The file handle is not yet added in the vfd list. So no need to call v4l2_fh_del(&ctx->fh) if it fails to create controls. Signed-off-by:

Setting GPIOs during probe causes null pointer deference when GPIOLIB was not selected by Kconfig. Initialize driver private field before calling set gpios. It is regressing bug since 4.9. Fixes: 07fdf7d9 ("[media] cxd2820r: add I2C driver bindings") Reported-by:

The VDOA is able to transform the NV12 custom macroblock tiled format of the CODA to YUYV format. If and only if the VDOA is available, the driver can also provide YUYV support. While the driver is configured to produce YUYV output, the CODA must be configured to produce NV12 macroblock tiled frames and the VDOA must transform the intermediate result into the final YUYV output.

If the CODA driver is configured to produce NV12 output and the VDOA is available, the VDOA can be used to transform the custom macroblock tiled format to a raster-ordered format for scanout. In this case, set the output format of the CODA to the custom macroblock tiled format, disable the rotator, and use the VDOA to write to the v4l2 buffer. The VDOA is synchronized with the CODA to always un-tile the frame that the CODA finished in the previous run. Signed-off-by:

display_idx refers to the frame that will be returned in the next round. The currently processed frame is ctx->display_idx and errors should be reported for this frame. Signed-off-by:

In order to make the VDOA work correctly, the CODA must produce frames in tiled format. Print this information in the debug output. Also print the color format in fourcc instead of the numeric value. Signed-off-by:

Video capture subdevs may be over I2C and may sleep during xfer, so we cannot do IRQ-disabled locking when calling the subdev. The IRQ-disabled locking is meant to protect the DMA queue list throughout the rest of the driver, so update the locking in [start|stop]_streaming to protect just this list, and update the irqlock comment to reflect what it actually protects.
