Comment(by dilinger):

 But we should be following himax's instructions of:

 {{{
 We suggest when turn on +3.3 V , send eight SMB clock first  and SMDAT
 keep high . DCON state machine
 will reset to initial state. and we can  normal control SMBUS.
 }}}


 {{{
 22:23 < Mitch_Bradley> #define SMBPINS 0xc000\n#define SMBCLR
 (SMBPINS<<16)\noutl(SMBCLR,0x1010);outl(SMBCLR,0x1014);outl(SMBCLR,0x1034);outl(SMBPINS,0x1000);outl(SMBPINS,0x1004);
 }}}
