Subject: [PATCH v2 36/37] arm64: dts: qcom: kodiak: Move PCIe phy and GPIOs to root port node
Date: Thu, 11 Jun 2026 10:29:12 +0530	[thread overview]
Message-ID: <20260611-wake-v2-36-2744251b1181@oss.qualcomm.com> (raw)
In-Reply-To: <20260611-wake-v2-0-2744251b1181@oss.qualcomm.com>

The PCIe phy reference and the perst/wake GPIO properties are
per-root port and belong in the root port node (pcie@0), not in the
RC controller node. Move phys from the controller to pcie0_port and
pcie1_port0, and move perst-gpios/wake-gpios from the &pcie0/&pcie1
controller overrides to the respective &pcie0_port/&pcie1_port0 nodes
in the board files, renaming perst-gpios to reset-gpios to match the
binding used in the root port context.
