title: Renesas RZ/G2L (and alike SoC's) MIPI CSI-2 receiver
maintainers:
- Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
description:
The CSI-2 receiver device provides MIPI CSI-2 capabilities for the Renesas RZ/G2L
(and alike SoCs). MIPI CSI-2 is part of the CRU block which is used in conjunction
with the Image Processing module, which provides the video capture capabilities.
