Subject: [PATCHv2 15/31] ARM: dts: r8a7791: Reference both DMA controllers in QSPI node
Date: Tue, 15 Mar 2016 13:41:52 +0100 [thread overview]
Message-ID: <1458045728-4758-16-git-send-email-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <1458045728-4758-1-git-send-email-niklas.soderlund+renesas@ragnatech.se>
R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.
