Merge tag 'media/v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - New sensor driver: imx219

 - Support for some new pixelformats

 - Support for Sun8i SoC

 - Added more codecs to meson vdec driver

 - Prepare for removing the legacy usbvision driver by moving it to
   staging. This driver has issues and use legacy core APIs. If nobody
   steps up to address those, it is time for its retirement.

 - Several cleanups and improvements on drivers, with the addition of
   new supported boards

+description: |-
+  The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
+  with an active array size of 3280H x 2464V. It is programmable through
+  I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+  Image data is sent through MIPI CSI-2, which is configured as either 2 or
+  4 data lanes.

+The device node must contain one 'port' child node per device physical input

-Required Endpoint Properties for parallel synchronization:

-- field-even-active: field signal level during the even field data
-  transmission. Must be <0>.
+The device node must contain at least one sink port and the src port. Each input
+port must be linked to an endpoint defined in [1]. The port/connector layout is
