Subject: [PATCH 3/3] PCI: qcom: Add sc8180x compatible
Date: Sat, 24 Jul 2021 21:00:38 -0700 [thread overview]
Message-ID: <20210725040038.3966348-4-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20210725040038.3966348-1-bjorn.andersson@linaro.org>
The SC8180x platform comes with 4 PCIe controllers, typically used for
things such as NVME storage or connecting a SDX55 5G modem. Add a
compatible for this, that just reuses the 1.9.0 ops.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
