Subject: [PATCH 01/34] ARM: dts: qcom: sdx55: Fix PCIe wake GPIO polarity
Date: Thu, 10 Sep 2026 18:58:50 +0530	[thread overview]
Message-ID: <20260910-root_port-v1-1-90a252ddbbfa@oss.qualcomm.com> (raw)
In-Reply-To: <20260910-root_port-v1-0-90a252ddbbfa@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.
