Hi All,

This patch series aims to add driver support to CRU module found on Renesas
RZ/G2L SoC.

The Camera Data Receiving Unit (CRU) consists of a MIPI CSI-2 block and an
Image Processing block. The Image Processing block can receive video data
received from the external Digital Parallel Interface or MIPI CSI-2 block,
and perform appropriate image processing for each.

More details:
* https://renesas.info/wiki/File:CRU.png
* https://www.renesas.com/document/mah/rzg2l-group-rzg2lc-group-users-manual-hardware-0?language=en&r=1467981

Currently the driver has been tested using yavta and Gstreamer on RZ/G2L
SMARC EVK using the ov5645 sensor on CSI2 interface only.
