Comment # 56 on bug 73338 from Chernovsky Oleg

And another one:

I see the values like this on my BONAIRE:
>W 4 587.343959 2 0xf0800200 0xc0300068 0x0 0 // it's CG_FDO_CTRL1
>R 4 587.343962 2 0xf0800204 0x40252f87 0x0 0 
>W 4 580.364670 2 0xf0800200 0xc0300064 0x0 0 // CG_FDO_CTRL0
>W 4 580.364671 2 0xf0800204 0x1814351 0x0 0  // I'm setting speed 50%
>W 4 594.360662 2 0xf0800200 0xc0300064 0x0 0 // CG_FDO_CTRL0 again
>W 4 594.360663 2 0xf0800204 0x1814387 0x0 0  // I'm setting speed 100%

Are you sure the FDO_STATIC_DUTY_MASK and FMAX_DUTY100_MASK is 0xF and not
0xFF?
