Hello,
On a recent disussion [0] with Krzysztof Kozlowski and Laxman Dewangan,
we came to the conclusion that the max77686 and max77802 RTC are almost
the same with only a few differences so there shouldn't be two separate
drivers and is better to extend max77686 driver and delete rtc-max77802.
By making the driver more generic, other RTC IP blocks from Maxim PMICs
could be supported as well like the max77620.
Patches #1 is just a trivial cleanup.
Patch #2 allows to support RTCs that need a shorter delay when updating
the RTC.
Patch #3 adds a driver data structure to avoid hard-coding parameters
specific to a certain RTC such as the needed delay and RTC register mask.
Patch #4 changes the driver to use a mapping table instead of using the
max77686 registers offsets directly to allow supporting RTC with other
registers addresses and layout.
Patch #5 Adds support for max77802 to max77686 RTC driver and patch #6
removes the old driver since is not needed anymore.
Finally patch #7 and patch #8 removes the Kconfig symbol from defconfigs.
I've tested this patch-set on an Exynos5800 Peach Pi Chromebook that has
a max77802 PMIC and the RTC was working correctly but I don't have a
machine with max77686 so I will really appreaciate if someone can test
that no regressions were introduced.
Thanks for the submission. I like the approach. I'll start reviewing the
code and testing it... or maybe I'll wait with testing for v2 because I
already sent some comments. :)
Anyway I will provide later tested-by on max77686.
Thanks a lot for your detailed review. I'll post v2 shortly so you can
just test that.
Best regards,
Krzysztof
