[PATCHv5 1/5] media: v4l UAPI: add ROI selection targets

From: Sergey Senozhatsky
Date: Sat May 01 2021 - 04:20:23 EST


UVC 1.5 requires Region Of Interest control to implement
GET_CUR, GET_DEF, GET_MIN and GET_MAX requests. This patch
adds new V4L2 selection API targets that will implement
those ROI requests.
