From mboxrd@z Thu Jan 1 00:00:00 1970 From: mperttunen@nvidia.com (Mikko Perttunen) Date: Wed, 18 Jun 2014 17:23:22 +0300 Subject: [PATCH v2 3/7] ARM: tegra: Add SATA and SATA power to Jetson TK1 device tree In-Reply-To: <1403101406-15439-1-git-send-email-mperttunen@nvidia.com> References: <1403101406-15439-1-git-send-email-mperttunen@nvidia.com> Message-ID: <1403101406-15439-4-git-send-email-mperttunen@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This enables the integrated SATA controller on the Tegra124 system-on-chip on the Jetson TK1 board and adds regulators for the onboard Molex connector commonly used to power SATA devices. The regulators are marked always-on since they can be used for other purposes than powering SATA devices.
