2019-09-20PCI: tegra: Add support to enable slot regulatorsVidya Sagar
Add support to get regulator information of 3.3V and 12V supplies of a PCIe slot from the respective controller's device-tree node and enable those supplies. This is required in platforms like p2972-0000 where the supplies to x16 slot owned by C5 controller need to be enabled before attempting to enumerate the devices.
