Subject: [PATCH 41/90] arm: psci: Add definitions for PSCI v1.1
|
|
|
|
Add the new option, function IDs, and prototypes for PSCI v1.1
|
|
implementations. In the process, fix some issues with the existing
|
|
definitions:
|
|
- Fix the incorrectly-named ARM_PSCI_0_2_FN64_SYSTEM_RESET2.
|
|
- Replace the deprecated "affinity_level" naming with "power_level".
|
