[PATCH v2 00/13] media: stm32: dcmipp: add support for MP2x pixel pipes

[Alain Volmat]

This series add support for the main & aux pixel pipes
available on the MP2x. In addition to the byte pipe
already available, the DCMIPP is able to process two
other streams in parallel, including ISP operations
such as demosaicing, exposure etc, post-processing operations
such as cropping, downscaling and various pixel formats
output.

This series introduces the whole DCMIPP pipelines including
static configuration of the ISP part (such as demosaicing).
Dynamic control of the ISP as well as statistic extraction
part will be added on top of this serie via usage of 2 other
video devices (input & output) for statistics extraction and
dynamic ISP parameter injection.
