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.

Devices on SOCs often have mechanisms for placing devices into low-power
|
|
states that are decoupled from the devices' own register blocks. Sometimes,
|
|
this information is more complicated than a cell-index property can
|
|
reasonably describe. Thus, each device controlled in such a manner
|
|
may contain a "sleep" property which describes these connections.
|
|
|
|
The sleep property consists of one or more sleep resources, each of
|
|
which consists of a phandle to a sleep controller, followed by a
|
|
controller-specific sleep specifier of zero or more cells.
|
|
|
|
The semantics of what type of low power modes are possible are defined
|
|
by the sleep controller. Some examples of the types of low power modes
|
|
that may be supported are:
|
|
|
|
- Dynamic: The device may be disabled or enabled at any time.
|
|
- System Suspend: The device may request to be disabled or remain
|
|
awake during system suspend, but will not be disabled until then.
|
|
- Permanent: The device is disabled permanently (until the next hard
|
|
reset).
|
|
|
|
Some devices may share a clock domain with each other, such that they should
|
|
only be suspended when none of the devices are in use. Where reasonable,
|
|
such nodes should be placed on a virtual bus, where the bus has the sleep
|
|
property. If the clock domain is shared among devices that cannot be
|
|
reasonably grouped in this manner, then create a virtual sleep controller
|
|
(similar to an interrupt nexus, except that defining a standardized
|
|
sleep-map should wait until its necessity is demonstrated).
