This is needed by drivers which want to use dev_pm_opp_set_rate() for changing rates of a multiple clocks and don't need to touch regulator. One example is NVIDIA Tegra30/114 SoCs which have two sibling 3D hardware units which should be use to the same clock rate, meanwhile voltage scaling is done using a power domain. In this case OPP table doesn't have a regulator, causing a NULL dereference in _set_opp_custom().

Core power domain covers vast majority of hardware blocks within a Tegra SoC. The voltage of a power domain should be set to a value which satisfies all devices within a power domain. Add driver for the core power domain in order to manage the voltage state of the domain. This allows us to support a system-wide DVFS on Tegra.

In order to support voltage scaling of the core power rail, we need to hook up some clocks (which can't operate properly on a lower voltages above certain clock rates) to the core power domain in order to ensure that a proper core voltage is maintained. The clocks are registered very early during kernel boot when the driver core isn't available yet. Hence clk-device can't be created very early and we need to split the registration of the clocks in two phases: 1. Register all essential clocks which don't use RPM and may be needed during early boot. 2. Register all clocks that use RPM (and not needed early) at a later boot time, once driver core is available. That's the reason why this patch reshuffles registration of a few clocks.
