This driver is for PCH(Platform controller Hub) GPIO of Intel Topcliff
which is an IOH(Input/Output Hub) for x86 embedded processor.
This driver can access PCH GPIO device.
This driver also can be used for OKI SEMICONDUCTOR IOH(Input/
Output Hub), ML7223.
This driver also can be used for LAPIS Semiconductor IOH(Input/
Output Hub), ML7223 and ML7831.
ML7223 IOH is for MP(Media Phone) use.
ML7223 is companion chip for Intel Atom E6xx series.
ML7223 is completely compatible for Intel EG20T PCH.
ML7831 IOH is for general purpose use.
