Rob Herring 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.

title: TMP513/512 system monitor sensor
maintainers:

description: |
The TMP512 (dual-channel) and TMP513 (triple-channel) are system monitors
that include remote sensors, a local temperature sensor, and a high-side
current shunt monitor. These system monitors have the capability of measuring
remote temperatures, on-chip temperatures, and system voltage/power/current
consumption.

properties:
compatible:
enum:
- ti,tmp512
- ti,tmp513
reg:
maxItems: 1
shunt-resistor-micro-ohms:
description: |
If 0, the calibration process will be skiped and the current and power
measurement engine will not work. Temperature and voltage measurement
will continue to work. The shunt value also need to respect:
rshunt <= pga-gain * 40 * 1000 * 1000.
If not, it's not possible to compute a valid calibration value.
default: 1000
ti,pga-gain:
description: |
The gain value for the PGA function. This is 8, 4, 2 or 1.
The PGA gain affect the shunt voltage range.
The range will be equal to: pga-gain * 40mV
$ref: /schemas/types.yaml#/definitions/uint32
enum: [1, 2, 4, 8]
default: 8
ti,bus-range-microvolt:
description: |
This is the operating range of the bus voltage in microvolt
$ref: /schemas/types.yaml#/definitions/uint32
enum: [16000000, 32000000]
default: 32000000
ti,nfactor:
description: |
Array of three(TMP513) or two(TMP512) n-Factor value for each remote
temperature channel.
See datasheet Table 11 for n-Factor range list and value interpretation.
