Subject: [PATCH v3 05/10] PCI: qcom: Add ddrss_sf_tbu flag
Date: Sat, 11 Dec 2021 05:17:53 +0300	[thread overview]
Message-ID: <20211211021758.1712299-6-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20211211021758.1712299-1-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.
