From c33a15974c1a326b0034cc2a2e73fac92ae8d001 Mon Sep 17 00:00:00 2001 From: Andrew Chew Date: Fri, 14 Feb 2014 12:03:05 -0800 Subject: watchdog: Add tegra watchdog Add a driver for the hardware watchdogs in NVIDIA Tegra SoCs (Tegra30 and later). This driver will configure one watchdog timer that will reset the system in the case of a watchdog timeout. This driver binds to the nvidia,tegra30-timer device node and gets its register base from there.
