MediaTek GCE

===============



This is temporary node for cmdq driver legacy interface, which compatible

with legacy display driver. This node manage cmdq channels and dispatch to

display.



Required properties:

- compatible: Must be "mediatek,cmdq-ext"

- reg: Address range of the GCE unit

- interrupts: The interrupt signal from the GCE block

- clock: Clocks according to the common clock binding

- clock-names: Must be "GCE" to stand for GCE clock



Example:



	cmdq-ext: cmdq-ext@10212000 {

		compatible = "mediatek,cmdq-ext";

		reg = <0 0x10212000 0 0x1000>;

		interrupts = <GIC_SPI 135 IRQ_TYPE_LEVEL_LOW>;

		clocks = <&infracfg_ao INFRACFG_AO_GCE_CG>;

		clock-names = "GCE";

	};
