Thanks.

Current limit of 16 will be exhausted by platforms specifying the frequency for 9 clocks using opp-hz, like Qcom SDM845 SoC. For instance, specifying the frequency for 9 clocks with 64bit specifier as below would consume (9 * 2 = 18) items. opp-50000000 { opp-hz = /bits/ 64 <50000000>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <37500000>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <75000000>; }; So let's increase the limit to 32 which should be enough for most platforms (hopefully).
