Subject: [PATCH v2 0/3] Add RTC for MStar SSD20xD SoCs
Date: Wed, 13 Sep 2023 17:16:03 +0200 [thread overview]
Message-ID: <20230913151606.69494-1-romain.perier@gmail.com> (raw)
This patches series adds a new driver for the RTC found in the Mstar
SSD202D SoCs. It adds a basic rtc driver, the corresponding devicetree
bindings.
The rtctest (from selftests) has been passed on this driver, with the
following output:
# rtctest
TAP version 13
1..8
# Starting 8 tests from 1 test cases.
# RUN rtc.date_read ...
# rtctest.c:52:date_read:Current RTC date/time is 17/05/2023 15:58:12.
# OK rtc.date_read

Changes since v1:
- Changed the compatible from mstar,ssd20xd-rtc to mstar,ssd20d-rtc.
So the driver, its documentation and the commit messages have been
reworked accordingly.
- Re-worked the dt-binding, I have also simplified the commit message
- Re-worked the commit message for the driver
- Remove redundant logging message for the user in the driver, as
requested by the subsystem maintainer. As these messages are helpful
for debugging purpose, I have switched these to dev_dbg().
- Updated the list of maintainers (sorry for that).
