+
+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 pairs of them.
+
+  Datasheet is available at
+  https://fscdn.rohm.com/en/products/databook/datasheet/ic/power/led_driver/bd2606mvv_1-e.pdf
