Subject: [PATCH v2 06/18] arm64: dts: qcom: sm8250: Fix PCIe WAKE# GPIO polarity
Date: Thu, 17 Sep 2026 17:24:14 +0530 [thread overview]
Message-ID: <20260917-root_port-v2-6-0d627d0856d5@oss.qualcomm.com> (raw)
In-Reply-To: <20260917-root_port-v2-0-0d627d0856d5@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.
