2632e7b618 media: venus: firmware: Ignore secure call error on first resume
With the latest cleanup in qcom scm driver the secure monitor
call for setting the remote processor state returns EINVAL when
it is called for the first time and after another scm call
auth_and_reset. The error returned from scm call could be ignored
because the state transition is already done in auth_and_reset.

09e6a7d63e media: allegro: pass buffers through firmware
As we know which buffers are processed by the codec from the address in
the ENCODE_FRAME response, we can queue multiple buffers in the firmware
and retrieve the buffer from the response of the firmware. This enables
the firmware to use the internal scheduling the codec and avoids round
trips through the driver when fetching the next frame.

Remove buffers that have been passed to the firmware from the m2m buffer
queue and put them into a shadow queue for tracking the buffer in the
driver. When we receive a ENCODE_FRAME response from the firmware, get
the buffer from the shadow queue and finish the buffer.

Furthermore, it is necessary to finish the job straight after passing
the buffer to the firmware to allow the V4L2 framework to send further
buffers to the driver.

e74145c233 media: allegro: skip filler data if possible
The driver instructs the firmware to leave some space space in front of
the coded frame data for SPS/PPS data. If the driver receives an IDR, it
writes the SPS/PPS into that free space and fills the rest with filler
data. However, if there is no additional data, the driver can use the
plane offset to skip this space instead of adding filler data.

As the size of the SPS/PPS is only available after writing it, keep the
filler data between the SPS/PPS and the coded frame data.

75a0359f29 media: staging: allegro: fix broken registration of controls
Since commit cc62c74749 ("media: allegro: add missed checks in
allegro_open()") the allegro device does provide v4l2 controls to user
space anymore. The reason is that v4l2_fh_init() initializes
fh->ctrl_handler to vdev->ctrl_handler, which invalidates the previous
driver override of the ctrl_handler.

Therefore, v4l2_fh_init() must be called before the driver overrides the
fh->ctrl_handler with its own handler.

Move the initialization of the fh back to the top, as the initialization
does not does not need to be reverted on errors, but it is enough to
free the channel.

f7b8488bd3 media: imx: imx7-media-csi: Fix video field handling
Commit 4791bd7d6a ("media: imx: Try colorimetry at both sink and
source pads") reworked the way that formats are set on the sink pad of
the CSI subdevice, and accidentally removed video field handling.
Restore it by defaulting to V4L2_FIELD_NONE if the field value isn't
supported, with the only two supported value being V4L2_FIELD_NONE and
V4L2_FIELD_INTERLACED.

490f1ff1e6 media: imx: imx7-media-csi: Remove unneeded register read
The imx7_csi_dma_reflash() function starts by reading the unrelated
register CSI_CSICR18 to then overwrite the read value with a read from
register CSI_CSICR3. This is likely due to a bad copy&paste, and is not
needed. Remove the extraneous read from register CSI_CSICR18.

Enable filtering based on CSI-2 data type. Otherwise sources that send
multiple data types (such as sensors that send embedded data) will not
be properly supported. They will both result in additional non-image
lines being captured, and in the receiver being confused as it doesn't
resynchronise on vsync.
