Subject: [PATCH 03/18] arm64: dts: qcom: sdm845: Fix PCIe wake GPIO polarity
Date: Thu, 21 May 2026 18:36:36 +0530 [thread overview]
Message-ID: <20260521-wake-v1-3-d822567be258@oss.qualcomm.com> (raw)
In-Reply-To: <20260521-wake-v1-0-d822567be258@oss.qualcomm.com>
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.
