Merge tag 'media/v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - the usbvision driver was dropped from staging - the Zoran driver were re-added at staging. It gained lots of improvements, and was converted to use videobuf2 API - a new virtual driver (vidtv) was added in order to allow testing the digital TV framework and APIs - the media uAPI documentation gained a glossary with commonly used terms, helping to simplify some parts of the docs - more cleanups at the atomisp driver - Mediatek VPU gained support for MT8183 - added support for codecs with supports doing colorspace conversion (CSC) - support for CSC API was added at vivid and rksip1 drivers - added a helper core support and uAPI for better supporting H.264 codecs - added support for Renesas R8A774E1 - use the new SPDX GFDL-1.1-no-invariants-or-later license on media uAPI docs, instead of a license text - Venus driver has gained VP9 codec support - lots of other cleanups and driver improvements * tag 'media/v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (555 commits) media: dvb-frontends/drxk_hard.c: fix uninitialized variable warning media: tvp7002: fix uninitialized variable warning media: s5k5baf: drop 'data' field in struct s5k5baf_fw media: dt-bindings: media: venus: Add an optional power domain for perf voting media: rcar-vin: rcar-dma: Fix setting VNIS_REG for RAW8 formats media: staging: rkisp1: uapi: Do not use BIT() macro media: v4l2-mem2mem: Fix spurious v4l2_m2m_buf_done media: usbtv: Fix refcounting mixup media: zoran.rst: place it at the right place this time media: add Zoran cardlist media: admin-guide: update cardlists media: siano: rename a duplicated card string media: zoran: move documentation file to the right place media: atomisp: fixes build breakage for ISP2400 due to a cleanup media: zoran: fix mixed case on vars media: zoran: get rid of an unused var media: zoran: use upper case for card types media: zoran: fix sparse warnings media: zoran: fix smatch warning media: zoran: update TODO ...
