+ The LED1202 is a 12-channel low quiescent current LED controller
+ programmable via I2C; The output current can be adjusted separately
+ for each channel by 8-bit analog and 12-bit digital dimming control.
+ Datasheet available at
+ https://www.st.com/en/power-management/led1202.html

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.
