+* 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>;
+};
