The series,

Acked-by: Stephen Warren <swarren@...dia.com>

Note that this series will cause some compile breakage in the series I
previously posted to add a pinctrl-tegra driver and convert mach-tegra
to use it. The following patches in that series should still be OK:

pinctrl: add a driver for NVIDIA Tegra
ARM: tegra: Select PINCTRL Kconfig variables

... so you can still go ahead and apply those, but the following will be
broken:

ARM: tegra: Switch to new pinctrl driver
ARM: tegra: Remove pre-pinctrl pinmux driver

also the separately posted:

ARM: tegra: Add pinmux board file for Cardhu

I'll probably hold off reposting those last 3; with any luck they'll be
eclipsed by my implementing full DT binding support in the near future,
given our consensus on that topic following discussion at Linaro Connect.
