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/
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.
