The led child reg node is the index within the bank, document that and update the example accordingly. The reg property in child node is limited to 0-2 since there are 3 leds per bank, previous value in example was speculative.

The LP50XX is multi-channel, I2C RGB LED Drivers that can group RGB LEDs into
|
|
a LED group or control them individually.
|
|
|
|
The difference in these RGB LED drivers is the number of supported RGB
|
|
modules.
