the recent Linux 4.20-rc1, because it includes patches fixing support for
U-boot.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

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).

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.

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.

Every pin can be configured now from the device tree. A dt-bindings
has been added to describe the different property available.
