3 The following bindings apply to a family of Display Processors sold as
4 licensable IP by ARM Ltd. The bindings describe the Mali DP500, DP550 and
5 DP650 processors that offer multiple composition layers, support for
6 rotation and scaling output.
9 - compatible: should be one of
13 depending on the particular implementation present in the hardware
14 - reg: Physical base address and size of the block of registers used by
16 - interrupts: Interrupt list, as defined in ../interrupt-controller/interrupts.txt,
17 interrupt client nodes.
18 - interrupt-names: name of the engine inside the processor that will
19 use the corresponding interrupt. Should be one of "DE" or "SE".
20 - clocks: A list of phandle + clock-specifier pairs, one for each entry
22 - clock-names: A list of clock names. It should contain:
23 - "pclk": for the APB interface clock
24 - "aclk": for the AXI interface clock
25 - "mclk": for the main processor clock
26 - "pxlclk": for the pixel clock feeding the output PLL of the processor.
27 - arm,malidp-output-port-lines: Array of u8 values describing the number
28 of output lines per channel (R, G and B).
31 - port: The Mali DP connection to an encoder input port. The connection
32 is modelled using the OF graph bindings specified in
33 Documentation/devicetree/bindings/graph.txt
36 - memory-region: phandle to a node describing memory (see
37 Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
38 to be used for the framebuffer; if not present, the framebuffer may
39 be located anywhere in memory.
40 - arm,malidp-arqos-high-level: integer of u32 value describing the ARQoS
41 levels of DP500's QoS signaling.
