This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support.

Enable support for the power domain driver class. Many SoCs allow
|
|
power to be applied to or removed from portions of the SoC (power
|
|
domains). This may be used to save power. This API provides the
|
|
means to control such power management hardware.
