Subject: [PATCH 1/5] rtc: imxdi: set range
Date: Tue, 16 Apr 2019 10:34:28 +0200 [thread overview]
Message-ID: <20190416083432.14483-1-alexandre.belloni@bootlin.com> (raw)
The RTC Time Counter MSB Register contains the 32 most significant bits
(47:16) of the 47-bit RTC Time Counter. Clocked by a 32.768 KHz clock, this
register is effectively a 32-bit seconds counter.
