Subject: [PATCH v7 06/10] ASoC: pxa: Suppress SSPA on ARM64

The SSPA driver currently seems to generate ARM32 assembly, which causes
build errors when building a kernel for an ARM64 ARCH_MMP platform.

Fixes: fa375d42f0e5 ("ASoC: mmp: add sspa support")
Reported-by: kernel test robot <[email protected]>
Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/

This isn't a fix for the existing code, AFAICT the issue here is that
ARCH_MMP is currently only available for arm and presumably something in
the rest of your series makes it available for arm64. This would be a
prerequisite for that patch.

Please don't just insert random fixes tags just because you can.

FWIW it doesn't even seem to be the right reason either. AFACIT the
issue being introduced is that SND_MMP_SOC_SSPA selects SND_ARM which
depends on ARM, but after patch #8 ARCH_MMP itself will no longer
necessarily imply ARM. The fact that selecting SND_ARM with unmet
dependencies also allows SND_ARMAACI to be enabled (which appears to be
the only thing actually containing open-coded Arm asm) is tangential.

NAK, not only is selecting user-visible symbols generally frowned upon,
and ignoring their dependencies even worse, but for a multiplatform
kernel the user may well want this to be a module.

If having the SMMU driver built-in is somehow fundamentally required for
this platform to boot, that would represent much bigger problems.

Thanks,
Robin.

I just looked at it again and it looks like no code in sound/soc/pxa/* or
sound/arm/pxa* depends on AACI in any way. Therefore, I believe that to fix
this correctly, I would have to remove "select SND_ARM" from sound/soc/pxa/
Kconfig and optionally move the PXA2xx code out of sound/arm/ and into sound/
soc/pxa/. Is this correct? If so, I'd also split that fix into a separate
series.

Regards,
Duje

The SoC can boot without SMMU and PDMA, but not GIC, pinctrl or the arch
timer. I see that most other SoCs still select drivers and frameworks they
presumably need for booting, with the exceptions of ARCH_BITMAIN, ARCH_LG1K
and a couple others. Which of these two options should I go for?

Regards,
Duje

Well, you don't really need to select ARM_GIC or ARM_ARCH_TIMER here
either, since those are already selected by ARM64 itself. Keeping
PINCTRL_SINGLE is fair, although you should also select PINCTRL as its
dependency.

As an additional nit, the file seems to be primarily ordered by symbol
name, so it might be nice to slip ARCH_MMC in between ARCH_MESON and
ARCH_MVEBU.

Cheers,
Robin.

There's the pxa-ac97 driver to consider...
