This note is no longer true. Marek tested it on his M28EVK, Lothar on his T=
X28=20
and myself also on an i.MX28EVK.
=46or the IIO part of the driver I tested on my i.MX23 based ChumbyOne and =
some=20
customer hardware and it seems still to work (I can only guess if the value=
s I=20
read from the sysfs entries are correct, sorry).
