Filename based on compatibles (more or less), so could be:
st,m41t80.yaml
or:
st,m41txx.yaml
The "rtc" name can be skipped as it is implied from subsystem folder,
unless st,m41txx is a name of some SoC?
It's dedicated I2C RTC, a discrete soic8 chip with optional coin cell
battery.
We cannot really call it m41txx because there are other m41txx chips
with different register layouts and thus different RTC drivers:
next$ ls -1 drivers/rtc/*m41t*
drivers/rtc/rtc-m41t80.c
drivers/rtc/rtc-m41t93.c
drivers/rtc/rtc-m41t94.c
The m41t80 is a sane choice, the m41t80 was the first supported, the
other chips are just compatible to it.
Whether I should drop the rtc- prefix or not, I will defer that
preference to Alexandre .
