[PATCH 0/2] thermal: broadcom: Add NSP Thermal Support

[PATCH 0/2] thermal: broadcom: Add NSP Thermal Support

[Jon Mason]

This adds support for NSP to the existing Northstar thermal driver.
This code is based on patches currently in the Linux SoC Thermal git
tree.  Specfically,
https://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git/commit/?h=linus&id=a94cb7eeecc4104a6874339f90c5d0647359c102

[PATCH 1/2] thermal: broadcom: Allow for NSP to use ns-thermal driver

[Jon Mason]

Change the iProc Kconfig to select THERMAL and THERMAL_OF, which allows
the ns-thermal driver to be selected via menuconfig.  Also, change the
ns-thermal driver to work on any iProc based SoC.  Finally, tweak the
Kconfig description to mention support for NSP and make the default on
for iProc based platforms.

It would be better if this is split and sent through your arch tree, to
avoid conflicts. I could also pick it if you get an ack from one of your
maintainers. Still, first option is preferable.

Sure, I'll be happy to split this off.  I should've thought to split
it up before sending.  Thanks for the suggestion.

IIUC, my original default works, as we have used it frequently in
other places in the kernel.
grep -rI "default ARCH_BCM_IPROC" * | wc -l
15

However, if the above is preferred (or the other 15 massively broken),
I'll be happy to do it that way.

Naa, just trying to be more concise, while adding the NSP products to
the list..  BCM47094 is a type of BCM4709.  So, it is still there :)

Your construction is syntactically correct. Maybe might still work (did
not check myself) for the purpose you describe, but the construction
mentioned in Documentation/kbuild/kconfig-language.txt is:
 +      default y if BAR

So, please fix it.

Apologies. I think I either read too fast, or my fingers were faster
than my brain. Sorry.

Yeah... Are you sure they are all correct?

Your construction is syntactically correct. Maybe might still work (did
not check myself) for the purpose you describe, but the construction
mentioned in Documentation/kbuild/kconfig-language.txt is:
 +      default y if BAR

So, please fix it.

Oh, thanks for the info.  I was unaware of this, and we should
definitely follow the documentation..  I'll make the relevant changes
and do follow-on patches to correct the other places.
