C-PHY doesn't use a clock lane, hence the test for the clock lane when there isn't one is faulty. Rework the test for the conflicting clock lane. Signed-off-by:

If the v4l2 controls are set up for autofoo/foo-type handling by calling v4l2_ctrl_auto_cluster() with the last set_volatile argument setting true, each non-auto control doesn't need to be flagged V4L2_CTRL_FLAG_VOLATILE.

Setting the value of the V4L2_CID_VFLIP control is currently ignored. Because V4L2_CID_HFLIP and V4L2_CID_VFLIP are independently controlled in s_ctrl() but these controls belong to the same cluster and the first control is V4L2_CID_HFLIP. Fix it by not clustering these controls. Also correct erroneous updating register bit for vertical flip.

If the requested framesize by VIDIOC_SUBDEV_S_FMT is larger than supported framesizes, it causes an out of bounds array access and the resulting framesize is unexpected.

Some displays pull down the HPD when in standby, but CEC is still active and the display can be woken up by sending an Image View On or Text View On CEC command. The CEC specification doesn't tell you what the initiator should be for such a command (without a HPD it's unclear if the CEC adapter can claim a logical address). This patch allows any initiator value when there is no HPD for the Image/Text View On commands and for the Ping command. Signed-off-by:

Due to limitations in gpiolib it was impossible to disable the interrupt of an input gpio and then switch it to gpio output and drive it. The only way to achieve that was to free the interrupt first, then switch the direction. When going back to gpio input and using interrupts to read the gpio pin you had to request the irq again. This limitation was lifted in gpiolib in kernel 4.20, but the cec-gpio driver was still using the old workaround implementation. This patch updates the cec-gpio driver to just enable and disable the irq. Signed-off-by:

The cec device node can be used right after it was created, but that leaves a race condition where the device was created, but devnode->registered was still false. So an ioctl() would result in an error. So set it to true before calling cdev_device_add() and to false again if cdev_device_add returned an error. Signed-off-by:

actual_length != wlen is the only error path which does not generate an error message. Adding an error message here allows to report a more specific error and to remove the error reporting from the call sites. Also clean up the error paths - in case of an error, the remaining code is skipped, and ret is returned. Skip setting ret and return immediately (no cleanup necessary). Signed-off-by:

In case the sensor refuses to set the format, avoid printing the error message that no compatible format was found. This means that the try_fmt will be less verbose. The error will be printed only if really a format cannot be found. Some application try all possible formats in a row (gstreamer e.g.) which will flood the console with error messages until a working one is found. Signed-off-by:

This adds support for the 'button' control DO_WHITE_BALANCE This feature will enable the ISC to compute the white balance coefficients in a one time shot, at the user discretion. This can be used if a color chart/grey chart is present in front of the camera. The ISC will adjust the coefficients and have them fixed until next balance or until sensor mode is changed. This is particularly useful for white balance adjustment in different lighting scenarios, and then taking photos to similar scenery. The old auto white balance stays in place, where the ISC will adjust every 4 frames to the current scenery lighting, if the scenery is approximately grey in average, otherwise grey world algorithm fails. One time white balance adjustments needs streaming to be enabled, such that capture is enabled and the histogram has data to work with. Histogram without capture does not work in this hardware module. To start the one time white balance procedure: v4l2-ctl --set-ctrl=do_white_balance=1 This feature works only if the sensor is streaming RAW data, as the hardware supports a histogram only for RAW bayer components. If the auto white balance is enabled, do_white_balance does nothing. If the streaming is disabled, or the sensor does not output RAW data, the control is inactive. User controls now include the do_white_balance ctrl: User Controls brightness 0x00980900 (int) : min=-1024 max=1023 step=1 default=0 value=0 flags=slider contrast 0x00980901 (int) : min=-2048 max=2047 step=1 default=256 value=256 flags=slider white_balance_automatic 0x0098090c (bool) : default=1 value=0 do_white_balance 0x0098090d (button) : flags=write-only, execute-on-write gamma 0x00980910 (int) : min=0 max=2 step=1 default=2 value=2 flags=slider Signed-off-by: -

Reworked auto white balance feature (awb) to cope with all four channels. Implemented stretching and grey world algorithms. Using the histogram, the ISC will auto adjust the white balance during frame captures. Because each histogram needs a frame, it will take 4 frames for one adjustment. When the gains were updated by previous code, the registers for the gains were updated only on new streaming start. Now, after each full histogram the registers are updated with new gains. Also, on previous code, if the streaming stopped but not all 3 histograms finished, a new histogram was started either way. This used to lead to an error "timeout to update profile" when streaming was stopped. According to the hardware, histogram can only work together with the capture, not independently. Signed-off-by:
