It looks like the second patch doesn't yet have the backing from the DT people, which prevents the remainder of the patch set progressing. That's the sticking point which needs to be resolved.Agreed. That is exactly the point for which I was seeking more feedback. OTOH, 7/8 and 8/8 may potentially work without the DT bindings, as they simply expose a sysfs attribute. If you, and others, see value in them, I can easily put them at the top of the series and post a v2. Thoughts?I've no idea, sorry. When it comes to stuff like CPU level power management, the hardware I have is very limited in its capabilities (no support even for S2RAM.) I've also never managed to get big.LITTLE working on my platforms that should support it.
No problem. Thanks a lot for your feedback anyway.
Eg, I gave up with the TC2 tile in Versatile Express. I forget the details, but getting it booting was exceedingly difficult, and no one really seemed interested in helping. So my TC2 tile is collecting dust while the CA9x4 tile lives in the platform - which is now part of the nightly build/boot test farm.
I guess I could provide some support for the TC2 bits, if you didn't yet give up completely on it :-). Please, don't hesitate to let me know, even privately, about that.
