[PATCH v2 05/12] drm/mediatek: Move regs info from struct mtk_ddp_comp to sub driver private data
Chun-Kuang Hu
chunkuang.hu at kernel.org
Thu Dec 10 16:10:43 UTC 2020
From: CK Hu <ck.hu at mediatek.com>
Some ddp component exist in both display path and other path, so data
belonged to sub driver should be moved into sub driver private data so it
could be used for multiple path. regs info is one of sub driver data, so
move it.
