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?
Probably my mistake. I'll try again without the dependency and see what problems I run into then and what the correct fix is.
I immediately ran into this Kconfig warning, so this is clearly for the two users of SND_SOC_INTEL_SST_FIRMWARE:
warning: (SATA_DWC_OLD_DMA && SERIAL_8250_LPSS && SND_SOC_INTEL_SST_FIRMWARE) selects DW_DMAC_CORE which has unmet direct dependencies (DMADEVICES)
The BYT legacy drivers used DMAengine (dw) to load the firmware and hence the dependency. The Skylake and other drivers do not need that, so we should move this from toplevel to the BYT driver only.
I'm testing with this fixup now:

this is required as we need this DMA driver. It might not have issues on compile but functionality would be broken.
