pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, causing incorrect ref count if pm_runtime_put_noidle() is not called in error handling paths. Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails. Fixes: 6eaafbdb ("[media] v4l: rcar-fcp: Keep the coding style consistent") Signed-off-by:

The Documentation/DMA-API-HOWTO.txt states that dma_map_sg returns the numer of the created entries in the DMA address space. However the subsequent calls to dma_sync_sg_for_{device,cpu} and dma_unmap_sg must be called with the original number of entries passed to dma_map_sg. The sg_table->nents in turn holds the result of the dma_map_sg call as stated in include/linux/scatterlist.h. Adapt the code to obey those rules. While touching this code, update it to use the modern DMA_FROM_DEVICE definitions. Signed-off-by: -

The resizer calls the enum_mbus_code cb on the source pad of the isp entity since they support the same formats. The only difference is that the isp entity allows setting the quantization and sets the flag V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION. The resizer should therefore set the flags to 0. Signed-off-by:

The isp entity has hardware support to force full range quantization for YUV formats. Use the subdev CSC API to allow userspace to set the quantization for YUV formats on the isp entity. - The flag V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION is set for YUV formats during enumeration of the isp formats on the source pad. - The full quantization is set on YUV formats if userspace asks it on the isp entity using the flag V4L2_MBUS_FRAMEFMT_SET_CSC. On the capture and the resizer, the quantization is read-only and always set to the default quantization. Signed-off-by:

This patch extends the CSC API in video devices to be supported also on sub-devices. The flag V4L2_MBUS_FRAMEFMT_SET_CSC set by the application when calling VIDIOC_SUBDEV_S_FMT ioctl. The flags: V4L2_SUBDEV_MBUS_CODE_CSC_COLORSPACE, V4L2_SUBDEV_MBUS_CODE_CSC_XFER_FUNC, V4L2_SUBDEV_MBUS_CODE_CSC_YCBCR_ENC/V4L2_SUBDEV_MBUS_CODE_CSC_HSV_ENC V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION are set by the driver in the VIDIOC_SUBDEV_ENUM_MBUS_CODE ioctl. New 'flags' fields were added to the structs v4l2_subdev_mbus_code_enum, v4l2_mbus_framefmt which are borrowed from the 'reserved' field The patch also replaces the 'ycbcr_enc' field in 'struct v4l2_mbus_framefmt' with a union that includes 'hsv_enc' Signed-off-by:

The CSC API (Colorspace conversion) allows userspace to try to configure the colorspace, transfer function, Y'CbCr/HSV encoding and the quantization for capture devices. This patch adds support to the CSC API in vivid. Using the CSC API, userspace is allowed to do the following: - Set the colorspace. - Set the xfer_func. - Set the ycbcr_enc function for YUV formats. - Set the hsv_enc function for HSV formats - Set the quantization for YUV and RGB formats.

For video capture it is the driver that reports the colorspace, transfer function, Y'CbCr/HSV encoding and quantization range used by the video, and there is no way to request something different, even though many HDTV receivers have some sort of colorspace conversion capabilities. For output video this feature already exists since the application specifies this information for the video format it will send out, and the transmitter will enable any available CSC if a format conversion has to be performed in order to match the capabilities of the sink. For video capture we propose adding new v4l2_pix_format flag: V4L2_PIX_FMT_FLAG_SET_CSC. The flag is set by the application, the driver will interpret the colorspace, xfer_func, ycbcr_enc/hsv_enc and quantization fields as the requested colorspace information and will attempt to do the conversion it supports. Drivers set the flags V4L2_FMT_FLAG_CSC_COLORSPACE, V4L2_FMT_FLAG_CSC_XFER_FUNC, V4L2_FMT_FLAG_CSC_YCBCR_ENC/V4L2_FMT_FLAG_CSC_HSV_ENC, V4L2_FMT_FLAG_CSC_QUANTIZATION, in the flags field of the struct v4l2_fmtdesc during enumeration to indicate that they support colorspace conversion for the respective field. Drivers do not have to actually look at the flags. If the flags are not set, then the fields 'colorspace', 'xfer_func', 'ycbcr_enc/hsv_enc', and 'quantization' are set to the default values by the core, i.e. just pass on the received format without conversion.

If poll() is called on a m2m device with the EPOLLOUT event after the last buffer of the CAPTURE queue is dequeued, any buffer available on OUTPUT queue will never be signaled because v4l2_m2m_poll_for_data() starts by checking whether dst_q->last_buffer_dequeued is set and returns EPOLLIN in this case, without looking at the state of the OUTPUT queue.
