Subject: [PATCH v2 00/18] arm64: dts: qcom: Fix wake-gpios polarity
Date: Thu, 17 Sep 2026 17:24:08 +0530 [thread overview]
Message-ID: <20260917-root_port-v2-0-0d627d0856d5@oss.qualcomm.com> (raw)
PCIe wake is active low signal as per the PCIe base spec, Several Qualcomm
platform devicetrees incorrectly describe wake-gpios as GPIO_ACTIVE_HIGH.
This series fixes the wake-gpios polarity by using GPIO_ACTIVE_LOW
instead of GPIO_ACTIVE_HIGH.
Tested on Talos Ride & lemans evk platform.
No Fixes tag is added as no functional issue has been observed.

Changes in v2:
- Seperate out the wake patches (Mani)
- there is messup in previous versions instead of sending as v3, I sent
it as v1, to avoid confusion I tried to carry version from the previous version.
- Link to v1: https://patch.msgid.link/20260910-root_port-v1-0-90a252ddbbfa@oss.qualcomm.com
Changes in v3:
- Rebased the code
- keep phy property in between bus-range and address-cells (Konrad)
- Link to v2: https://lore.kernel.org/all/20260611-wake-v2-0-2744251b1181@oss.qualcomm.com/
Changes in v2:
- Move phy, perst & wake properties to the root port node.
- Rebased the code
- Link to v1: https://patch.msgid.link/20260521-wake-v1-0-d822567be258@oss.qualcomm.com
