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. Signed-off-by: Rob Herring <robh@kernel.org>

The driver can utilize information from a simple-battery linked via a
|
|
phandle in monitored-battery. If specified the driver uses the
|
|
charge-full-design-microamp-hours property of the battery.

This property specifies characteristics of the battery used. The format
|
|
of this binary blob is kept secret by CellWise. The only way to obtain
|
|
it is to mail two batteries to a test facility of CellWise and receive
|
|
back a test report with the binary blob.
