61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

2499a04617 ARM: dts: dra7: Change pbias voltage to 3.3V
As per recent TRM[1], PBIAS cell on dra7 devices supports
3.3v and not 3.0v as documented earlier.

Update PBIAS regulator max voltage and the voltage written
in the driver to reflect this.

3c29a56736 regulator: pbias: Handle extended drain IO when changing omap36 PBIAS
The OMAP36 and DM37 TRM state to disable extneded drain IO before
changing the PBIAS.  This patch does this before pmic writes if
the CONFIG_MMC_OMAP36XX_PINS flag is set and the cpu family is
omap36xx

e5f7a261db regulator: pbias: Add additional compatible flags
The driver was developed with references for more than just
dra7, but never included.  At least for omap3, this appears
to be functional.

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>

8ff7763d62 regulator: pbias: Add PBIAS regulator for proper voltage switching on MMC1
In the TI SOCs a PBIAS cell exists to provide a bias voltage to the MMC1
IO cells. Without this bias voltage these I/O cells can not function
properly. The PBIAS cell is controlled by software.
