Tegra XHCI controler can be placed in ELPG (Engine Level PowerGated)
state for power saving when all of the connected USB devices are in
suspended state. This patch series includes clk, phy and pmc changes
that are required for properly place controller in ELPG and bring
controller out of ELPG.

JC Kuo (15):
  clk: tegra: Add PLLE HW power sequencer control
  clk: tegra: Don't enable PLLE HW sequencer at init
  phy: tegra: xusb: Move usb3 port init for Tegra210
