Subject: [linux][PATCH 4/6] ARM: dts: at91: sam9x60: Add DMA bindigs for the flexcom nodes
Date: Wed, 7 Sep 2022 14:50:52 +0530	[thread overview]
Message-ID: <20220907092054.29915-5-Hari.PrasathGE@microchip.com> (raw)
In-Reply-To: <20220907092054.29915-1-Hari.PrasathGE@microchip.com>

Add dma bindings for flexcom nodes in the soc dtsi file. Users those who
don't wish to use the DMA function for their flexcom functions can
overwrite the dma bindings in the board device tree file.
