Hi all

I did some more testing as I could not understand this bugfix:

3769a375ab83 rtc: pcf2127: bulk read only date and time registers.

This fix seems to be incomplete as root cause is not auto-increment
read aka bulk read, but reading control register 2 triggers zero value
in WD_VAL resulting in stopped watchdog until systemd kick the dog
again :)

As the watchdog has 2 control registers I will do some more testing
to see if this also apply to the other register. But more importantly
this issue also affect timestamp0_{store,show} functions in tamper
detection support, and I will therefor send a v2 of the patch series.
