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

[ Aisheng: update to new kernel version accordingly ]
|
|
[ Aisheng: split IPU changes out of imx-drm-core change ]
