[PATCH 0/5] soc: qcom: remove depends on ARCH_QCOM

[Niklas Cassel]

Since commit cab673583d96 ("soc: Unconditionally include qcom Makefile"),
we unconditionally include the soc/qcom/Makefile.

This opens up the possibility to compile test the code even when
building for other architectures.

This patch series prepares and enables all but two Kconfigs to be
compile tested even when building for other architectures.

[PATCH 3/5] soc: qcom: smp2p: Add select IRQ_DOMAIN

[Niklas Cassel]

Since we are using irq_domain_add_linear(), add a select on IRQ_DOMAIN.
This is needed in order to be able to remove the depends on ARCH_QCOM.

[PATCH 5/5] soc: qcom: Remove depends on ARCH_QCOM

[Niklas Cassel]

Since commit cab673583d96 ("soc: Unconditionally include qcom Makefile"),
we unconditionally include the soc/qcom/Makefile.

This opens up the possibility to compile test the code even when
building for other architectures.

Remove the depends on ARCH_QCOM for all Kconfigs, except for
two Kconfigs that depend on QCOM_SCM, since that triggers lots of build
errors in qcom_scm. However, that shouldn't stop us from removing
it from those where it is possible.

Argh, my git send-email scripts were too stupid to add Andy
and linux-arm-msm to this patch.

Some of the drivers in drivers/soc/qcom depended on this file.

Not sure if this patch should go via Andy's tree or Bjorn's.

Regards,
Niklas

Hello Andy

It seems like QCOM_APR is from Mark Brown's tree,
so just a heads up that you might get a conflict when applying.

Kind regards,
Niklas

Why do we want to do this when all of it is qcom specific?
Besides wouldn't this increase the binary size for other platforms

Sorry, my bad. Send the message without completing.

Besides above points, the COMPILE_TEST flag should allow you
to compile test all of these drivers. If COMPILE_TEST is missing
in some of the configs, we should try adding that.
Or, is there anything that I am missing here for the intention of this patch?

To be able to compile test drivers that select some of these Kconfigs,
even when building for other architectures.

The binary size shouldn't increase if they don't enable these Kconfigs.

That is another alternative.
So either make sure that all these Kconfigs
have "depends on ARCH_QCOM || COMPILE_TEST",
or
remove ARCH_QCOM from these Kconfigs.

A third, and perhaps best alternative is to do like
drivers/soc/mediatek/Kconfig

menu "MediaTek SoC drivers"
    depends on ARCH_MEDIATEK || COMPILE_TEST

Make sure that our root menu entry depends on ARCH_QCOM || COMPILE_TEST,
that way we could remove ARCH_QCOM for all Kconfigs.

Thoughts?

Niklas

Are these other drivers which select these Kconfigs not QCOM dependent?
We should make them so if that's not the case, and also add COMPILE_TEST
for them too.

To me the first and third approach look same. So I will leave it to Andy 
to decide
which is cleaner.
For 2nd option, I would still say that there shouldn't be a need for 
these drivers
to be compiled outside of the ARCH_QCOM, besides for compile test purpose.
