Maybe this can be noted in the commit description. What I am not sure how this magically defines the output as reg=<1> or if we have to swap reg number definitions in the DT. But encoder-tfp410.c and encoder-tpd12s015.c seem to do it the same way, so it is very likely that it works as defined. > which should get merged in v4.20. Well, I had hoped our bug fix makes it into v4.19 and can be potentially backported to stable. Do you plan to backport you patch? It seems to be quite independent and should apply to older releases.
