Subject: [RFC PATCH v2 0/4] Add driver for Renesas RZ/G2L CRU module

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://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.

Patches are dependent on millstream series [0] and subdev active state series [1].
