-          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's IOH,
+          ML7213/ML7223/ML7831.
+          ML7213 which is for IVI(In-Vehicle Infotainment) use.
+          ML7223 IOH is for MP(Media Phone) use.
+          ML7831 IOH is for general purpose use.
+          ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series.

           To compile this driver as a module, choose M here: the module will
           be called pch_phub.
