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.
