The driver was just introduced by me in v6.11, I assume that the only user is a board that is not yet available in the upstream Linux kernel (we gonna send the DT soon), with that said I am relatively confident we are not going to break any user. The reason for sending this patch is that we just stumbled across a different driver that was hard-coding the IRQ flags and it was not working for our hardware, at that moment I realized that the decision on the just added ti-ads1119 was not the best one. The idea of this patch is to clean this up _before_ any user is affected. Francesco
