So you mean that RTC register +0x160 controls the system HOSC clock, so the main input clock for all the PLLs and other clocks? And by clearing bit 1 in there we can stop this? And if that is the case, do you suggest that we should model this in the DT, so that the fixed-clock "<&osc24M>" should be replaced with "<&rtc 3>"? So from a "the DT describes the hardware" point of view that would probably the right way, but not sure if Linux is happy about that. At the very least that would mean to extend the RTC driver to export a fourth clock, and all devices would now depend on the RTC (also for probing!). And Linux can realistically never turn that clock off anyway (without grinding to a halt), so this register is more useful for ARISC firmware? So I am somewhat undecided: changing this for the H6 would make newer DTs unusable on older kernels, without anything we really gain. When we really want this, we should indeed use the opportunity to introduce this at least for the H616 from day one, to avoid this situation here. But this requires more changes than just the binding, doesn't it?
