Subject: [PATCH v5 18/21] MIPS: qi_lb60: Use 750 kHz system timer & enable clocksource
Date: Wed, 25 Jul 2018 01:19:55 +0200
Message-Id: <20180724231958.20659-19-paul@crapouillou.net>
In-Reply-To: <20180724231958.20659-1-paul@crapouillou.net>
References: <20180724231958.20659-1-paul@crapouillou.net>
List-ID: <linux-clk.vger.kernel.org>

The default clock (12 MHz) is too fast for the system timer, which fails
to report time accurately.
