Laurent, Many thanks Laurent for your comment, I understood the merge of the two 1v2 power supplies but missed the "mandatory" part... maybe because this patch (with optional power supplies) already got the reviewed-by from Rob, I thought the discussion thread you pointed out was applicable "only" to totally new driver documentation. So, on my side, as a "new user" of sii902x IC, no problem to put these power supplies as mandatory instead of optional properties but I would like to be sure this is applicable to both old and new bindings doc : ) Rob, could you please confirm these power supply properties should be "mandatory"? if yes, should we then modify other optional properties like the reset-gpios too in the future?
