Subject: dt-bindings: leds: Add LED1202 LED Controller
|
|
|
|
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.

+description: |
|
|
+ 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.
