Subject: [PATCH 7/7] arm64: dts: qcom: sdm845: enable dma for spi
Date: Mon, 11 Jan 2021 20:46:51 +0530	[thread overview]
Message-ID: <20210111151651.1616813-8-vkoul@kernel.org> (raw)
In-Reply-To: <20210111151651.1616813-1-vkoul@kernel.org>

Add dmas property for spi@880000 and pinconf setting so that we can use
dma for this spi device. Also, add iommu properties for qup and spi.
