maintainers:
- Martin Kurbanov <mmkurbanov@sberdevices.ru>
description: |
It is a matrix LED driver programmed via an I2C interface. Devices have
a set of individually controlled leds and support 3 pattern controllers
for auto breathing or group dimming control. Supported devices:
- AW20036 (3x12) 36 LEDs
- AW20054 (6x9) 54 LEDs
- AW20072 (6x12) 72 LEDs
- AW20108 (9x12) 108 LEDs

Note that a driver will take the minimum of all LED limits
since the chip has a single global setting.
The maximum output current of each LED is calculated by the
following formula:
IMAXled = 160000 * (592 / 600.5) * (1 / max-current-switch-number)
And the minimum output current formula:
IMINled = 3300 * (592 / 600.5) * (1 / max-current-switch-number)
where max-current-switch-number is determinated by led configuration
and depends on how leds are physically connected to the led driver.
