Subject: of: add vendor prefix for Abracon Corporation
This series adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC
chip. Unlike many RTC chips, it includes an internal oscillator which
spares room on the PCB. It also has some interesting features, like
battery low detection (which the driver in this series supports). The
only small "limitation" (mainly due to what RTC subsystem expects from
RTC chips) is the fact that its alarm is accurate to the second. This
series provides a solution (described below) for that limitation using
another mechanism of the chip.
I decided to split support between three different patches for
this v0:
- Patch 1/3: it simply references Abracon Corporation in vendor-prefixes
documentation file. As Abracon has no NASDAQ ticker symbol; I have
decided to use "abcn" (I initially started my work w/ "ab" but later
changed for "abcn" which looked more meaningful)
- Patch 2/3: it adds initial support for the chip and provides the
ability to read/write time and also read/write alarm. As the alarm
the chip provides is accurate to the minute, the support provided
by this patch also has this limitation (e.g. UIE mode is not
supported).
- Patch 3/3: the chip supports a watchdog timer which can be used to
extend the alarm mechanism in patch 2/3 in order to provide support
for alarms under one minute (e.g. support UIE mode). In practice,
the logic I implemented is to use the watchdog timer for alarms which
are at most 4 minutes in the future and use the common alarm mechanism
for alarms which are set to larger values. With that additional patch
the device fully passes the rtctest.c program.
I decided to split the driver between two patches (2 and 3 of 3) in
order to ease review: patch 2 should be pretty straightforward to read
for someone familiar w/ RTC subsystem. Patch 3 only extends what is in
patch 2 regarding alarms.
