Subject: [PATCH v4 2/8] clk: qcom: gcc-ipq9574: Add PCIe pipe clocks
Date: Tue, 30 Apr 2024 23:07:53 -0500 [thread overview]
Message-ID: <20240501040800.1542805-12-mr.nuke.me@gmail.com> (raw)
In-Reply-To: <20240501040800.1542805-1-mr.nuke.me@gmail.com>
The IPQ9574 has four PCIe "pipe" clocks. These clocks are required by
PCIe PHYs. Port the pipe clocks from the downstream 5.4 kernel.
