1 | ARM Mali-DP | ||
2 | |||
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. | ||
7 | |||
8 | Required properties: | ||
9 | - compatible: should be one of | ||
10 | "arm,mali-dp500" | ||
11 | "arm,mali-dp550" | ||
12 | "arm,mali-dp650" | ||
13 | depending on the particular implementation present in the hardware | ||
14 | - reg: Physical base address and size of the block of registers used by | ||
15 | the processor. | ||
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 | ||
21 | in 'clock-names' | ||
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). | ||
29 | |||
30 | Required sub-nodes: | ||
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 | ||
34 | |||
35 | Optional properties: | ||
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 | |||

43 | |||
44 | / { | ||
45 | ... | ||
46 | |||

54 | clocks = <&oscclk2>, <&fpgaosc0>, <&fpgaosc1>, <&fpgaosc1>; | ||
