Subject: [PATCH 1/2] dt-bindings: dma: allwinner,sun50i-a64-dma: Add R40 compatible
Date: Tue, 25 Aug 2020 12:00:29 +0200	[thread overview]
Message-ID: <20200825100030.1145356-2-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20200825100030.1145356-1-jernej.skrabec@siol.net>

R40 has DMA engine which is basically the same as that in A64, with only
known difference being number of request sources and number of channels.

Add compatible for it.
