Subject: [PATCH v2 04/12] clocksource: sp804: silently ignore secondary instaces
Date: Thu, 12 Oct 2017 12:26:50 +0200 [thread overview]
Message-ID: <20171012102658.17104-4-l.stach@pengutronix.de> (raw)
In-Reply-To: <20171012102658.17104-1-l.stach@pengutronix.de>
When probing from an upstream DT, we don't always have influence on
how many timer instances are enabled. Just use the first one and
silently skip the other instances.
