Dear All,
This came out of a discussion about Michael's variable gain amplifier
driver the other day. We have devices that have a channel that we
can't actually read, but know other things about. (there are other
cases that we have previously fudged around).
Anyhow, here is the promised series making the value optional.
Has recieved limited testing and I may well have fried someones
driver so please do take a look and test test test!
Dependent on the IIO_CHAN removal series.
Note I'll probably handle this set a little differently from
usual and send the first 9 to Greg asap, but hold the 10th
that actually makes them active until I'm sure there aren't
any drivers going to cross with it and end up broken.
Jonathan

This will allow us to have drivers where the channel value
may not be read or written but other information is available.

Until now all channels have had read/write attributes. This patch
allows for channels where we can't actually read the value (or for
output devices, write it!)

I think it would make sense to introduce both IIO_CHAN_INFO_RAW and
IIO_CHAN_INFO_PROCESSED. This will certainly make the code more simpler and
it also allows drivers to export both processed and raw values.

Good point. I thought abouting using the two bits for the single entry
for this, but you
are right, simply having a separate entry would be cleaner and only
waste a couple
of bits of the mask... which we were wasting before anyway and allows us
to drop the
separate flags for it. I'll rework the set with that... your naming
suggestion works as well.
