Message

Add support for RGB formats in rkisp1, (currently only RGB565 is correctly captured)
The patchset is rebased on top of patch
"media: staging: rkisp1: cap: remove field fmt_type from struct rkisp1_capture_fmt_cfg"

patches summary:

patch 1: fix a redundant call to v4l2_format_info in the resizer code
patch 2: fix a bug that changes the default hdiv,vdiv in the resizer scale for RGB formats.
This bug changes the YUV ratios from 4:2:2 to 4:4:4 and the capture for RGB times out
patch 3: removes the restriction in the validation function of the capture that forces the
mbus encoding to be the same as the capture encoding. This is because for RGB formats
the mbus format should be MEDIA_BUS_FMT_YUYV8_2X8

Dafna Hirschfeld (3):
  media: staging: rkisp1: rsz: get the capture format info from the
    capture struct
  media: staging: rkisp1: rsz: change (hv)div only if capture format is
    YUV
  media: staging: rkisp1: cap: enable RGB capture format with YUV media
    bus
