I'd say add an option "UseFWPLL" or something like that. When set,
probe the value of PPLL_REF_DIV and PPLL_DIV_n (where n is whatever
PPLL is selected in CLOCK_CNTL_INDEX low byte).
Then, set the existing:
- info->UseBiosDividers = 1;
- info->RefDivider (whatever is in PPLL_REF_DIV)
- info->FeedbackDivider = (PPLL_DIV_n & 0xffff);
- info->PostDivider = (PPLL_DIV_n >> 16);
Once that's set, the driver will use the existing x86 "BIOS divider"
bypass when setting mode and will use those values.
