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);
}}}
