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.

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.

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
