Merge tag 'media/v6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- New sensor drivers: gc05a2, gc08a3 and imx283
- New serializer/deserializer drivers: max96714 and max96717
- New JPEG encoder driver: e5010
- Support for Raspberry Pi PiSP Backend (BE) ISP driver
- Old documentation for av7110 driver removed, as a new version was
added as Documentation/userspace-api/media/dvb/legacy*.rst
- atompisp: Linux firmwares are now available, so drop firmware-related
task from TODO and update firmware logic
- The imx258 driver has gained several improvements
- wave5 driver has gained support for HEVC decoding
- em28xx gained support for MyGica UTV3
- av7110 budget-patch driver removed
- Lots of other cleanups, improvements and fixes
