[RFC PATCH 3/3] arm64: dts: qcom: shikra: enable WCN SW_CTRL wakeup
From: Linghui Wu
Date: Wed Oct 14 2026 - 08:22:13 EST
Configure the WCN power sequencer SW_CTRL signal as a named wake IRQ and
mark it as a wakeup source. The CQM SOM DTSI is shared by the CQM and CQS
EVKs, while the IQS EVK uses the IQS SOM DTSI.
