Daniel ScallyandHans Verkuil 8d0bbed21e media: uapi: Add controls for Mali-C55 ISP
Add definitions and documentation for the custom control that will
be needed by the Mali-C55 ISP driver. This will be a read only
bitmask of the driver's capabilities, informing userspace of which
blocks are fitted and which are absent.

Benjamin MugnierandHans Verkuil 15765ff714 media: i2c: vgxy61: Fix device name
Rename 'st-vgxy61' to 'vgxy61', dropping the vendor prefix to follow the
same naming scheme as the vast majority of device drivers.
The device tree binding does not fall into binding rename exceptions and
therefore must not be changed. Keep its legacy name.

Laurent PinchartandHans Verkuil 0d9e32a807 media: uapi: Add controls for the THP7312 ISP
The THP7312 is an external ISP from THine. As such, it implements a
large number of parameters to control all aspects of the image
processing. Many of those controls are already standard in V4L2, but
some are fairly device-specific.

Reserve a range of 32 controls for the device. The driver will implement
4 device-specific controls to start with, define and document them. 28
additional device-specific controls should be enough for future
development.

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 meye driver does not use the vb2 framework for streaming
video, instead it implements this in the driver. This is error prone,
and nobody stepped in to convert this driver to that framework.

The hardware is very old, so the decision was made to remove it
altogether.
