To clarify: there is almost no single binding using your style. Even if there is one, then 99 others are using it differently. Do not implement things entirely different than everyone else. This is the same for C code you send upstream. No difference here... Best regards, Krzysztof

Hi Dmitry, As we discussed during SM8650 camcc and videocc changes, the MMCX rail's minimum voltage level from cmd-db is adequate for these clock controllers to operate on SM8650. So, we removed the 'required-opps' property from their DT nodes. Although 'required-opps' will remain in the properties list, it’s not mandatory to be present in 'required:' list, as it is dependent on cmd-db minimum level. So, can I please go ahead and update these bindings to remove 'required-opps' from the 'required:' list, as done in v1 of this series. It seems unconventional to make 'required:' conditional based on the platform type. v1 link:- https://lore.kernel.org/all/rbej7rbjiwtgf4reiomtmlv3ef3ljfys5yfzypigrertylucu7@be3v65aeuimb/ Thanks, Jagadeesh > Best regards, > Krzysztof >

On SM8650, the minimum voltage corner supported on MMCX from cmd-db is sufficient for clock controllers to operate and there is no need to specify the required-opps. Hence remove the required-opps property from the list of required properties for SM8650 camcc and videocc bindings.
