- * linux/arch/arm/kernel/leds-sa1100.c
- *
- * Copyright (C) 2000 John Dorsey <john+@cs.cmu.edu>
- *
- * Original (leds-footbridge.c) by Russell King
- *
- * Added Brutus LEDs support
- * Nicolas Pitre, Mar 19, 2000
- *
- * Added LART LED support
- * Erik Mouw (J.A.K.Mouw@its.tudelft.nl), April 21, 2000
- *
- *
- * Assabet uses the LEDs as follows:
- * - Green - toggles state every 50 timer interrupts
- * - Red - on if system is not idle
- *
- * Brutus uses the LEDs as follows:
- * - D3 (Green, GPIO9) - toggles state every 50 timer interrupts
- * - D17 (Red, GPIO20) - on if system is not idle
- * - D4 (Green, GPIO8) - misc function
- *
- * LART uses the LED as follows:
- * - GPIO23 is the LED, on if system is not idle
- * You can use both CONFIG_LEDS_CPU and CONFIG_LEDS_TIMER at the same
- * time, but in that case the timer events will still dictate the
- * pace of the LED.
