Subject: [PATCH 6/6] rtc: r9701: set range
Date: Thu, 15 Oct 2020 21:11:35 +0200	[thread overview]
Message-ID: <20201015191135.471249-6-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20201015191135.471249-1-alexandre.belloni@bootlin.com>

Set range and remove the set_time check. This is a classic BCD RTC.
