Subject: [PATCH v2 08/15] arm64: dts: qcom: sm8250: Move PCIe phy and GPIOs to root port node
Date: Thu, 17 Sep 2026 17:55:22 +0530 [thread overview]
Message-ID: <20260917-root_port_v2-v2-8-6272b7caae9a@oss.qualcomm.com> (raw)
In-Reply-To: <20260917-root_port_v2-v2-0-6272b7caae9a@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, phy-names, perst-gpios, and wake-gpios
from the controller to the existing pcieport0 and newly labeled
pcie1_port0 and pcie2_port0, allowing board-level overrides. Rename
perst-gpios to reset-gpios to match the binding used in the root
port context.
