PCIe wake is active low signal as per the PCIe base spec, Several Qualcomm
platform devicetrees incorrectly describe wake-gpios as GPIO_ACTIVE_HIGH.
The PCIe PHY references and PERST/WAKE GPIO properties are defined on a
per-root-port basis and do not belong to the PCIe controller (RC)
node. Keeping these properties at the controller level makes the
description less accurate and prevents clean per-port customization.
This series moves the PHY references (phys, phy-names) from the PCIe
controller node to the corresponding root port nodes (pcie@0), namely
pcie0_port0, pcie1_port0, and pcie2_port0. Labels are added to these
port nodes to enable board-level overrides where required.
Additionally, the PERST and WAKE GPIO properties are relocated from
controller-level board overrides to their respective root port nodes
in the board DTS files. As part of this change, 'perst-gpios' is renamed
to 'reset-gpios' to align with the binding used in the PCIe root port
context.
This restructuring improves DT correctness by properly associating
resources with their respective hardware blocks and aligns with the
expectations defined in the PCIe binding.
Tested on Talos Ride & lemans evk platform.
No Fixes tag is added as no functional issue has been observed.
