Browse Source 
Support new device OKI SEMICONDUCTOR ML7223 IOH(Input/Output Hub).
The ML7223 IOH is for MP(Media Phone) use.
The ML7223 is companion chip for Intel Atom E6xx series.
The ML7223 is completely compatible for Intel EG20T PCH.

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.
ML7223 IOH is for MP(Media Phone) use.
ML7223 is companion chip for Intel Atom E6xx series.
