The LED1202 is a 12-channel low quiescent current LED driver with: * Supply range from 2.6 V to 5 V * 20 mA current capability per channel * 1.8 V compatible I2C control interface * 8-bit analog dimming individual control * 12-bit local PWM resolution * 8 programmable patterns Internal volatile memory allows the user to store up to 8 different patterns, each pattern is a particular output configuration in terms of PWM duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but common to all patterns. Each device tree LED node will have a corresponding entry in /sys/class/leds with the label name. The brightness property corresponds to the per channel analog dimming, while the patterns[1-8] to the PWM dimming control.
