From 80d6737b27bbdf645a815c136606836b435f0268 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Thu, 28 Apr 2016 19:03:40 -0300 Subject: leds: gpio: Support the "panic-indicator" firmware property Calling a GPIO LEDs is quite likely to work even if the kernel has paniced, so they are ideal to blink in this situation. This commit adds support for the new "panic-indicator" firmware property, allowing to mark a given LED to blink on a kernel panic.
