Subject: [PATCH 11/16] ARM: dts: at91: sama5d2: Add DMA bindings for the SPI and I2C flx0 functions
Date: Thu, 14 May 2020 05:03:14 +0000	[thread overview]
Message-ID: <20200514050301.147442-12-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20200514050301.147442-1-tudor.ambarus@microchip.com>

From: Tudor Ambarus <tudor.ambarus@microchip.com>

Spare boards of duplicating the DMA bindings. Describe the flx0
DMA bindings in the SoC dtsi. Users that don't want to use DMA
for their flexcom functions have to overwrite the flexcom DMA
bindings in their board device tree.
