I ran "make dt_binding_check" in my local environment and don't see the failures. The 2 properties are introduced in this patch set and I add the properties in aspeed-g4/5/6 dtsi files (patch #4, #5 and #6): am I missing something? Sorry I forgot to add you when including the dt-binding document to the series v4: will add you and all dt binding maintainers in v5 soon. Cheers, Tao
