phy: Add Tegra XUSB pad controller support Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs. This hardware block used to be exposed as a pin controller, but it turns out that this isn't a good fit. The new driver and DT binding much more accurately describe the hardware and are more flexible in supporting new SoC generations.

phy: tegra: Select USB_COMMON for usb_get_maximum_speed() The usb_get_maximum_speed() function is part of the usb-common module, so enable it by selecting the corresponding Kconfig symbol. While at it, also make sure to depend on USB_SUPPORT because USB_PHY requires that. This can lead to Kconfig conflicts if USB_SUPPORT is not enabled while attempting to enable PHY_TEGRA_XUSB.

Choose this option if you have an NVIDIA Tegra SoC.
To compile this driver as a module, choose M here: the module will
be called phy-tegra-xusb.
phy: tegra: Add PCIe PIPE2UPHY support Synopsys DesignWare core based PCIe controllers in Tegra 194 SoC interface with Universal PHY (UPHY) module through a PIPE2UPHY (P2U) module. For each PCIe lane of a controller, there is a P2U unit instantiated at hardware level. This driver provides support for the programming required for each P2U that is going to be used for a PCIe controller.
