d69c6ddd01 dt-bindings: Fix JSON pointers
The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

6fdc6e23a7 dt-bindings: Add missing 'unevaluatedProperties'
This doesn't yet do anything in the tools, but make it explicit so we can
check either 'unevaluatedProperties' or 'additionalProperties' is present
in schemas.

'unevaluatedProperties' is appropriate when including another schema (via
'$ref') and all possible properties and/or child nodes are not
explicitly listed in the schema with the '$ref'.

This is in preparation to add a meta-schema to check for missing
'unevaluatedProperties' or 'additionalProperties'. This has been a
constant source of review issues.

086e9074f5 dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another round of 'allOf' removals that came in this cycle.

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.

01c38ecff8 dt-bindings: serial: Add binding for rs485 bus termination GPIO
Commit e8759ad17d ("serial: uapi: Add support for bus termination")
introduced the ability to enable rs485 bus termination from user space.
So far the feature is only used by a single driver, 8250_exar.c, using a
hardcoded GPIO pin specific to Siemens IOT2040 products.

Provide for a more generic solution by allowing specification of an
rs485 bus termination GPIO pin in the device tree.  An upcoming commit
implements support for this pin for any 8250 driver.  The binding is
used in device trees of the "Revolution Pi" PLCs offered by KUNBUS.

[Heiko Stuebner converted the binding to YAML, hence his Signed-off-by.]

fba5618451 dt-bindings: Fix incorrect 'reg' property sizes
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.

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.

e69f5dc623 dt-bindings: serial: Convert 8250 to json-schema
Some fixes were done during the conversion:

Slightly better examples. The original example was for an OMAP serial
port, which is not even described by this binding, but by
omap_serial.txt instead.

Added compatible strings, that were used, byt not documented:
andestech,uart16550, cavium,octeon-3860-uart, fsl,16550-FIFO64,
nvidia,tegra186-uart, nvidia,tegra194-uart, nxp,lpc1850-uart,
opencores,uart16550-rtlsvn105, ralink,mt7620a-uart, ralink,rt3052-uart,
ralink,rt3883-uart and xlnx,xps-uart16550-2.00.b.

Removed "serial" compatible string. It's redundant with the node name
(which, in OFW, serves the same purpose as the compatible string).

7f464532b0 dt-bindings: Add missing 'additionalProperties: false'
Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.
