From d17adfdb17fb9f182d1fc5189d4772cd03f187c3 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 25 Jan 2012 14:43:27 -0700 Subject: ARM: dt: Add binding for Tegra PMC The Tegra PMC (Power Management Controller) interfaces with an external PMU (Power Management Unit), and controls wake-up from sleep modes. This initial binding is the bare minimum required to control the PMC's inversion of the PMU's interrupt signal.
