This patch set is to enable sp804 timer on Hi3660 for Hikey960 platform. On Hi3660, the sp804 timer co-exists with CPUs' architecture timer; but sp804 timer is located in SoC level but CPU's architecture timer is in CPU power domain. sp804 timer is used as broadcast timer when CPU enters idle states and the CPU (includes architecture timer) power domain is powered off. So sp804 timer enabling is prerequisite before we enable CPUIdle on Hi3660. This patch set is to enable sp804 timer, the first patch is to adjust crgctrl clock regiseration so ensure clock is avaiable for timer. The second patch is to add description for timer in dts. Have rebased this patch set on Guodong's dts patch set [1] and verified this patch set on Hikey960.
