Subject: [PATCH 09/12] rtc: rx8025: set range
Date: Sun, 7 Nov 2021 23:54:54 +0100 [thread overview]
Message-ID: <20211107225458.111068-9-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20211107225458.111068-1-alexandre.belloni@bootlin.com>
Set the RTC range, it is a classic BCD RTC, with 00 being a leap
year. Let the core handle range checking.
