[v6,00/17] media: rzg2l-cru: Add support for RZ/G3E (CSI2, CRU)

Message

Tommaso Merciai April 10, 2025, 8:12 a.m. UTC

Dear All,

In preparation of supporting the CRU/CSI2 IPs found into the Renesas RZ/G3E
SoC, this series adds driver/dt-bindings support.
This adds also some minor fixes into rzg2l-csi2 and rzg2l-core drivers.

The series was tested in an out of tree branch with the following hw pipeline:

ov5645 image sensor (Coral Camera) -> rzg3e CSI2 -> rzg3e CRU
imx219 image sensor (Pi PiNoir Camera Module V2.1) -> rzg3e CSI2 -> rzg3e CRU

base commit: 7702d0130dc00 (tag: next-20250408)
