| 70 | Note that a driver will take the lowest of all LED limits |
| 71 | since the chip has a single global setting. The lowest value |
| 72 | will be chosen due to the PWM specificity, where lower |
| 73 | brightness is achieved by reducing the duty-cycle of pulses |
| 74 | and not the current, which will always have its peak value |
| 75 | equal to led-max-microamp. |
