Subject: [PATCH v3 4/7] PCI: qcom: Add support for IPQ9574
Date: Mon, 15 Apr 2024 13:20:49 -0500 [thread overview]
Message-ID: <20240415182052.374494-5-mr.nuke.me@gmail.com> (raw)
In-Reply-To: <20240415182052.374494-1-mr.nuke.me@gmail.com>
Add support for the PCIe on IPQ9574. The main difference from ipq6018
is that the "iface" clock is not necessarry. Add a special case in
qcom_pcie_get_resources_2_9_0() to handle this.
