2c0f782e0f gpio: sandbox: cleanup binding support
Cleanup binding support, use the generic binding by default
(test u-class gpio_xlate_offs_flags function) and add
specific binding for added value.

1bb257a9b3 dt-bindings: gpio: document the new pull-up/pull-down flags
This commit extends the flags that can be used in GPIO specifiers to
indicate if a pull-up resistor or pull-down resistor should be
enabled.

It is the backport of linux commit ede033e1e863c ('dt-bindings:
gpio: document the new pull-up/pull-down flags')
from Thomas Petazzoni <thomas.petazzoni@bootlin.com>
and integrated in v5.1-rc1

dd5f2351e9 arm64: dts: meson: sync dt and bindings from v5.6-rc2
Sync the device tree and dt-bindings from Linux v5.6-rc2
11a48a5a18c6 ("Linux 5.6-rc2")

The only exception to this is the mmc pinctrl pin bias of gxl SoC family.
This is a fix which found its way to u-boot but not Linux yet.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

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.
