You could take the opportunity to reshuffle icestorm and firestorm while you're at it. Cheers, Conor. > - arm,arm710t > - arm,arm720t > - arm,arm740t > -- > 2.46.0 >

(Same goes for the watchdog, pinctrl and cluster-cpufreq bindings) I am not actually sure what is the right thing to do here. It seems that these bindings are originally sorted using SoC types (desktop or mobile) and generations. But then again I have looked at some other in-tree bindings from asahi, and it seems to be a mix of alphabetical and logical sorting in the way mentioned above. Maybe we can get some clarification from an Asahi Maintainer? For the soc-level machine compatibles though, I believe that should be retaining the logical order instead of trying to use alphabetical order. > > Cheers, > Conor. > >> - arm,arm710t >> - arm,arm720t >> - arm,arm740t >> -- >> 2.46.0 >> Nick Chan

Add the following CPU cores: - apple,cyclone: A7 cores - apple,typhoon: A8 cores - apple,twister: A9 cores - apple,hurricane-zephyr: A10 logical cores - apple,monsoon: A11 performance cores - apple,mistral: A11 efficiency cores In the Apple A10, there are physical performance-efficiency cores that forms logical cores to software depending on the current p-state, and only one type of core may be active at one time.
