This LED controller has a driver under development which is currently being reviewed by the respective kernel maintainers. They are currently on v11 which is included here. 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 If the led node is present in the controller then the channel is set to active. The output current can be adjusted separately for each channel by 8-bit analog (current sink input) and 12-bit digital (PWM) dimming control. The LED1202 implements 12 low-side current generators with independent dimming control. 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.
