dt-bindings: arm: Fixup the DT bindings for hierarchical PSCI states

2020-03-06T18:12:21+00:00

The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the
power-domain DT binding.

Additionally, update the example to conform to the new pattern, but also to
the adjusted domain-idle-state DT binding.

dt-bindings: power: Convert domain-idle-states bindings to json-schema

2020-03-04T14:49:36+00:00

While converting to the json-schema, let's also take the opportunity to
further specify/clarify some more details about the DT binding.

For example, let's define the label where to put the states nodes, set a
pattern for nodename of the state nodes and finally add an example.

dt-bindings: arm: Correct links to idle states definitions

2020-03-04T14:46:53+00:00

The arm,idle-state DT bindings recently got converted to the json-schema,
but some links are still pointing to the old, non-existing, txt file. Let's
update the links to fix this.

dt-bindings: Fix dtc warnings in examples

2020-02-28T20:15:52+00:00

Fix all the warnings in the DT binding schema examples when built with
'W=1'. This is in preparation to make that the default for examples.

dt-bindings: Fix paths in schema $id fields

2020-02-05T09:14:57+00:00

The $id path checks were inadequately checking the path part of the $id
value. With the check fixed, there's a number of errors that need to be
fixed. Most of the errors are including 'bindings/' in the path which
should not be as that is considered the root.
