ac2babe70a dt-bindings: iio: temperature: ltc2983: Make 'adi,custom-thermocouple' signed
The 'adi,custom-thermocouple' property is signed based on the example
and driver, so it's type should be int64-matrix rather than
uint64-matrix.

543c8f2f3c dt-bindings: iio: temperature: ltc2983: Fix child node unevaluated properties
The child node schemas are missing 'unevaluatedProperties' constraints,
so any unknown properties are allowed. The current structure with
multiple patternProperties schemas doesn't work for
unevaluatedProperties as each sub-schema is evaluated independently. To
fix this, move the sub-schema for all child nodes to a $defs entry and
reference it from each named child node.

a0666f7f0f dt-bindings: iio: temperature: ltc2983: drop $ref for -nanoamp properties
Currently there are -nanoamp properties both with and without a $ref.
dt-schema has been modified to handle it as a standard unit, but the
change has been reverted since there were still occurrences of
-nanoamp properties with a $ref.
Remove this since it's the only occurrence left.

Add support for the following parts:

 * LTC2986
 * LTM2985

The LTC2984 is a variant of the LTC2983 with EEPROM.
The LTC2986 is a variant of the LTC2983 with only 10 channels,
EEPROM and support for active analog temperature sensors.
The LTM2985 is software-compatible with the LTC2986.

The '/bits/ 64' notation applies the next <> list of values. Another <> list
is encoded as 32-bits by default. IOW, each <> list needs to be preceeded
with '/bits/ 64'.

While the dts format allows this, as a rule we don't mix sizes for DT
properties since all size information is lost in the dtb file.

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.

b02a728ff3 dt-bindings: iio: Fix adi, ltc2983 uint64-matrix schema constraints
'minItems' and 'maxItems' apply at the same level as 'items' schemas as
the keywords apply to arrays. What's currently defined is a 3
dimensional matrix with the outer size being undefined. To fix this,
minItems/maxItems needs to be moved up a level.

With this fixed, the example fails validation. For matrix types, the dts
syntax must use brackets (<>) matching the schema definition. In this
case, the inner array size is 2 elements, so let's add the correct
bracketing.

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.
