From mboxrd@z Thu Jan 1 00:00:00 1970 From: simon.guinot@sequanux.org (Simon Guinot) Date: Mon, 23 Feb 2015 14:02:03 +0100 Subject: [PATCH] ARM: Kirkwood: enable GPIO fan alarm support for 2Big Network v2 Message-ID: <1424696523-14855-1-git-send-email-simon.guinot@sequanux.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On the LaCie 2Big Network v2 (net2big_v2) board, the fan alarm is not wired to the I2C fan controller but to a separe GPIO. This GPIO can be controlled by using the gpio-fan driver. This patch adds the gpio-fan alarm description in the net2big_v2 DTS.
