In linux kernel since version 2.6.37 (release Date: 2011-01-04)
This driver is for PCH (Platform Controller Hub) GPIO of Intel Topcliff,
which is an IOH (Input/Output Hub) for x86 embedded processor.
This driver can access PCH GPIO device.
This driver also can be used for LAPIS Semiconductor IOH (Input/
Output Hub), ML7223 and ML7831.
ML7223 IOH is for MP (Media Phone) use.
ML7831 IOH is for general purpose use.
ML7223/ML7831 is companion chip for Intel Atom E6xx series.
ML7223/ML7831 is completely compatible for Intel EG20T PCH.
