From 9a716579660aa87a4ab4b4d1cac0686fba3707ba Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 13 Dec 2013 17:31:03 +0100 Subject: [PATCH] ARM: tegra: Add Tegra124 powergate support Three new gates have been added for Tegra124: SOR, VIC and IRAM. In addition, PCIe and SATA gates are again supported, like on Tegra20 and Tegra30.
