Subject: [PATCH v5 1/2] dt-bindings: pci: qcom: Document ddrss_sf_tbu clock for sm8250
Date: Sun, 17 Jan 2021 04:31:13 +0300 [thread overview]
Message-ID: <20210117013114.441973-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210117013114.441973-1-dmitry.baryshkov@linaro.org>
On SM8250 additional clock is required for PCIe devices to access NOC.
Document this requirement in devicetree bindings.
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
Fixes: 458168247ccc ("dt-bindings: pci: qcom: Document PCIe bindings for SM8250 SoC")
