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
