From d8fec1fc80cd8639449e2b5012688f5be109eeaf Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 4 Jan 2011 21:28:18 +0100 Subject: MIPS: ath79: add common GPIO LEDs device Almost all boards have one or more LEDs connected to GPIO lines. This patch adds common code to register a platform_device for them. The patch also adds support for the LEDs on the PB44 board.
