POWER ISA v3 defines a new idle processor core mechanism. In summary,
a) new instruction named stop is added. This instruction replaces
instructions like nap, sleep, rvwinkle.
b) new per thread SPR named Processor Stop Status and Control Register
(PSSCR) is added which controls the behavior of stop instruction.
This patch series adds support for the new idle states and also has
some minor cleanups.
Changes in V3:
- Rebased on master
- Added documentation for device tree bindings
- minor whitespace cleanup
Changes in V2:
- Patches are based on top of "[PATCH v2 0/7] Add POWER9 support"
