Subject: [PATCH v3 6/7] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers
Date: Tue, 10 Mar 2020 14:55:41 +0200	[thread overview]
Message-ID: <20200310125542.5939-7-olteanv@gmail.com> (raw)
In-Reply-To: <20200310125542.5939-1-olteanv@gmail.com>

From: Vladimir Oltean <vladimir.oltean@nxp.com>

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.
