-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>;
