Subject: [PATCH v6 8/9] clocksource/drivers/timer-atmel-tcb: allow selecting first divider
Date: Sat, 11 Jul 2020 01:08:12 +0200 [thread overview]
Message-ID: <20200710230813.1005150-9-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20200710230813.1005150-1-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.
