* Color conversion values have 3 separate fixed point formats:

* exp.mantissa (ee.mmmmmmmmm)

* eee = 101 = reserved
* eee = 110 = reserved
* eee = 111 = 10^0 (m.mmmmmmmm) (only usable for 1.0 representation)

* ee = 01 = 10^0 (m.mmmmm)

* ee = 11 = 10^2 (mmm.mmm)
*
* Simple conversion function:
*
* static u32
* float_to_csc_11(float f)
* {
* u32 exp;
* u32 mant;
* u32 ret;
*
* if (f < 0)

* Sub carrier DDA
*
* I think this works as follows:
*
* subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
*
* Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
*
* So,
* dda1_ideal = subcarrier/pixel * 4096
* dda1_inc = floor (dda1_ideal)
* dda2 = dda1_ideal - dda1_inc
*
* then pick a ratio for dda2 that gives the closest approximation. If
* you can't get close enough, you can play with dda3 as well. This
* seems likely to happen when dda2 is small as the jumps would be larger
*
* To invert this,
*
* pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
