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.
v1 -> v2:
* Dropped media prefix from subject
* Renamed node name csi20 -> csi
* Used 4 spaces for indentation in example node
* Dropped reset-names and interrupt-names properties
* Dropped oneOf from compatible
* Included RB tags from Laurent
* Marked port0/1 as required for cru node
* Sorted Kconfig select
* Prefixed generic names for struct/variables with rzg2_csi2
* Dropped unnecessary checks for remote source
* Dropped exporting functions
* Moved lane validation to probe
* Split up rzg2l_csi2_dphy_setting() and rzg2l_csi2_mipi_link_setting()
* Used rzg2l_csi2_write() wherever possible
* Dropped stream_count/lock members from csi2 struct
* Used active subdev state instead of manually storing format in driver
* Implemented init_cfg/enum_frame_size/enum_mbus_code callbacks
* Dropped check for bus_type of remote source
* Switched to manually turning ON/OFF the clocks instead of pm_runtime so that
the mipi/dhpy initialization happens as per the HW manual
* Hardcoded VC0 usage for now as streams API is under development
