[PATCH 0/9] ASoC: Intel: Kconfig fixes

[Pierre-Louis Bossart]

The first patch implements what Linus, Takashi and Mark
requested: a top-level selector defaulting to 'y' to easily filter all
other options and with no impact on code generation. There should be no
functionality change and will avoid breaking audio for people using
make oldnoconfig.

The rest of the patch series does a more in-depth cleanup. It was tested
on Baytrail/Cherrytrail/Skylake platforms with no regressions
observed and no reports of any compilation issues with 0-day or
randconfig.

The 4th patch is really the most important one, there were nested
configs which made no sense to me. I don't know the history which led
to such complicated stuff but simpler is better.

Patches 5..7 are just clean-ups of the machine driver configs,
for some reason there is no consistency in the settings so I tried to
apply common sense and use the same rules. At Andy Shevchenko's suggestion,
I also replaced the broken dependency on X86_INTEL_LPSS by MFD_INTEL_LPSS
for Skylake+ machines. No regressions were identified with this change.

Patches 8 and 9 are new in this series and are just cosmetic changes (comments
and text simplification).

Thanks to Vinod Koul for his contributions and comments.

Changes since RFCv2:
 Moved machine drivers to submenu
 Dropped SND_SOC_INTEL_COMMON since it was not needed
 Added more comments for if/endif
 Simplified text for options (dropped "ASoC Intel driver....")
 Fixed one 0-day warning
 
Changes since initial RFC:
 Removed default n
 Added help text for HASWELL, BAYTRAIL (legacy) and SKYLAKE options 
 Made top level machine driver selection dependent on INTEL_SST_TOPLEVEL.
 Added help text for PCI and HIFI2 platforms
 Replaced X86_INTEL_LPSS by MFD_INTEL_LPSS for Skylake+ devices
 Fixed a couple of indentation issues

[PATCH 1/9] ASoC: Intel: Fix Kconfig with top-level selector

[Pierre-Louis Bossart]

Follow network example suggested by Linus, move Intel definitions
in if/endif block and clarify in help text which options distro
configurations should enable - everything except legacy Baytrail stuff and
NOCODEC (test only)

To avoid user confusion, machine drivers are handled with a submenu made
dependent on this top-level selector.

There should be no functionality change - except that sound capabilities
are restored when using older configs without any user selection.

Note that the SND_SOC_ACPI_INTEL_MATCH config is not filtered out by
the top-level selector since it will also be selected with the upcoming
SOF drivers. Likewise the machine drivers are filtered by a top-level
selector which will allow for selection/reuse of the same machine driver
with existing SST or SOF-based platform drivers.

(simplification with submenu for machine drivers by Vinod Koul)

An item that is selected by others can only select, not depend.
The depends need to be put for the items that select this instead.

Initially the code was

config SND_SOC_ACPI_INTEL_MATCH
         tristate
         select SND_SOC_ACPI if ACPI

I changed it to use depends to make some 0-day reports go away, for some 
reason this option was selected with ARCH=mn10300 and generated 
warnings. I don't quite understand how that happened since X86 and ACPI 
are clear dependencies in the items which select this option...

Vinod also added a similar pattern with

+config SND_SOC_INTEL_SST_TOPLEVEL
+	bool "Intel ASoC SST drivers"
+	default y
+	depends on X86 || COMPILE_TEST
+	select SND_SOC_INTEL_MACH

+menuconfig SND_SOC_INTEL_MACH
+	bool "Intel Machine drivers"
  	depends on SND_SOC_INTEL_SST_TOPLEVEL

Maybe that needs to be removed as well?

Having both depends and select on the top-level is OK.  The only
problem is when an item that is selected by others has another
depends.  For example, a simple-looking case like below is actually
buggy:

config BAR
	tristate
	depends on X

config FOO
	tristate "foo"
	select BAR

Here BAR would be enabled by FOO no matter what X is, even if X=n.
That said, when an item is selected, its own dependency is ignored.

For correcting this, the depends-on-X must be moved to the top-level
who selects the item:

config BAR
	tristate

config FOO
	tristate "foo"
	depends on X
	select BAR

Note that the reverse-select chain works as expected.  The breakage is
only the mixture of select and depends in the selected items.

Looking to somehow established practice (few other Kconfigs in the

[PATCH 2/9] ASoC: Intel: Kconfig: Simplify-clarify ACPI/PCI dependencies

[Pierre-Louis Bossart]

PCI/ACPI selections should not happen in Kconfig for machine drivers,
move to SOC selections.

Add distinction between PCI and ACPI HiFi2 platforms and help text.

There should be no functionality change.

The PCI-based platforms may be removed at some point since Medfield
is not really supported by anyone, and with Edison now defunct support for
Merrifield/Edison is to be determined.

I must admit I don't know why it's different, I just cleaned-up what I 
could. Maybe Liam can comment since I believe he contributed to both 
Haswell and the initial Baytrail driver?

What I'm talking about is to use same pattern, so, in the first case 

	depends on SND_DMA_SGBUF
   	depends on DMADEVICES && ACPI

The question WRT SGBUF is indeed another one to Liam or whoever knows
better.

I would rather start a new line (mind indentation as well) with list of
platforms:

# This option controls ACPI-based probing on
# Haswell/Broadwell/Baytrail legacy and will be set

[PATCH 4/9] ASoC: Intel: Fix nested/unnecessary Kconfig dependencies

[Pierre-Louis Bossart]

This patch fixes a number of issues:
1. IOSF_MBI is only needed for byt-cr detection, which is only supported
on Baytrail/Cherrytrail, move to HiFi2 config

2. SND_SOC_INTEL_SST should not select SND_SOC_INTEL_SST_ACPI, the latter
config is only valid for Haswell/Baytrail legacy but not needed by Skylake

3. SND_SST_IPC_ACPI, used only by the atom/sst driver, should not select
SND_SOC_INTEL_SST, none of the code under common/sst*.c is used

This nesting of configs really makes no sense, it's easier to maintain
if for each platform one can control what is strictly required.

Compiled-tested with each of Haswell, Baytrail legacy, HiFi2, SKL cases
selected independently. 0-day and explicit randconfig tests did not report
additional issues and no functionality loss was observed in Intel tests on
HIFI2 and SKYLAKE platforms

[PATCH 5/9] ASoC: Intel: boards: align Kconfig dependencies for Haswell/Broadwell

[Pierre-Louis Bossart]

Make sure that the same I2C/I2C_DESIGNWARE_PLATFORM are selected.
The latter might actually need to be moved to the SOC side of things,
it really has no place in a machine driver dependency

[PATCH 7/9] ASoC: Intel: boards: align/fix SKL/BXT/KBL Kconfigs

[Pierre-Louis Bossart]

No reason why SND_SOC_INTEL_SST should be set here.
Also make sure same dependencies are used everywhere (only last one has SPI
in addition). Replace X86_INTEL_LPSS by MFD_INTEL_LPSS since the former
makes no sense for Skylake+ devices

"Broadwell Wildcatpoint"

to be in align with Haswell?
