It was tested on a Renesas Lager board (R-Car H2) and the bindings were checked with 'dtbs_check' and the latest dtschema which also include SMBAlert additions[1]. The series is still marked RFC because I have one question left, see the annotations of patch 1. Looking forward to comments! Happy hacking...
