Subject: [PATCH v4 4/5] PCI: qcom: Add SM8250 SoC support
Date: Mon,  5 Oct 2020 15:01:51 +0530	[thread overview]
Message-ID: <20201005093152.13489-5-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20201005093152.13489-1-manivannan.sadhasivam@linaro.org>

The PCIe IP (rev 1.9.0) 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_1_9_0 is the config_sid
callback, which will be added in successive commit.
