2016-05-06leds: triggers: Allow to switch the trigger to "panic" on a kernel panicEzequiel Garcia1-0/+47
This commit adds a new led_cdev flag LED_PANIC_INDICATOR, which allows to mark a specific LED to be switched to the "panic" trigger, on a kernel panic. This is useful to allow the user to assign a regular trigger to a given LED, and still blink that LED on a kernel panic.

2016-03-30leds: trigger: Introduce a kernel panic LED triggerEzequiel Garcia1-0/+30
This commit introduces a new LED trigger which allows to configure a LED to blink on a kernel panic (through panic_blink). Notice that currently the Openmoko FreeRunner (GTA02) mach code sets panic_blink to blink a hard-coded LED. The new trigger is meant to introduce a generic mechanism to achieve this.
