336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

63860dbfdf pinctrl: meson-gxbb: add hdmi related pins
The GXBB pinctrl is missing pins related to HDMI, namely hot plug
detection (hpd) and I2C (sda + scl).

This fixes HDMI support for GXBB in u-boot.

478c563b40 pinctrl: meson: add support of drive-strength-microamp
drive-strength-microamp is a new feature needed for G12A SoC.
the default DS setting after boot is usually 500uA and it is not enough for
many functions. We need to be able to set the drive strength to reliably
enable things like MMC, I2C, etc ...

PMX bank to prevent issue in meson_pinconf_set call.

139ebe9eb9 pinctrl: meson: axg: Fix GPIO pin offsets
The pin number (first and last) in the bank definition is missing the
pin base offset shifting. This is causing a miscalculation when
retrieving the register and pin offsets in the GPIO driver causing the
'gpio' command to drive the wrong pins / GPIOs in the second GPIO chip
(the AO bank is driven correctly because the shifting is already 0).

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.

4af0d7e870 dm: Fix up inclusion of common.h
It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.

Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.
