8ee54672df gpio: atmel_pio4: give a full configuration when muxing pins
When a pin is muxed to a peripheral or as a GPIO, the only
configuration that can be set is the pullup. It is too restrictive
so this patch allows to give a full configuration.

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.

381996c5ed sunxi: gpio: add missing compatible strings
The sunxi GPIO driver is missing some compatible strings for recent
SoCs. While most of the sunxi GPIO code seems to not rely on this (and
so works anyway), the sunxi_name_to_gpio() function does and fails at
the moment (for instance when resolving the MMC CD pin name).
Add the compatible strings for the A64 and V3s, which were missing
from the list. This now covers all pinctrl nodes in our own DTs.

1e5f89881a gpio: pca953x_gpio: Support label setting from DT
The PCA953x driver uses "gpio@%x_" as the GPIO bank name, where "%x" is
instantiated with the I2C address of the chip. While this works, it
becomes very confusing if a board has multiple PCAs with the same
address on different I2C busses, and it also becomes an issue when a
GPIO's value is to be set via the 'gpio' command, because this command
only ever sets the value of the first device it encounters, leaving the
other devices inaccessible to the command.

As to not break boards that rely on this naming scheme, we introduce a
new device tree string property "label" for the driver. If it exists, it
is used to build a bank name of the form "%s@%x_" (where %x is still
instantiated with the I2C address). If it does not exist, the legacy
labeling scheme is used.

995b60b593 sandbox: Rename 'num-gpios' property to avoid dtc warning
At present dtc produces these warnings when compiling sandbox:

arch/sandbox/dts/test.dtb: Warning (gpios_property):
	Could not get phandle node for /base-gpios:num-gpios(cell 0)
arch/sandbox/dts/test.dtb: Warning (gpios_property):
	Missing property '#gpio-cells' in node /reset-ctl or bad phandle
	(referred from /extra-gpios:num-gpios[0])

Both are due to it assuming that the 'num-gpios' property holds a phandle
pointing to a GPIO node.

To avoid these warnings, rename the sandbox property so that it does not
include the string 'gpios'.

caf2233b28 bcm283x: Add pinctrl driver
The bcm283x family of SoCs have a GPIO controller that also acts as
pinctrl controller.

This patch introduces a new pinctrl driver that can actually properly mux
devices into their device tree defined pin states and is now the primary
owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.

That way whenever a device asks for pinctrl support, it gets it
automatically from the pinctrl driver and GPIO support is still available
in the normal command line phase.

c5fb1c2524 gpio: uniphier: rework single device node model
First, I implemented this driver as per-bank model, but it was
a design mistake.

  - There are 31 banks in the maximum case.  It is painful to add
    so many nodes to DT.

  - The IRQ control registers are shared between banks.  Per-bank
    design is a problem for Linux.  The counterpart for Linux turned
    around to the single node model.
