The correct syntax for JSON pointers begins with a '/' after the '#'. Without a '/', the string should be interpreted as a subschema identifier. The jsonschema module currently doesn't handle subschema identifiers and incorrectly allows JSON pointers to begin without a '/'. Let's fix this before it becomes a problem when jsonschema module is fixed.

The MIPS GIC routes external interrupts to individual VPEs and IRQ pins.
|
|
It also supports local (per-processor) interrupts and software-generated
|
|
interrupts which can be used as IPIs. The GIC also includes a free-running
|
|
global timer, per-CPU count/compare timers, and a watchdog.

|
The 1st cell is the type of interrupt: local or shared defined in the
|
|
file 'dt-bindings/interrupt-controller/mips-gic.h'. The 2nd cell is the
|
|
GIC interrupt number. The 3d cell encodes the interrupt flags setting up
|
|
the IRQ trigger modes, which are defined in the file
|
|
'dt-bindings/interrupt-controller/irq.h'.

Specifies the range of GIC interrupts that are reserved for IPIs.

It accepts two values: the 1st is the starting interrupt and the 2nd is

the size of the reserved range. If not specified, the driver will
|
|
allocate the last (2 * number of VPEs in the system).
