4 Subject: [PATCH] drm/imx: Extract IPUv3 specific KMS functions to ipuv3-kms.c
5 (part 1)
6
7 Since we want to add i.MX DPU support into imx-drm, the imx-drm core
8 driver should be no more IPUv3 specific. Let's make imx-drm more generic
9 and extract IPUv3 specific KMS functions to ipuv3-kms.c.

13 [ Aisheng: split IPU changes out of imx-drm-core change ]
