Subject: [PATCH 7/8] clocksource/drivers/timer-atmel-tcb: allow selecting first divider
Date: Thu, 10 Oct 2019 00:40:05 +0200 [thread overview]
Message-ID: <20191009224006.5021-8-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20191009224006.5021-1-alexandre.belloni@bootlin.com>
The divider selection algorithm never allowed to get index 0. It was also
continuing to look for dividers, trying to find the slow clock selection.
This is not necessary anymore.
