1 ARC PGU
2
3 This is a display controller found on several development boards produced
4 by Synopsys. The ARC PGU is an RGB streamer that reads the data from a
5 framebuffer and sends it to a single digital encoder (usually HDMI).
6
7 Required 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
15 Required sub-nodes:
16   - port: The PGU connection to an encoder chip.
