Merge tag 'media/v5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:
 "The rockship rkisp1 driver will be promoted from staging in 5.11.

  While not too late, do a few uAPI changes which are needed to better
  support its functionalities"

* tag 'media/v5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  media: rockchip: rkisp1: extend uapi array sizes
  media: rockchip: rkisp1: carry ip version information
  media: rockchip: rkisp1: reduce number of histogram grid elements in uapi
  media: rkisp1: stats: mask the hist_bins values
  media: rkisp1: stats: remove a wrong cast to u8
  media: rkisp1: uapi: change hist_bins array type from __u16 to __u32

@ -13,6 +13,22 @@ This file documents the driver for the Rockchip ISP1 that is part of RK3288
and RK3399 SoCs. The driver is located under drivers/staging/media/rkisp1
and uses the Media-Controller API.
Revisions
=========
There exist multiple smaller revisions to this ISP that got introduced in
later SoCs. Revisions can be found in the enum :c:type:`rkisp1_cif_isp_version`
in the UAPI and the revision of the ISP inside the running SoC can be read
in the field hw_revision of struct media_device_info as returned by
ioctl MEDIA_IOC_DEVICE_INFO.
Versions in use are:
- RKISP1_V10: used at least in rk3288 and rk3399
- RKISP1_V11: declared in the original vendor code, but not used
- RKISP1_V12: used at least in rk3326 and px30
- RKISP1_V13: used at least in rk1808
