i2c-eg20t: Support new device ML7223 IOH
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. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

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.
+ ML7213/ML7223 is companion chip for Intel Atom E6xx series.
+ ML7213/ML7223 is completely compatible for Intel EG20T PCH.
