[PATCH 0/4] arm64: Hi6220: enable CPU idle states

[leo.yan@linaro.org (Leo Yan)]

This patch series is to enable CPU idle states for Hi6220.

Hi6220 uses PSCIv0.2 compliance interface, so directly use ARM's generic
CPUIdle driver. Patch 1 is to reserve memory regions so make sure MCU can
work well to handle power controlling; Patch 2/3 enable sp804 timer as
broadcast timer during idle states; Patch 4 registers CPU power down state
and cluster power down state.
