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.

each entry consists of 6 integers and represents the mux and config
|
|
setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
|
|
mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
|
|
be found in <arch/arm64/boot/dts/freescale/imx8mp-pinfunc.h>. The last
|
|
integer CONFIG is the pad setting value like pull-up on this pin. Please
|
|
refer to i.MX8M Plus Reference Manual for detailed CONFIG settings.
