I have three opens with this ACPI/PCI change
1. the baseline change fails on my cross-compilation checks, see below
the result of the attached script (simplification of the one I use to
avoid 0day reports).
2. there are different patterns to express the dependency on PCI e.g.
config MMC_SDHCI_ACPI
tristate "SDHCI support for ACPI enumerated SDHCI controllers"
depends on MMC_SDHCI && ACPI
- select IOSF_MBI if X86
+ select IOSF_MBI if (X86 && PCI)
but
config SND_SST_ATOM_HIFI2_PLATFORM_ACPI
tristate "ACPI HiFi2 (Baytrail, Cherrytrail) Platforms"
default ACPI
- depends on X86 && ACPI
+ depends on X86 && ACPI && PCI
select SND_SST_IPC_ACPI
select SND_SST_ATOM_HIFI2_PLATFORM
select SND_SOC_ACPI_INTEL_MATCH
IOSF is only needed for Baytrail-CR detection, and the code will compile
fine without it, so maybe it'd be a better model if you used the
following diff?
diff --git a/sound/soc/intel/Kconfig b/sound/soc/intel/Kconfig
index 2fd1b61e8331..68af0ea5c96c 100644
--- a/sound/soc/intel/Kconfig

select SND_SST_IPC_ACPI
select SND_SST_ATOM_HIFI2_PLATFORM
select SND_SOC_ACPI_INTEL_MATCH
- select IOSF_MBI
+ select IOSF_MBI if PCI
3. All the Intel machine drivers depend on X86_INTEL_LPSS which depends
on PCI. But for Baytrail/Haswell/Broadwell we have only a dependency on
ACPI, so we expose drivers that can be selected but fail on probe since
there are no machine drivers. I am not sure if we want to be strict and
only expose meaningful configurations, or allow for more compilations
tests and corner cases?
