[PATCH 18/34] arm64: dts: qcom: sa8540p-ride: Fix PCIe wake GPIO polarity
From: Krishna Chaitanya Chundru
Date: Thu Sep 10 2026 - 09:45:05 EST
The PCIe WAKE# signal is active-low as defined in the PCIe Base
Specification. Fix the wake-gpios polarity by using GPIO_ACTIVE_LOW
instead of GPIO_ACTIVE_HIGH.
