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

All applied now, I had to rebase the last patch on top of v4.12-rc1

Thanks!
