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.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

b616835ddf power: regulator: max77686: get_enable should return integer
get_enable should be able to return error values. Hence change
the return type to integer.

aae78fa774 drivers/power/regulator/max77686.c: Fix comparisons of unsigned expressions
Inside of
max77686_buck_volt2hex/max77686_buck_hex2volt/max77686_ldo_volt2hex we
check that the value we calculate is >= 0 however we declare 'hex' as
unsigned int making these always true.  Mark these as 'int' instead.  We
also move hex_max to int as they are constants that are 0x3f/0xff.
Given that the above functions are marked as returning an int, make the
variables we assign their return value to also be int to be able to
catch the error condition now.  Reported by clang-3.8.

6d6aececfe power: regulator: max77686: Don't use switch() on bools
With gcc-5.3 we get a warning for using switch() on a bool type.
Rewrite these sections as if/else and update the one section that was
using 1/0 instead of true/false.

1757df4693 dm: regulator: add max77686 regulator driver
This commit adds support to MAX77686 regulator driver,
based on a driver model regulator's API. It implements
almost all regulator operations, beside those for setting
and geting the Current value.
For proper bind and operation it requires the MAX77686 PMIC driver.
