I recently (in another series - the IIO backend) went through some trouble = to actually not break ABI. Meaning, I had to do some not so neat hacking in th= e driver because Rob was more comfortable with not breaking ABI in DT. So, I assumed he would not like for me to break it in here. - Nuno S=C3=A1 >=20
