Currently the time can only be read. Setting the time must be done
through sending a report, which currently isn't supported by
hid-sensor-hub.
It is necessary that all values like year, month etc, are send as
8bit values (1 byte each) and all of them in 1 report. Also the
spec HUTRR39b doesn't define the range of the year field, we
tread it as 0 - 99 because that's what most RTCs I know about are
offering.
I don't think we should register a IIO device for this. Just an RTC
device
should be fully sufficient.
You would have to implement all the used services hid-sensor-hub offers
in the rtc-driver again.
Besides that, time is part of the spec for HID sensors, which makes
sense. Making that available as a RTC to read/set the time is imho the
best to way support that. If you want a driver which doesn't use the HID
sensor hub framework (or iio), you would either have to define your own
standard or make sure it is interoperable with the HID sensor hub
framework, which might not be trivial.
