Subject: [PATCH 1/2] dt-bindings: ufs: qcom: allow 'dma-coherent' property
Date: Mon, 5 Dec 2022 11:08:36 +0100 [thread overview]
Message-ID: <20221205100837.29212-2-johan+linaro@kernel.org> (raw)
In-Reply-To: <20221205100837.29212-1-johan+linaro@kernel.org>
UFS controllers may be cache coherent and must be marked as such in the
devicetree to avoid data corruption.
This is specifically needed on recent Qualcomm platforms like SC8280XP.
