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.

This interrupt controller is found in the Loongson-3 family of chips as the primary
|
|
package interrupt controller which can route local I/O interrupt to interrupt lines
|

of cores.

This property points how the children interrupts will be mapped into CPU
|
|
interrupt lines. Each cell refers to a parent interrupt line from 0 to 3
|
|
and each bit in the cell refers to a children interrupt fron 0 to 31.
|
|
If a CPU interrupt line didn't connected with liointc, then keep it's
|
|
cell with zero.
