Subject: [PATCH v2 2/3] devicetree: leds: Introduce "panic-indicator" optional property
Date: Wed, 13 Apr 2016 15:08:18 -0300 [thread overview]
Message-ID: <1460570899-24642-3-git-send-email-ezequiel@vanguardiasur.com.ar> (raw)
In-Reply-To: <1460570899-24642-1-git-send-email-ezequiel@vanguardiasur.com.ar>
It's desirable to specify which LEDs are to be blinked on a kernel
panic. Therefore, introduce a devicetree boolean property to mark
which LEDs should be treated this way, if possible.
