		ARC PGU

		This is a display controller found on several development boards produced
		by Synopsys. The ARC PGU is an RGB streamer that reads the data from a
		framebuffer and sends it to a single digital encoder (usually HDMI).

		Required properties:
		- compatible: "snps,arcpgu"
		- reg: Physical base address and length of the controller's registers.
		- clocks: A list of phandle + clock-specifier pairs, one for each
		entry in 'clock-names'.
		- clock-names: A list of clock names. For ARC PGU it should contain:
		- "pxlclk" for the clock feeding the output PLL of the controller.

		Required sub-nodes:
		- port: The PGU connection to an encoder chip.

		Example:

		/ {
		...

		pgu@XXXXXXXX {
		compatible = "snps,arcpgu";
		reg = <0xXXXXXXXX 0x400>;
		clocks = <&clock_node>;
		clock-names = "pxlclk";

		port {
		pgu_output: endpoint {
		remote-endpoint = <&hdmi_enc_input>;
		};
		};
		};
		};
