Hi Guillaume,
I'm afraid we decided a month or so back that all new dt bindings proposed
for IIO drivers should be in yaml format.
Please reformat this appropriately for v2 and make sure to run
make dt_bindings_check.
There are a few examples in tree already, but we are deliberately
not converting existing bindings too quickly to avoid overloading
reviewers.
Thanks,
Jonathan
