f2b0fe4b12 dt-bindings: serial: pl011: Delete an incorrect compatible string
The compatible strings "zte,zx296702-uart" and "arm,primecell" are a
combination, but commit 89d4f98ae9 ("ARM: remove zte zx platform")
removes only the former. It is incorrect to match driver pl011 based only
on the remaining "arm,primecell". Delete it.

8f082dcf2c dt-bindings: serial: Change to reference the kernel-defined serial.yaml
The /schemas/serial.yaml from dt-schema only has the property $nodename,
whereas the kernel-defined /schemas/serial/serial.yaml contains more
useful properties, support for more complex application scenarios.

For example:
1) The property "current-speed" in fsl-lx2160a.dtsi
2) The subnode "bluetooth" in hi3660-hikey960.dts

584ce3c9b4 SoC platform removal
There are a lot of platforms that have not seen any interesting code
 changes in the past five years or more.
 
 I made a list and asked around which ones are no longer in use [1], and
 received confirmation about six ARM platforms and the TI C6x architecture
 that have all reached the end of their life upstream, with no known
 users remaining:
 
  - efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
  - picoxcell -- added in 2011, abandoned after 2012 acquisition
  - prima2 -- added in 20111, no notable changes since 2015
  - tango -- added in 2015, sporadic changes until 2017, but abandoned
  - u300 -- added in 2009, no notable changes since 2013
  - zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
  - arch/c6x -- added in 2011, but work stalled soon after that
 
 A number of other platforms on the original list turned out to still
 have users. In some cases there are out-of-tree patches and users
 that plan to contribute them in the future, in other cases the code
 is complete and works reliably.

32ada6b098 dt-bindings: Cleanup standard unit properties
Properties with standard unit suffixes already have a type and don't need
type definitions. They also default to a single entry, so 'maxItems: 1'
can be dropped.

adi,ad5758 is an oddball which defined an enum of arrays. While a valid
schema, it is simpler as a whole to only define scalar constraints.

89d4f98ae9 ARM: remove zte zx platform
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.

However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.

Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.

Thanks to Jun and Shawn for maintaining this platform over the past
five years.

3d21a46093 dt-bindings: Remove cases of 'allOf' containing a '$ref'
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Convert the arm,pl011 binding to DT schema using json-schema.

The zte,zx296702-uart binding appears to be broken as the dts files are
missing 'arm,primecell'. That's included in the schema here to throw a
warning.
