Why do you add clocks in the middle? The order is strict, so you just broke all DTS.
In DTS file, I only need to make sure that the order in clocks should be the same as clock-names, so I misunderstood that I can add the clock in the middle based on the clock type.
Sorry, I didn't know the order is strict. I will move the new clock to the last one in v2.
Actually, doing that is borderline-ok... there's no devicetree for MT8188 upstream, so that's not breaking anything at all. In any case, I agree that you should generally avoid doing that but I think that in this specific case it's fine; I'm not a devicetree maintainer though.
P.S.: Trevor, next time please make reviewers aware of the fact that no 8188 devicetree is present upstream!
Got it. Thanks.
Hi krzysztof,
Because there is no upstream mt8188 DTS, should I move the new clock to the end of clock list?
If I move "apll1_d4" to the end of the list at binding file, when I upstream the devicetree node existing clocks and clock-names properties , should I follow the sequence defined in dt-bindings or can I have a new sequence based on the clock type or alphabet?
Thanks, Trevor
