Subject: [PATCH] arm64: dts: qcom: shikra: Add RF_CLK2 clock to wcn3988-pmu nodes
Date: Tue, 20 Oct 2026 21:08:52 +0800 [thread overview]
Message-ID: <20261020130852.3049639-1-cheng.jiang@oss.qualcomm.com> (raw)
The WCN3988 on the Shikra SoMs takes its reference clock from the RPM
RF_CLK2 clock. It is not described in the device tree, so pwrseq-qcom-wcn
finds no clock to enable and RF_CLK2 stays off, leaving Bluetooth unable
to come up.
Describe the clock on the wcn3988-pmu nodes in both SoM dtsi files so
pwrseq-qcom-wcn enables it as part of the WCN3988 power-on sequence.
