+The following bindings apply to a family of Display Processors sold as +licensable IP by ARM Ltd. The bindings describe the Mali DP500, DP550 and +DP650 processors that offer multiple composition layers, support for +rotation and scaling output.
+Required properties:
- compatible: should be one of
- "arm,mali-dp500"
- "arm,mali-dp550"
- "arm,mali-dp650"
- depending on the particular implementation present in the hardware
- reg: Physical base address and size of the block of registers used by
- the processor.
- interrupts: Interrupt list, as defined in ../interrupt-controller/interrupts.txt,
- interrupt client nodes.
- interrupt-names: name of the engine inside the processor that will
- use the corresponding interrupt. Should be one of "DE" or "SE".
s/be one of/contain/, s/or/and/, judging by the example.
Otherwise this generally looks fine to me.
Mark.
- clocks: A list of phandle + clock-specifier pairs, one for each entry
- in 'clock-names'
- clock-names: A list of clock names. It should contain:
- "pclk": for the APB interface clock- "aclk": for the AXI interface clock- "mclk": for the main processor clock- "pxlclk": for the pixel clock feeding the output PLL of the processor.
- arm,malidp-output-port-lines: Array of u8 values describing the number
- of output lines per channel (R, G and B).
+Required sub-nodes:
- port: The Mali DP connection to an encoder input port. The connection
- is modelled using the OF graph bindings specified in
- Documentation/devicetree/bindings/graph.txt
+Optional properties:
- memory-region: phandle to a node describing memory (see
- Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
- to be used for the framebuffer; if not present, the framebuffer may
- be located anywhere in memory.
+Example:
+/ {
- ...
- dp0: malidp@6f200000 {
compatible = "arm,mali-dp650";reg = <0 0x6f200000 0 0x20000>;memory-region = <&display_reserved>;interrupts = <0 168 IRQ_TYPE_LEVEL_HIGH>,<0 168 IRQ_TYPE_LEVEL_HIGH>;interrupt-names = "DE", "SE";clocks = <&oscclk2>, <&fpgaosc0>, <&fpgaosc1>, <&fpgaosc1>;clock-names = "pxlclk", "mclk", "aclk", "pclk";arm,malidp-output-port-lines = /bits/ 8 <8 8 8>;port {dp0_output: endpoint {remote-endpoint = <&tda998x_2_input>;};};- };
