[v2] dt-bindings: msm: disp: add yaml schemas for DPU and DSI bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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@xxxxxxxxxxxxxx>

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)

+            data-lanes:
+              description: |
+                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
+                Documentation/devicetree/bindings/media/video-interfaces.txt 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.

+              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 is an optional property.

+                See Documentation/devicetree/bindings/graph.txt for
+                device graph info.
+
+            data-lanes:
+              description: |
+                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
+                Documentation/devicetree/bindings/media/video-interfaces.txt 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.

+            description: |
+              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 is an optional property.
