[PATCH 0/2] PCI: qcom: Add support for firmware-managed PCIe controller recovery

[Mrinmay Sarkar]

This series adds recovery support for firmware-managed Qualcomm PCIe
controllers.

For these controllers, firmware manages resources such as PHY, clocks,
resets and LTSSM through the power-domain framework.

Patch 1 adds Root Port reset support by power-cycling the controller
through Runtime PM, allowing firmware to reset and reinitialize the
hardware.

Patch 2 restores the DesignWare MSI configuration after resume, as MSI
register contents are lost across the controller power cycle.
