Hi,

The change set is a little bigger than expected.  This is because that
half of the changes were for 5.2, but unfortunately they missed the
merge window.  So we have changes for two development cycles combined
here.  Please pull, thanks!

Shawn

An SoC info driver shouldn't need to be =y, I think? It exports no in-kernel
interfaces, so it should do just fine as a module.

And why does this need to be =y? Patch doesn't say.

Not merged until above is clarified.


Thanks!

Hmm, soc_device_match() comes out of SoC bus subsystem and will be used
by device drivers to identify SoC.

Sorry for not making it clear in the commit log.  This basically enables
the access to SoC fuses, where various system information are stored
there, like CPU speed grading which is needed by cpufreq support.

I will rework the patch by putting above info into commit log, and
resend the PR.

Ah, yes of course. But don't we usually use compatible for this?

Having hardware self-describe is nice, not having to populate DT
entries from the bootloader.

Yes, we do.  But soc_device_match() is now preferred over compatible,
since it can even identify the SoC revision while compatible usually
cannot.
