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.

that line "just in case" during development and never dropped it.

751641814c video-uclass: Fix logical-not-parentheses warning
With clang-4.0 and later we see:
warning: logical not is only applied to the left hand side of this bitwise
operator [-Wlogical-not-parentheses]
        if ((!gd->flags & GD_FLG_RELOC))
             ^          ~

And while the compiler suggests adding parenthesis around gd->flags, a
reading of the code says that we want to know when GD_FLG_RELOC is not
set and then return.

02325c7bfd treewide: fix up files incorrectly marked executable
Inspired by the following kernel commit:

"commit 90fda63fa1156ec1bcfd7f9ca384cec221f70a21
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Sat Apr 7 13:31:23 2018 -0700

treewide: fix up files incorrectly marked executable

Joe Perches noted that we have a few source files that for some
inexplicable reason (read: I'm too lazy to even go look at the history)
are marked executable:

drivers/gpu/drm/amd/amdgpu/vce_v4_0.c
drivers/net/ethernet/cadence/macb_ptp.c

A simple git command line to show executable C/asm/header files is this:

   git ls-files -s '*.[chsS]' | grep '^100755'

and then you can fix them up with scripting by just feeding that output
into:

  | cut -f2 | xargs chmod -x

and commit it.

Which is exactly what this commit does.

5de0b5a36a rockchip: video: rk_vop: migrate to livetree
This migrates rk_vop (the shared functions used by multiple VOP
mini-drivers) to be compatible with a live tree.

Unfortunately, there's
(i)  a lot of tree traversal needed for a VOP (as each active VOP
     vnode references back to the endpoints in the encoders and vice
     versa) to configure the connection between VOPs and encoders;
(ii) the DTS binding is not too sane and one needs to walk a node's
     parents (the original code just assumed that the device would
     live 3 levels above the property linked through a phandle) until
     a UCLASS_DISPLAY device can be found.

As part of the migration, the code for finding the enclosing display
device has been changed to not assume a specific depth of nesting
(i.e. we walk until we reach the root or find a matching device) and
to use the newly introduced (in the same series) ofnode_get_parent()
function.

a dedicated DPLL for generating a dividable base-clock for this IP-core.

The TRM specifies the maximum input frequency for the LCCD with 200 MHz,
so we must not exceed this value with the PLL frequency (which can lock
much higher).

This patch tries every combination of multipliers and divisors of the
PLL and the IP-core itself for getting as near as possible the the
