From mboxrd@z Thu Jan 1 00:00:00 1970 From: ldewangan@nvidia.com (Laxman Dewangan) Date: Wed, 20 Mar 2013 19:14:29 +0530 Subject: [PATCH 3/4] ARM: tegra: dalmore: add dt node for TPS65090's regulators In-Reply-To: <1363787070-14801-1-git-send-email-ldewangan@nvidia.com> References: <1363787070-14801-1-git-send-email-ldewangan@nvidia.com> Message-ID: <1363787070-14801-4-git-send-email-ldewangan@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org NVIDIA's Tegra114 platform, Dalmore, uses the TPS65090 as secondary PMICs which mainly act as voltage switch controlled by I2C communication. Add regulator node for this device.
