This chip expands the freqency field from 3 to 4 bits, to
add more frequencies in the 22.5 to 30 kHz ranges.

SMSC EMC6D103S is similar to EMC6D103, but does not support pwm#_auto_pwm_minctl
and temp#_auto_temp_off.
+The LM96000 supports additional high frequency PWM modes (22.5 kHz, 24 kHz,
+25.7 kHz, 27.7 kHz and 30 kHz), which can be configured on a per-PWM basis.
