Currently, support for RK3288 and RK3399 is included. The hardware produces a Raw JPEG format (i.e. works as a JPEG accelerator). It requires quantization tables provided by the application, and uses standard huffman tables, as recommended by the JPEG specification. In order to support this, the series introduces a new pixel format, and a new pair of controls, V4L2_CID_JPEG_{LUMA,CHROMA}_QUANTIZATION allowing userspace to specify the quantization tables. Userspace is then responsible to add the required headers and tables to the produced raw payload, to produce a JPEG image.
