Subject: [PATCH 0/8] media: rzg2l-cru: Document RZ/G3E (CSI2, CRU)
Dear All,
In preparation of supporting the CRU/CSI2 IPs found into the Renesas RZ/G3E
SoC, this series adds support for CRU0 clocks and resets, adds also dt-bindings
for CRU and CSI2 IP and adds some fixes into rzg2l-csi2 and rzg2l-core drivers.
The series was tested in a out of tree branch with the following media
pipeline:
imx219 -> rzg3e CSI2 -> rzg3e CRU
Some logs:
