Subject: [PATCH v2 00/15] media: stm32: introduction of CSI / DCMIPP for
 STM32MP25

This series introduces the camera pipeline support for the
STM32MP25 SOC.  The STM32MP25 has 3 pipelines, fed from a
single camera input which can be either parallel or csi.

This series adds the basic support for the 1st pipe (dump)
which, in term of features is same as the one featured on
the STM32MP13 SOC.  It focuses on introduction of the
CSI input stage for the DCMIPP, and the CSI specific new
control code for the DCMIPP.
One of the subdev of the DCMIPP, dcmipp_parallel is now
renamed as dcmipp_input since it allows to not only control
the parallel but also the csi interface.
