Add a interrupts-names property to allow the possibility to provide a name to any interrupts entries. If the name is available, use it to name the resource, otherwise keep the device full name.

Some properties contain an ordered list of 1 or more datum which are
|
|
normally accessed by index. However, some devices will have multiple
|
|
values which are more naturally accessed by name. Device nodes can
|
|
include a supplemental property for assigning names to each of the list
|
|
items. The names property consists of a list of strings in the same
|
|
order as the data in the resource property.
|
|
|
|
The following supplemental names properties are defined.
|
|
|
|
Resource Property Supplemental Names Property
|
|
----------------- ---------------------------
|
|
reg reg-names
|
|
clocks clock-names
|
|
interrupts interrupt-names
|
|
|
|
Usage:
|
|
|
|
The -names property must be used in conjunction with the normal resource
|
|
property. If not it will be ignored.
|
|
|
|
Examples:
|
|
|
|

|
|
