[PATCH v2 22/37] arm64: dts: qcom: qcs8550: Move PCIe GPIOs to root port node
From: Krishna Chaitanya Chundru
Date: Thu Jun 11 2026 - 01:08:02 EST
The perst/wake GPIO properties are per root port and belong in the
root port node, not in the RC controller node. Move perst-gpios/
wake-gpios from the &pcie0/&pcie1 controller overrides to the
respective &pcieport0/&pcie1_port0 nodes, renaming perst-gpios to
reset-gpios to match the binding used in the root port context.
