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 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.
- ML7213/ML7223 is companion chip for Intel Atom E6xx series.
- ML7213/ML7223 is completely compatible for Intel EG20T PCH.
+ This driver also can be used for LAPIS Semiconductor IOH(Input/
+ Output Hub), ML7213, ML7223 and ML7831.
+ ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is
+ for MP(Media Phone) use and ML7831 IOH is for general purpose use.
