Subject: Re: Raw data block input: is IIO a good choice?

Hi Jonathan,

I tried to describe all channels, and it turns out many of them cannot
be adequately described by the types in iio_chan_type. How do I
describe the message sequence number? How about the control register
value at the time when the data was captured? That data needs to be
passed to the userspace.

I checked sca3000 driver. I see that it uses
sca3000_read_first_n_hw_rb() to read the data from the buffer. Can
that data be accessed by the userspace as is, without any processing?

Pavel
