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