Required Properties:
|
||||
--------------------
|
||||
- compatible: should be "ti,sci-pm-domain"
|
||||
- #power-domain-cells: Must be 1 so that an id can be provided in each
|
||||
device node.
|
||||
- #power-domain-cells: Can be one of the following:
|
||||
1: Containing the device id of each node
|
||||
2: First entry should be device id
|
||||
Second entry should be one of the floowing:
|
||||
TI_SCI_PD_EXCLUSIVE: To allow device to be
|
||||
exclusively controlled by
|
||||
the requesting hosts.
|
||||
TI_SCI_PD_SHARED: To allow device to be shared
|
||||
by multiple hosts.
