[PATCH v1] arm64: dts: qcom: qcs6490-rb3gen2-industrial-mezzanine: Add PCIe wake GPIO

From: Hongcheng Zhang

Date: Mon Sep 14 2026 - 21:23:28 EST


The QCS6490-based RB3 Gen 2 Industrial Kit cannot wake from suspend via
PCIe Wake-on-WLAN.

Add the wake-gpios property to the PCIe port so the WLAN wake signal is
propagated as a system wakeup source.
