Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
stkwebcam, tm6000, vpfe_capture and zr364xx
- saa7146 recovered from staging/deprecated. We opted to give ti a
chance, and, instead of deprecating it, the intention is to write
patches migrating it from VB1 to VB2.
- av7110 returned from staging/deprecated/ to staging/ as we're not
planning on dropping it any time soon
- media controller API has gained experimental support for G_ROUTING
and streams API. No drivers use it right now. We're planning to add
one after -rc1, giving some time to experience the API and eventually
have changes during the next development cycle
- New sensor drivers: imx296, imx415, ov8858
- Atomisp had lots of changes, specially on its sensor's interface,
making atomisp sensor drivers closer to normal sensor drivers
- media controller kAPI has gained some helpers to traverse pipelines
- uvcvideo now better support power line control
- lots of bug fixes, cleanups and driver improvements

The extended - parameters are described by the meye_params structure. - - -MEYEIOC_QBUF_CAPT - Queue a buffer for capture (the buffers must have been - obtained with a VIDIOCGMBUF call and mmap'ed by the - application).
