Subject: [PATCH] media: dt-bindings: media: renesas,vin: Add r8a779a0 support
Date: Tue, 13 Apr 2021 19:38:10 +0200	[thread overview]
Message-ID: <20210413173810.2561909-1-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 16 VIN
instances. The VIN instances are also connected to a new IP the R-Car
ISP Channel Selector.
