Encoding of baudrate divisor and subdivisor

[Bas van Dijk <v.dijk.bas@xxxxxxxxx>]

Hello,

I'm trying to understand how the baudrate divisor and subdivisor are
encoded in the value and index fields of a 'SIO_SET_BAUDRATE_REQUEST'
control request.

I looked at the 'ftdi_convert_baudrate' function which does the actual
encoding but failed to understand how the encoding really works.

What I basically want to know is given a divisor for example: 3 and
subdivisor: 0.125 (1/8) how these values are encoded in the value and
index fields.

Thanks,

Bas
