| 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. |
