This new API is primarily needed for syncing state of SoC devices that are left ON after bootloader or permanently enabled. All these devices belong to a shared CORE voltage domain, and thus, we needed to bring all the devices into expected state before the voltage scaling could be performed. All drivers of DVFS-critical devices shall sync theirs the state before Tegra's voltage regulator coupler will be allowed to perform a system-wide voltage scaling.

The new sync state API resolves this problem for us. All drivers of the devices that are known to be ON at a boot time now should sync theirs state. Once everything is synced, the voltage of the CORE domain could be scaled without any limitations. Make Tegra20/30 regulator couplers to use the new sync state API.

This new option is needed for the NVIDIA Tegra voltage couplers in order to properly calculate a lowest possible voltage for the CORE regulator. The requirements of a disabled consumer regulators should not be accounted by the Tegra voltage balancers because disabled state means that hardware is inactive. In particular disabled state shouldn't be accounted for the consumers which belong to the CORE voltage domain, meanwhile CPU domain should continue to account the disabled state.
