I agree with that approach - need a way to describe the upstream
hardware - so
will need a thermistor driver
Actually I'm not 100% happy with the above solution myself, because
if we
start supporting devices that act as an iio-multiplexer (some device
that
is an iio consumer and provides many new iio channels and can
control
via gpios which of it child channels is actually routed to the
upstream
device) I don't know how to properly manage the regulator device.
Hmm. Are you talking about muxing the regulator as well? That will
get
complex indeed. Might be possible to cheat and imply the regulators
are
always connected to all inputs... or do you want to dynamically
change
the regulator output? That gets messy fast - though in theory might
be
possible...
Yes, that's a good summary of what I'm thinking. As there is no
iio-multiplexer yet, this is sort of an academic question. But it's
kind of an obvious thing to want, so we shouldn't be surprised when
somebody actually starts working on that.
Thanks,
Harald
