This patch series adds support for ADT7481 in lm90.c driver and extends the
device-tree options for it.
The ADT7481 is quite similar to MAX6696 (already supported in lm90) so a lot of
code is reused.
One major problem in fitting the ADT7481 in lm90.c is the chip detection.
However it seems that the chip has been designed and produced with correct
values at locations: 0xfe (manufactured id) and 0xff (chip id), but this is not
documented in the datasheet.
Before we go too far along this route, would you mind using my own patch series
as base to implement the devicetree changes ? I had prepared an extensive
patch series a while ago, adding not only support for ADT7481 but for
several other chips as well, I just never got around to sending it out.
I made my lm90 patch series available in branch hwmon-lm90 of
git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git
The patches in this series were module tested and tested on real hardware
with the test scripts at git@xxxxxxxxxx:groeck/module-tests.git;
look for scripts/lm90-real.sh and scripts/lm90.sh.
