7 title: Power State Coordination Interface (PSCI)
13 Firmware implementing the PSCI functions described in ARM document number
21 Functions are invoked by trapping to the privilege level of the PSCI
31 [2] Power State Coordination Interface (PSCI) specification
36 const: psci
41 For implementations complying to PSCI versions prior to 0.2.
42 const: arm,psci
45 For implementations complying to PSCI 0.2.
47 PSCI 0.2 support, but are permitted to be present for compatibility
