PCI: tegra: Add loadable kernel module support Implement remove callback function for Tegra PCIe driver to add loadable kernel module support. Per PCIe r3.0, sec 5.3.3.2.1, PCIe root port should broadcast PME_Turn_Off message before PCIe link goes to L2. PME_Turn_Off broadcast mechanism is implemented in AFI module. Each Tegra PCIe root port has its own PME_Turn_Off and PME_TO_Ack bitmap in AFI_PME register, program this register to broadcast PME_Turn_Off message. Once PME_TO_Ack is recieved driver will turn OFF PCIe clock, power gate PCIe partition and turn OFF regulators.
