index 0), and a pixel clock (index 1).
-- power-domains: Should be <&mmcc MDSS_GDSC>.
-- clocks: Phandles to device clocks. See [1] for details on clock bindings.
-- clock-names: the following clocks are required:
- * "iface"
- * "ref" (only required for new DTS files/entries)
- For 28nm HPM/LP, 28nm 8960 PHYs:

- For 20nm PHY:
-- vddio-supply: phandle to vdd-io regulator device node
-- vcca-supply: phandle to vcca regulator device node
- For 14nm PHY:
-- vcca-supply: phandle to vcca regulator device node
- For 10nm and 7nm PHY:
-- vdds-supply: phandle to vdds regulator device node
-
-Optional properties:
-- qcom,dsi-phy-regulator-ldo-mode: Boolean value indicating if the LDO mode PHY
- regulator is wanted.
-- qcom,mdss-mdp-transfer-time-us: Specifies the dsi transfer time for command mode
- panels in microseconds. Driver uses this number to adjust
- the clock rate according to the expected transfer time.
- Increasing this value would slow down the mdp processing
- and can result in slower performance.
- Decreasing this value can speed up the mdp processing,
- but this can also impact power consumption.
- As a rule this time should not be higher than the time
- that would be expected with the processing at the
- dsi link rate since anyways this would be the maximum
- transfer time that could be achieved.
- If ping pong split is enabled, this time should not be higher
- than two times the dsi link rate time.
- If the property is not specified, then the default value is 14000 us.

-
- DSI Endpoint properties:
- - remote-endpoint: For port@0, set to phandle of the connected panel/bridge's
- input endpoint. For port@1, set to the MDP interface output. See [2] for
- device graph info.
-
- - data-lanes: this describes how the physical DSI data lanes are mapped
- to the logical lanes on the given platform. The value contained in
- index n describes what physical lane is mapped to the logical lane n
- (DATAn, where n lies between 0 and 3). The clock lane position is fixed
- and can't be changed. Hence, they aren't a part of the DT bindings. See
- [3] for more info on the data-lanes property.
-
- For example:
-
- data-lanes = <3 0 1 2>;
-
- The above mapping describes that the logical data lane DATA0 is mapped to
- the physical data lane DATA3, logical DATA1 to physical DATA0, logic DATA2
- to phys DATA1 and logic DATA3 to phys DATA2.
-
- There are only a limited number of physical to logical mappings possible:
- <0 1 2 3>
- <1 2 3 0>
- <2 3 0 1>
- <3 0 1 2>
- <0 3 2 1>
- <1 0 3 2>
- <2 1 0 3>
- <3 2 1 0>
-
-DSI PHY:
-Required properties:
-- compatible: Could be the following
- * "qcom,dsi-phy-28nm-hpm"
- * "qcom,dsi-phy-28nm-lp"
- * "qcom,dsi-phy-20nm"
- * "qcom,dsi-phy-28nm-8960"
- * "qcom,dsi-phy-14nm"
- * "qcom,dsi-phy-14nm-660"
- * "qcom,dsi-phy-10nm"
- * "qcom,dsi-phy-10nm-8998"
- * "qcom,dsi-phy-7nm"
- * "qcom,dsi-phy-7nm-8150"
-- reg: Physical base address and length of the registers of PLL, PHY. Some
- revisions require the PHY regulator base address, whereas others require the
- PHY lane base address. See below for each PHY revision.
-- reg-names: The names of register regions. The following regions are required:
- For DSI 28nm HPM/LP/8960 PHYs and 20nm PHY:
- * "dsi_pll"
- * "dsi_phy"
- * "dsi_phy_regulator"
- For DSI 14nm, 10nm and 7nm PHYs:
- * "dsi_pll"
- * "dsi_phy"
- * "dsi_phy_lane"
-- clock-cells: Must be 1. The DSI PHY block acts as a clock provider, creating
- 2 clocks: A byte clock (index 0), and a pixel clock (index 1).
-- power-domains: Should be <&mmcc MDSS_GDSC>.
-- clocks: Phandles to device clocks. See [1] for details on clock bindings.
-- clock-names: the following clocks are required:
- * "iface"
- * "ref" (only required for new DTS files/entries)
- For 28nm HPM/LP, 28nm 8960 PHYs:
-- vddio-supply: phandle to vdd-io regulator device node
- For 20nm PHY:
-- vddio-supply: phandle to vdd-io regulator device node
-- vcca-supply: phandle to vcca regulator device node
- For 14nm PHY:
-- vcca-supply: phandle to vcca regulator device node
- For 10nm and 7nm PHY:
-- vdds-supply: phandle to vdds regulator device node
-
-Optional properties:
-- qcom,dsi-phy-regulator-ldo-mode: Boolean value indicating if the LDO mode PHY
- regulator is wanted.
-- qcom,mdss-mdp-transfer-time-us: Specifies the dsi transfer time for command mode
- panels in microseconds. Driver uses this number to adjust
- the clock rate according to the expected transfer time.
- Increasing this value would slow down the mdp processing
- and can result in slower performance.
- Decreasing this value can speed up the mdp processing,
- but this can also impact power consumption.
- As a rule this time should not be higher than the time
- that would be expected with the processing at the
- dsi link rate since anyways this would be the maximum
- transfer time that could be achieved.
- If ping pong split is enabled, this time should not be higher
- than two times the dsi link rate time.
- If the property is not specified, then the default value is 14000 us.

This check can fail if there are any dependencies. The base for a patch

Hi Rob,
These are the possible values:
- <0 1 2 3>
- <1 2 3 0>
- <2 3 0 1>
- <3 0 1 2>
- <0 3 2 1>
- <1 0 3 2>
- <2 1 0 3>
- <3 2 1 0>
Shall I follow the below mentioned approach for defining these values ?

Hi Rob,
These are the possible values:
- <0 1 2 3>
- <1 2 3 0>
- <2 3 0 1>
- <3 0 1 2>
- <0 3 2 1>
- <1 0 3 2>
- <2 1 0 3>
- <3 2 1 0>
Shall I follow the below mentioned approach for defining these values ?

Hi Rob,
These are the possible values:
- <0 1 2 3>
- <1 2 3 0>
- <2 3 0 1>
- <3 0 1 2>
- <0 3 2 1>
- <1 0 3 2>
- <2 1 0 3>
- <3 2 1 0>
Shall I follow the below mentioned approach for defining these values ?
