Convert the mpr121 binding to DT schema format using json-schema. Signed-off-by: Michal Vokáč <michal.vokac@xxxxxxxxx> --- Hi Rob, I will appreciate your help converting this binding. Currently the scheme is not valid and the error output of dt_binding_check is not really helpful. Also, who shoud be the maintainer of this binding? I put Dmitry in there as he is the input subsystem maintainer but I am not sure it is correct.
