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 Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
|
|
with an active array size of 3280H x 2464V. It is programmable through
|
|
I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
|
|
Image data is sent through MIPI CSI-2, which is configured as either 2 or
|
|
4 data lanes.

|
The sensor supports either two-lane, or four-lane operation.
|
|
If this property is omitted four-lane operation is assumed.
|
|
For two-lane operation the property must be set to <1 2>.
