[PATCH v2 0/7] soc: qcom: Allow COMPILE_TEST of all drivers

[PATCH v2 0/7] soc: qcom: Allow COMPILE_TEST of all drivers

[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.


Changes since v1:
Added two new patches, "ASoC: qdsp6: Add depends on OF"
and "soc: qcom: Remove bogus depends on OF".
Patch "soc: qcom: Allow COMPILE_TEST of all drivers"
now adds "depends on ARCH_QCOM || COMPILE_TEST" to the menu entry.

[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.

Add "depends on ARCH_QCOM || COMPILE_TEST" to the menu entry,
that way we can avoid adding it to every single Kconfig.

Remove the existing depend 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.

Is it sensible that of_platform_device_destroy() is only defined when
building with CONFIG_OF=y?

I'm redirecting that question to the device tree maintainers.

There are a few of_* functions in include/linux/of_platform.h
that are only defined when CONFIG_OF=y:

of_platform_device_create()
of_platform_device_destroy()
of_platform_bus_probe()
of_device_alloc()

Rob, Frank, do you want me to create static inline dummy versions of these?

Niklas

No, because generally you should not be using these functions
directly. Yes, there are some users, but if you look at the tree,
there are few or isolated (PowerPC) users. Using
of_platform_populate/of_platform_depopulate is preferred.

of_platform_device_destroy() is also used by sound/soc/qcom/qdsp6/*
which is why I suggested this patch:
https://marc.info/?l=alsa-devel&m=152932497413567
that adds "depends on OF" for SND_SOC_QDSP6 in sound/soc/qcom/Kconfig.

Or do you think that a better solution would be to modify
sound/soc/qcom/qdsp6/* so that it instead uses
of_platform_populate()/of_platform_depopulate()?
(Or perhaps this isn't even an option,
I'm not at all familiar with the QDSP6 code).

Niklas

Yes, that is preferred. However, that won't work here because the
child nodes don't have compatible strings. Maybe we should add them as
this all just went in. That would also allow DT based module
autoloading to work (which I don't think would currently). Really, as
is, of_platform_device_create isn't needed here and you could just use
platform_device_register_simple instead. The child driver would have
to get the DT node pointer from the parent device instead.

But if you want to add empty functions for just
of_platform_device_{create,destroy}, I guess that is fine.

compatible was the reason why I started using 
of_platform_device_{create,destroy} apis. As you said we could also do 
it with simple platform device too.

I think adding compatible seems to be better option here along with 
of_platform_populate()/of_platform_depopulate(), I will try this!
