[PATCH v2 2/2] dt-bindings: gpu: Convert aspeed-gfx bindings to yaml

[Joel Stanley]

Convert the bindings to yaml and add the ast2600 compatible string.

The legacy mfd description was put in place before the gfx bindings
existed, to document the compatible that is used in the pinctrl
bindings.

-Device tree configuration for the GFX display device on the ASPEED SoCs
-
-Required properties:
-  - compatible
-    * Must be one of the following:
-      + aspeed,ast2500-gfx
-      + aspeed,ast2400-gfx
-    * In addition, the ASPEED pinctrl bindings require the 'syscon' property to
-      be present
-
-  - reg: Physical base address and length of the GFX registers
-
-  - interrupts: interrupt number for the GFX device
-
-  - clocks: clock number used to generate the pixel clock
-
-  - resets: reset line that must be released to use the GFX device
-
-  - memory-region:
-    Phandle to a memory region to allocate from, as defined in
-    Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
-

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

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