Subject: [PATCH v2] media: dt-bindings: media: renesas,vin: Add r8a779a0 support
Date: Tue, 11 May 2021 16:33:32 +0200
Message-ID: <20210511143332.3469877-1-niklas.soderlund+renesas@ragnatech.se> (raw)

Document support for the VIN module in the Renesas V3U (r8a779a0) SoC.
The V3U is different from other SoCs as it have 32 instead of 8 (most of
Gen3) or 16 (V3H) VIN instances. The VIN instances are also connected to
a new IP the R-Car ISP Channel Selector.
