[PATCH 16/18] arm64: dts: qcom: sa8540p-ride: Fix PCIe wake GPIO polarity

From: Krishna Chaitanya Chundru

Date: Thu May 21 2026 - 09:23:37 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.
