Subject: [PATCH v2 10/11] PCI: qcom: Add ddrss_sf_tbu flag
Date: Fri, 4 Feb 2022 17:46:44 +0300 [thread overview]
Message-ID: <20220204144645.3016603-11-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220204144645.3016603-1-dmitry.baryshkov@linaro.org>
Qualcomm PCIe driver uses compatible string to check if the ddrss_sf_tbu
clock should be used. Since sc7280 support has added flags, switch to
the new mechanism to check if this clock should be used.
