	  This driver supports the MSM GFX (Graphics) LDO regulator. The

	  GFU core is either powered by an internal MSM LDO or by BHS.

	  Typically the lower voltage corners are powered by LDO and

	  the higher ones by BHS. This driver allows for configuration of

	  the rail between the LDO/BHS as well as the LDO voltage.
