From dd12fa6978a1c9eb76274dc4e27f91d7c77727b2 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Wed, 18 Mar 2020 02:16:02 +0200 Subject: [PATCH] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers 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.
