Hi Fabrice,

I just noticed that since Jonathan question in v1.

Above ABI has been moved in the past as discussed in [1]. You can take a
look at:
b299d00 IIO: stm32: Remove quadrature related functions from trigger driver

Could you please remove the above chunk ?

With that, for the stm32 part:

Hmm... probably those were re-introduced due to a rebase. This

I'll drop those hunks.

Thanks!
Mauro
