[Qemu-devel] [PATCH 00/14] Generalize Dallas/Maxim I2C RTC devices v3

[Michael Davidsaver <mdavidsaver@gmail.com>]

This series generalizes the ds1338 model to also support the ds1375.
As previously, only the time of day registers are modeled.  This
series (v3) is a minor iteration on the previous v2.

No changes were made to the unittests.

Summary of changes by patch name in response to comments by Peter Maydell.

= timer: ds1338 use registerfields.h

Changed as requested to be more direct translation.

= timer: ds1338 persist 12-hour mode selection

While it isn't clear from the diff, the condtional
involved has 3 arms, only two of these were updating
's->nvram[]'.  The arm handling control register
writes is the one which didn't.  So attempts to set
the 12 hour mode bit were ignored, and subsequent
reads always returned 24 hour time.

So this is a behaviour change, and a minor bug fix.

= timer: ds1338 clarify HOUR handling
= timer: ds1338 fix wday_offset handling

These two are combined as requested.

= timer: generalize ds1338

The change to CTRL register handling is split out
as a seperate patch "timer: ds1338 remove vestige of un-modeled OSF"

= timer: ds-rtc handle CENTURY bit

Changed as suggested.
