[PATCH v3 3/3] arm64: dts: qcom: shikra: enable WCN SW_CTRL
From: Linghui Wu
Date: Mon Oct 19 2026 - 05:40:22 EST
The WCN3988 SW_CTRL signal can wake the application processor on the
Shikra CQM, CQS and IQS EVKs.
Mark the WCN power sequencer as a wakeup source so the driver uses the
existing SW_CTRL GPIO as a dedicated wake IRQ.
