Subject: [PATCH v2 4/5] PCI: qcom: Add SM8250 SoC support
Date: Wed, 30 Sep 2020 20:39:24 +0530 [thread overview]
Message-ID: <20200930150925.31921-5-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20200930150925.31921-1-manivannan.sadhasivam@linaro.org>
The PCIe IP on SM8250 SoC is similar to the one used on SDM845. Hence
the support is added reusing the members of ops_2_7_0. The key
difference between ops_2_7_0 and ops_sm8250 is the config_sid callback,
which will be added in successive commit.
