Subject: staging:iio:light Add IIO_CHAN_INFO_RAW/PROCESSED entries to all drivers.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=90354d0038e9e3d82d5fee5442d48f7cafb96a0c;p=deliverable%2Flinux.git

staging:iio:light Add IIO_CHAN_INFO_RAW/PROCESSED entries to all drivers.

Precursor to making value read / write attribute optional.
Note that minimal change route taken here. The read_raw callbacks
in both drivers could do fewer checks to identify the channel than
they now do.
