I ran into multiple problems during randconfig builds of the
recently changed Kconfig logic for Intel ASoC drivers:
we did quite a bit of testing on this change, looks like we missed a
number of cases. Gah.
- Building without DMADEVICES doesn't work in general
the Intel audio hardware has its own DMA in general, be it based on
DesignWare controlled by audio firmware or HDaudio, not sure if/why this
dependency is needed across the board?
- With that dependency added, we can relax the 'depends
on X86' again and allow compile-testing, except for
SND_SST_ATOM_HIFI2_PLATFORM, which depends on X86
for asm/platform_sst_audio. > - Skylake requires SND_SOC_INTEL_SST_ACPI, so we
have to depend on ACPI in turn
- Haswell needs SND_DMA_SGBUF for snd_sgbuf_aligned_pages()
This one is surprising as well, this was not there before so it either
was not detected or is not needed?
With the new set of dependencies, I no longer get any build
failures.
