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.

Convert the exynos GPIO driver to driver model. This implements the generic
GPIO interface but not the extra Exynos-specific functions.

The wrong header is being included, thus requiring the code to re-declare
the generic GPIO interface in each GPIO header.
Fix this.

This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
To have consistent 0..n-1 GPIO numbering the banks are divided
into different parts where ever they have holes in them.
* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
These changes were done to enable cmd_gpio for EXYNOS and
cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
getting a error during compilation.
* Adds support for name to gpio conversion in s5p_gpio to enable
gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
to decode the input gpio name to gpio number.
Example: SMDK5420 # gpio set gpa00

Old s5p gpio coding method was not clean and was not working properly
for all parts and banks. New method is clean and easy to extend.
Gpio coding mask:
0x000000ff - pin number
0x00ffff00 - bank offset
0xff000000 - part number

Now proper GPIO parts numbering is handled at Samsung devices.
This fix is necessary for code using GPIO located at other banks
than first.

This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.
This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

Typically we declare the name of gpio structure to "gpio",
so it was duplicated around the name. (e.g: gpio->gpio_a)
This patch modified the naming that is removing "gpio_".

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
