Merge tag 'tegra-for-4.7-phy' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers
Merge "phy: tegra: Changes for v4.7-rc1" from Thierry Reding:
This set of patches adds support for the Tegra XUSB pad controller. The
controller provides a set of pads (lanes) that are used for I/O by other
IP blocks within Tegra SoCs (PCIe, SATA and XUSB).
* tag 'tegra-for-4.7-phy' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
phy: tegra: Add Tegra210 support
phy: Add Tegra XUSB pad controller support
dt-bindings: phy: tegra-xusb-padctl: Add Tegra210 support
dt-bindings: phy: Add NVIDIA Tegra XUSB pad controller binding
phy: core: Allow children node to be overridden
clk: tegra: Add interface to enable hardware control of SATA/XUSB PLLs
