Subject: [PATCH 1/7] dt-bindings: dmaengine: qcom: gpi: Allow dma-coherent
Date: Wed, 30 Aug 2023 14:48:40 +0200 [thread overview]
Message-ID: <20230830-topic-8550_dmac2-v1-1-49bb25239fb1@linaro.org> (raw)
In-Reply-To: <20230830-topic-8550_dmac2-v1-0-49bb25239fb1@linaro.org>
On SM8550, the GPI DMA controller is coherent with the CPU.
Allow specifying that.
