Browse Source 
Pull media updates from Mauro Carvalho Chehab:

 - Lots of improvement at atomisp driver, which is starting to look in
   good shape

 - Mediatek vcodec driver has gained support for av1 and hevc stateless
   codecs

 - New sensor driver: ov01a10

 - verisilicon driver has gained AV1 entropy helpers

 - tegra-video has gained support for Tegra20 parallel input

 - dvb core has gained an extra property to better support DVB-S2X

 - as usual, lots of cleanups, fixes and improvements on media drivers

The function returns a non-zero value if it succeeded getting the power count or
runtime PM was disabled, in either of which cases the driver may proceed to
access the device.
Rotation, orientation and flipping
----------------------------------
Some systems have the camera sensor mounted upside down compared to its natural
mounting rotation. In such cases, drivers shall expose the information to
userspace with the :ref:`V4L2_CID_CAMERA_SENSOR_ROTATION
<v4l2-camera-sensor-rotation>` control.
Sensor drivers shall also report the sensor's mounting orientation with the
:ref:`V4L2_CID_CAMERA_SENSOR_ORIENTATION <v4l2-camera-sensor-orientation>`.
Use ``v4l2_fwnode_device_parse()`` to obtain rotation and orientation
information from system firmware and ``v4l2_ctrl_new_fwnode_properties()`` to
register the appropriate controls.
Sensor drivers that have any vertical or horizontal flips embedded in the
register programming sequences shall initialize the V4L2_CID_HFLIP and
V4L2_CID_VFLIP controls with the values programmed by the register sequences.
The default values of these controls shall be 0 (disabled). Especially these
controls shall not be inverted, independently of the sensor's mounting
rotation.
