16   Some TI SoCs contain a system controller (like the Power Management Micro
17   Controller (PMMC) on Keystone 66AK2G SoC) that are responsible for controlling
19   between the host processor running an OS and the system controller happens
20   through a protocol called TI System Control Interface (TI-SCI protocol).
22   This PM domain node represents the global PM domain managed by the TI-SCI
23   controller. Since this relies on the TI SCI protocol to communicate with
24   the TI-SCI controller, it must be a child of the TI-SCI controller node.
28     const: ti,sci-pm-domain
30   "#power-domain-cells":
33       The two cells represent values that the TI-SCI controller defines.
37       The second cell, if cell-value is 2, should be one of the following
38       TI_SCI_PD_EXCLUSIVE - Allows the device to be exclusively controlled
40       TI_SCI_PD_SHARED - Allows the device to be shared by multiple hosts.
41       Please refer to dt-bindings/soc/ti,sci_pm_domain.h for the definitions.
