description:
Note that a driver will take the lowest of all LED limits
since the chip has a single global setting. The lowest value
will be chosen due to the PWM specificity, where lower
brightness is achieved by reducing the duty-cycle of pulses
and not the current, which will always have its peak value
equal to led-max-microamp.
