Subject: [v4] dt-bindings: msm: disp: add yaml schemas for DPU and DSI bindings
MSM Mobile Display Subsytem (MDSS) encapsulates sub-blocks
like DPU display controller, DSI etc. Add YAML schema
for the device tree bindings for the same.
Signed-off-by: Krishna Manikandan <mkrishn@...eaurora.org>
Changes in v2:
- Changed dpu to DPU (Sam Ravnborg)
- Fixed indentation issues (Sam Ravnborg)
- Added empty line between different properties (Sam Ravnborg)
- Replaced reference txt files with their corresponding
yaml files (Sam Ravnborg)
- Modified the file to use "|" only when it is
necessary (Sam Ravnborg)
Changes in v3:
- Corrected the license used (Rob Herring)
- Added maxItems for properties (Rob Herring)
- Dropped generic descriptions (Rob Herring)
- Added ranges property (Rob Herring)
- Corrected the indendation (Rob Herring)
- Added additionalProperties (Rob Herring)
- Split dsi file into two, one for dsi controller
and another one for dsi phy per target (Rob Herring)
- Corrected description for pinctrl-names (Rob Herring)
- Corrected the examples used in yaml file (Rob Herring)
- Delete dsi.txt and dpu.txt (Rob Herring)
Changes in v4:
- Move schema up by one level (Rob Herring)

-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.

- 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.
