[PATCH v11 0/3] Add LED1202 LED Controller
From: Vicentiu Galanopulo
Date: Wed Dec 18 2024 - 13:34:20 EST
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.
