-Etnaviv DRM master device
-=========================
-
-The Etnaviv DRM master device is a virtual device needed to list all
-Vivante GPU cores that comprise the GPU subsystem.
-
-Required properties:
-- compatible: Should be one of
- "fsl,imx-gpu-subsystem"
- "marvell,dove-gpu-subsystem"
-- cores: Should contain a list of phandles pointing to Vivante GPU devices
-
-example:
-
-gpu-subsystem {
- compatible = "fsl,imx-gpu-subsystem";
- cores = <&gpu_2d>, <&gpu_3d>;
-};
