Subject: [PATCH 0/4] rtc: m41t80: improve SQW support
Date: Tue, 25 Apr 2017 16:45:13 +0200 [thread overview]
Message-ID: <20170425144517.15962-1-gary.bisson@boundarydevices.com> (raw)
Hi,
This series aims at improving the square-wave support for some of the
devices supported by the m41t80 driver.
The first two patches are fixes that prevent the driver from overriding
the SQW configuration (divider & enable bit).
Then the last two remove the old sysfs entry and replace it with a clock
provider approach.
It has been tested on a Boundary Devices Nitrogen6_MAX which features a
MicroCrystal RV4162 RTC. The SQW (named clkout in RV4162 datasheet) can be
probed on TP70 on the platform.
Let me know if you have any question/suggestion.
Regards,
Gary
