Problem:
This interface is added to facilitate debugging the voltage-
table in pwm regulator, which can output different percentages
of waveforms in a fixed pwm cycle.
example:
echo 50 100 > sys/class/pwm/pwmchipx/pwmx/relative_duty
output 50% duty pwm
Solution:
add relative_duty interface in pwm sysfs
