The lp5860 is a LED matrix driver with 18 constant current sinks and 11
scan switches for 198 LED dots:
* Supply range from 2.7 V to 5.5 V
* 0.1mA - 50mA per current sink
* 1MHz I2C and 12MHz SPI control interface
* 8-bit analog dimming
* 8/16-bit PWM dimming
* individual ON and OFF control for each LED dot
* globat 3-bit Maximum Current setting for all LED dots
* individual LED dot open/short detection

I'm not really sure what you're attmpting here with the minItems: 1, maxItems: 12. Are you sure you didn't mean maxItems: 1, minimum: 1, maximum: 12?
