           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.
+          ML7223 is completely compatible for Intel EG20T PCH.
