Subject: [PATCH v2 5/6] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers
Date: Mon,  9 Mar 2020 23:07:54 +0200	[thread overview]
Message-ID: <20200309210755.6759-6-olteanv@gmail.com> (raw)
In-Reply-To: <20200309210755.6759-1-olteanv-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Vladimir Oltean <vladimir.oltean-3arQi8VN3Tc@public.gmane.org>

LS1028A has a functional connection to the eDMA module. Even if the
spi-fsl-dspi.c driver is not using DMA for LS1028A now, define the slots
in the DMAMUX for connecting the eDMA channels to the 3 DSPI
controllers.

Signed-off-by: Vladimir Oltean <vladimir.oltean-3arQi8VN3Tc@public.gmane.org>
