mfd: dt: Add bindings for the Aspeed SoC Display Controller (GFX) (0f174769) · Commits · 戴 / test

The Aspeed SoC Display Controller is presented as a syscon device to arbitrate access by display and pinmux drivers. Video pinmux configuration on fifth generation SoCs depends on bits in both the System Control Unit and the Display Controller. Signed-off-by:

		* Device tree bindings for Aspeed SoC Display Controller (GFX)

		The Aspeed SoC Display Controller primarily does as its name suggests, but also
		participates in pinmux requests on the g5 SoCs. It is therefore considered a
		syscon device.

		Required properties:
		- compatible: "aspeed,ast2500-gfx", "syscon"
		- reg: contains offset/length value of the GFX memory
		region.

		Example:

		gfx: display@1e6e6000 {
		compatible = "aspeed,ast2500-gfx", "syscon";
		reg = <0x1e6e6000 0x1000>;
		};
