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. Signed-off-by:

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. And also, when the call of function vpe_runtime_get() failed, we won't call vpe_runtime_put(). Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails inside vpe_runtime_get().

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:

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.
