2020-09-26media: pci: fix common ALSA DMA-mapping related codesMarek Szyprowski
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.

2020-09-26media: v4l2: add support for colorspace conversion API (CSC) for video captureDafna Hirschfeld
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.

buffer on encoding" This reverts commit 81735ecb62f882853a37a8c157407ec4aed44fd0. The hardware needs data to follow the previous alignment, so this extra space was not superfluous after all. Besides, this also made v4l2-compliance's G_FMT and S_FMT tests regress.

Firmwares for encoders newer than MT8173 will include an ABI version number in their initialization ack message. Add the capacity to manage it and make initialization fail if the firmware ABI is of a version that we don't support. For MT8173, this ABI version field is reserved and thus undefined ; thus ignore it on this chip. There should only be one firmware version available for it anyway.

When adding the support for TBF offload, the improper command version was added even though the command format is for the V2 of dpni_set_tx_shaping(). This does not affect the functionality of TBF since the only change between these two versions is the addition of the exceeded parameters which are not used in TBF.
