+Subject: [PATCH 029/110] MIPS: BCM47XX: Prepare support for LEDs
+
+So far this is mostly just a proof of concept, database consists of a
+single device. Creating a nice iterateable array wasn't an option
+because devices have different amount of LEDs. And we don't want to
+waste memory just because of support for a device with dozens on LEDs.
