Referencing directly dpll-pin nodes and using their phandles in consumers is at least unusual. The right approach should be referencing dpll-device and use cells to specify the dpll pin that is used. Also Krzysztof mentioned there are missing update of supplier_bindings in drivers/of/property.c to ensure that proper dev_links between producer and consumer are created. I will send a v2 of this patch-set with addressed another issues found by patchwork bot and including the DT schema (this patch) to review if it is ok. Thanks, Ivan
