From 18db4fe09886691a781f3d1e4589ede0239d8ee2 Mon Sep 17 00:00:00 2001 From: Omar Ramirez Luna Date: Tue, 21 Feb 2012 20:46:20 -0600 Subject: [PATCH] staging: tidspbridge: always compile dsp wdt code In order to detect it at runtime, we need the code handling wdt clock available at runtime to decide whether to enable or disable based on the baseimage symbols. Default timeout has been set to 5 seconds. Downside is that we will lose the option to set a custom timeout for overflow, but than can be added (if needed) as part of debugfs.
