Subject: [PATCH v2 1/3] clocksource: tegra: Add nvidia,tegra30-timer compat
Date: Mon, 3 Feb 2014 16:17:33 -0800 [thread overview]
Message-ID: <1391473055-3158-2-git-send-email-achew@nvidia.com> (raw)
In-Reply-To: <1391473055-3158-1-git-send-email-achew@nvidia.com>
There are some differences between tegra20's timer registers and tegra30's
(and later). For example, tegra30 has more timers. In addition, watchdogs
are not present in tegra20.
Add this compatibility string in order to be able to distinguish
whether the additional timers and watchdogs are there or not.
