The whole thing will probably need to go into one branch.  Patch 4/9
("pinctrl: tegra-xusb: Add USB PHY support") has compile-time
dependencies on patch 2/9 ("mailbox: Add NVIDIA Tegra XUSB mailbox
driver") and patch 6/9 ("usb: xhci: Add NVIDIA Tegra xHCI
host-controller driver") has compile-time dependencies on both patches
2/9 and 4/9.
