+ARM Mali-DP
+
+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".
+ - 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>;
+ };
+ };
+ };
+
+ ...
+};
