 1ARC PGU
 2
 3This is a display controller found on several development boards produced
 4by Synopsys. The ARC PGU is an RGB streamer that reads the data from a
 5framebuffer and sends it to a single digital encoder (usually HDMI).
 6
 7Required properties:
 8  - compatible: "snps,arcpgu"
 9  - reg: Physical base address and length of the controller's registers.
10  - clocks: A list of phandle + clock-specifier pairs, one for each
11    entry in 'clock-names'.
12  - clock-names: A list of clock names. For ARC PGU it should contain:
13      - "pxlclk" for the clock feeding the output PLL of the controller.
14
15Required sub-nodes:
16  - port: The PGU connection to an encoder chip.

26		clocks = <&clock_node>;
27		clock-names = "pxlclk";
