[v5,3/8] media: mediatek: vcodec: Refactor venc power manage function

Commit Message

Irui Wang July 29, 2022, 3:51 a.m. UTC

The args "struct mtk_vcodec_dev *" doesn't appropriate for init_clk
functions because of sub-devices, sub-devices will init their own
"pm/clk" instead, so refactor the pm function with args
"platform_device *" and "mtk_vcodec_pm*".
