leds: triggers: Allow to switch the trigger to "panic" on a kernel panic

2016-05-06T08:22:09+00:00

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.

leds: trigger: Introduce a kernel panic LED trigger

2016-03-30T09:16:39+00:00

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.
