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
