 ps: according the the schem the vibra should be controlled by the auxdac
 of iota. i poked it and some enable bit few minutes, but couldnt get it
 doing anything. 
Have you turned the Auxiliary DAC on ? It has its own power control
bit and bit 5 (ADACS) in TOGBR1 hat to be set to turn the Auxiliary DAC
on. I just did a quick test with a C123, and the following seems to
work:

  twl3025_reg_write(TOGBR1, 1 << 5); // turn ADAC on
  twl3025_reg_write(AUXDAC, 1000);
  delay_ms(1500);
  twl3025_reg_write(AUXDAC, 0);
  twl3025_reg_write(TOGBR1, 1 << 4); // turn ADAC off

Best regards,
  Dieter
