1057  * which is four times the baud base, and the prescaler increments in
1058  * steps of 1/8.  Therefore to make calculations on integers we need
1059  * to use a scaled clock rate, which is the baud base multiplied by 32
1060  * (or our assumed UART clock rate multiplied by 2).
1061  *
1062  * The allowed oversampling rates are from 4 up to 16 inclusive (values
1063  * from 0 to 3 inclusive map to 16).  Likewise the clock prescaler allows
1064  * values between 1.000 and 63.875 inclusive (operation for values from
1065  * 0.000 to 0.875 has not been specified).  The clock divisor is the usual
1066  * unsigned 16-bit integer.
1067  *
1068  * For the most accurate baud rate we use a table of predetermined
1069  * oversampling rates and clock prescalers that records all possible
1070  * products of the two parameters in the range from 4 up to 255 inclusive,
1071  * and additionally 335 for the 1500000bps rate, with the prescaler scaled
1072  * by 8.  The table is sorted by the decreasing value of the oversampling
1073  * rate and ties are resolved by sorting by the decreasing value of the
1074  * product.  This way preference is given to higher oversampling rates.
1075  *
1076  * We iterate over the table and choose the product of an oversampling
1077  * rate and a clock prescaler that gives the lowest integer division
1078  * result deviation, or if an exact integer divider is found we stop
1079  * looking for it right away.  We do some fixup if the resulting clock
1080  * divisor required would be out of its unsigned 16-bit integer range.
1081  *
1082  * Finally we abuse the supposed fractional part returned to encode the
1083  * 4-bit value of the oversampling rate and the 9-bit value of the clock
1084  * prescaler which will end up in the TCR and CPR/CPR2 registers.
