Subject: [PATCH 03/11] dmaengine: dw-axi-dmac: remove unnecessary axi_dma_enable() calling
Date: Tue, 14 Mar 2023 01:04:42 +0800 [thread overview]
Message-ID: <20230313170450.897-4-jszhang@kernel.org> (raw)
In-Reply-To: <20230313170450.897-1-jszhang@kernel.org>
The dma is enabled, I.E runtime resumed during chan allocation, and
is disable, I.E runtime suspended during chan free. So when starting
xfer, we are sure the dma is enabled.
