Subject: [PATCH v5 11/12] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers
Date: Wed, 18 Mar 2020 02:16:02 +0200 [thread overview]
Message-ID: <20200318001603.9650-12-olteanv@gmail.com> (raw)
In-Reply-To: <20200318001603.9650-1-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.
