074a1fdd27 gpio: add Tegra186 GPIO driver
Tegra186's GPIO controller register layout is significantly different from
previous chips, so add a new driver for it. In fact, there are two
different GPIO controllers in Tegra186 that share a similar register
layout, but very different port mapping. This driver covers both.

The DT binding is already present in the Linux kernel (in linux-next via
the Tegra tree so far).

e6bf0ca0e2 ARM: tegra: fix naming in GPIO DT binding header
According to the Tegra TRM, GPIOs are aggregated into /ports/ of 8 GPIOs,
not into /banks/. Fix <dt-bindings/gpio/tegra-gpio.h> to correctly reflect
this naming convention. While this seems like silly churn, it will become
slightly more important once we introduce the GPIO binding for upcoming
Tegra chips. This mirrors an identical commit in the Linux kernel.

b24f5c4f27 x86: broadwell: Add a pinctrl driver
GPIO pins need to be set up on start-up. Add a driver to provide this,
configured from the device tree.

The binding is slightly different from the existing ICH6 binding, since that
is quite verbose. The new binding should be just as extensible.

5318f18d2c x86: gpio: add pinctrl support from the device tree
Every pin can be configured now from the device tree. A dt-bindings
has been added to describe the different property available.
