[PATCH 2/3] media: mtk-jpegenc: use component framework to manage jpg HW
kyrie.wu
kyrie.wu at mediatek.com
Tue Jun 22 23:05:49 PDT 2021
Mtk jpeg encoder has several hardware, one HW may register a device
node; use component framework to manage jpg HW device node,
in this case, one device node could represent all jpg HW.
