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.
