e3812b5b08 led: pwm: Use NOP uclass driver for top-level node
The top level DT node of pwm-leds is not a LED itself, bind NOP uclass
driver to it, and bind different LED uclass driver to its subnodes which
represent the actual LEDs. This change removes the top-level node from
the 'led list' command output and is based on the commit 0107469780
("led: gpio: Use NOP uclass driver for top-level node").

b340199f82 spl: Ensure all SPL symbols in Kconfig have some SPL dependency
Tighten up symbol dependencies in a number of places.  Ensure that a SPL
specific option has at least a direct dependency on SPL.  In places
where it's clear that we depend on something more specific, use that
dependency instead.  This means in a very small number of places we can
drop redundant dependencies.

877de2a369 drivers: led: bcm6858: Set a default brightness when probing LEDs
When probing the LEDs, a default brightness is set based on settings
from the U-Boot device tree, i.e. the 'default-brightness' property
of the LED nodes. If that property is not present, the default
maximum brightness is set.
This should make sure the LED controller's registers affecting the
brightness are correctly initialized and should give a consistent
behaviour.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
