which is an IOH(Input/Output Hub) for x86 embedded processor.
Enabling PCH_DMA, this PCH UART works as DMA mode.
- This driver also can be used for OKI SEMICONDUCTOR IOH(Input/

- 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.
