	  This driver is for PCH(Platform controller Hub) I2C of EG20T which

	  is an IOH(Input/Output Hub) for x86 embedded processor.

	  This driver can access PCH I2C bus device.



	  This driver also supports the ML7213, a companion chip for the

	  Atom E6xx series and compatible with the Intel EG20T PCH.

	  This driver also can be used for OKI SEMICONDUCTOR IOH(Input/

	  Output Hub), ML7213 and ML7223.

	  ML7213 IOH is for IVI(In-Vehicle Infotainment) use and ML7223 IOH is

	  for MP(Media Phone) use.
