Subject: [PATCH v2 1/2] dt-bindings: renesas,rcar-dmac: Add r8a779f0 support
Date: Wed, 22 Dec 2021 20:45:06 +0900	[thread overview]
Message-ID: <20211222114507.1252947-2-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <20211222114507.1252947-1-yoshihiro.shimoda.uh@renesas.com>

Document the compatible value for the Direct Memory Access Controller
blocks in the Renesas R-Car S4-8 (R8A779F0) SoC.

The most visible difference with DMAC blocks on other R-Car SoCs
(except R8A779A0) is the move of the per-channel registers to
a separate register block.
