+Mediatek CRTC Main Device
+================================
+
+The Mediatek CRTC Main device is a crtc device of DRM system.
+
+Required properties:
+- compatible: "mediatek,<chip>-crtc-main"
+- interrupts: The interrupt signal from the CRTC Main block.
+- reg: Physical base address and length of the controller's registers
+- clocks: device clocks
+ See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
+- ddp: phandle of ddp device which control display data path.
+
+Example:
+
+crtc_main: crtc@...0c000 {
+ compatible = "mediatek,mt8173-crtc-main";
+ interrupts = <GIC_SPI 196 IRQ_TYPE_LEVEL_LOW>;
+ reg = <0 0x1400c000 0 0x1000>, /* OVL0 */

+Mediatek DDP Device
+================================
+
+The Mediatek DDP device control the display data path.

+Mediatek DRM Device
+================================
+
+The Mediatek DRM device is a device needed to list all
+display component nodes that comprise the display subsystem.
+And it list the memory-related interface.
+
+Required properties:
+- compatible: "mediatek,<chip>-drm"
+- larb: Should contain a list of phandles pointing to larb device.
+ larb definitions as defined in
+ Documentation/devicetree/bindings/soc/mediatek/mediatek,smi-larb.txt
+- iommus: required a iommu node
+- connectors: Should contain a list of phandles pointing to connector device.
+ connector device should be one component of this master.
+- crtcs: Should contain a list of phandles pointing to crtc device.
+ crtc device should be one component of this master.
+
+Example:
+
+drm0: drm {
+ compatible = "mediatek,mt8173-drm";
+ larb = <&larb0>;
+ iommus = <&iommu M4U_PORT_DISP_OVL0>;
