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.
