From mboxrd@z Thu Jan 1 00:00:00 1970 From: ldewangan@nvidia.com (Laxman Dewangan) Date: Sat, 6 Jul 2013 14:44:29 +0530 Subject: [PATCH V2] ARM: tegra: enable gpio-keys on dalmore Message-ID: <1373102069-5641-1-git-send-email-ldewangan@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Dalmore have the keys mounted on board which are connected to different pins of Tegra. Add the keys entry in DTS file to enable key functionality. This will enable KEY_POWER, KEY_HOME, KEY_VOLUMEUP and KEY_VOLUMEDOWN.
