From: Leo Yan <leo.yan@linaro.org>
On Hi3660 there have two clusters, one is CA53 cluster and another is
CA73 cluster. This two clusters have different idle states separately.
With Daniel Lezcano's patch (ARM: cpuidle: Support asymmetric idle
definition), now ARM idle driver can support different clusters with
different idle states.
Base on this, this patch is to bind two clusters idle states on Hi3660.
Except the "WFI" states are enabled by default for all CPUs, this patch
also binds below extra idle states:
- CA53 CPUs have two more states:
CPU_SLEEP: CPU power off state
CLUSTER_SLEEP_0: Cluster power off state
- CA73 CPUs have three more states:
CPU_NAP: CPU retention state
CPU_SLEEP: CPU power off state
CLUSTER_SLEEP_1: Cluster power off state
