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