-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>;
