Merge branch 'pm-cpuidle'
* pm-cpuidle:
drivers: cpuidle: initialize big.LITTLE driver through DT
drivers: cpuidle: CPU idle ARM64 driver
drivers: cpuidle: implement DT based idle states infrastructure
cpuidle: big.LITTLE: add Exynos5800 compatible string
cpuidle: Replace strnicmp with strncasecmp
arm64: add PSCI CPU_SUSPEND based cpu_suspend support
arm64: kernel: introduce cpu_init_idle CPU operation
arm64: kernel: refactor the CPU suspend API for retention states
Documentation: arm: define DT idle states bindings
