+description:
+ The BD2606 MVV is a programmable LED controller connected via I2C that can
+ drive 6 separate lines. Each of them can be individually switched on and off
+ but the brightness setting is shared between two of them.

Maybe add a link to data-sheet?
https://fscdn.rohm.com/en/products/databook/datasheet/ic/power/led_driver/bd2606mvv_1-e.pdf

According to the data-sheet, BD2606 has an enable-pin. Should it be visible in the bindings?
