gain_ramp_rate
Controls the speed of the gain ramping when
ramping is activated
0 = nominal rate * 8
1 = nominal rate
2 = nominal rate / 8
3 = nominal rate / 16 (slowest)
The nominal rate (excluding headphone circuits) =
0.88 ms/dB. The nominal rate for the headphone
circuits is = 1.3 ms/dB.

0 = No resynchronisation. If the DAI drifts with
respect to the system clocks, either a sample is
skipped or it is double-sampled
1 = Automatic resynchronisation if the DAI drifts
with respect to the system clock
Controls the filter operation when the DAI is not
0x0
enabled or when no DAI clocks are available on the
ADC to DAC processing path
0 = Filters are synchronised to the DAI
1 = Filters are free running
