I just tried 4.2-rc2 and I can't see any of the problems you have:

[    2.473968] twl_rtc 48070000.i2c:twl@48:rtc: Power up reset detected.
[    2.481170] twl_rtc 48070000.i2c:twl@48:rtc: Enabling TWL-RTC

...

The only thing I noticed is, that the display is not working.
For some reason it is not enabled:

disabled
