[PATCH 1/3] ALSA: hda - Remove dependency on bus->pci in hda_beep.c

[PATCH 1/3] ALSA: hda - Remove dependency on bus->pci in hda_beep.c

[Takashi Iwai]

The default parent device can be obtained directly via card object, so
we don't need to rely on pci->dev.parent.  Since there is no access to
pci_dev, we can reduce the inclusion of linux/pci.h, too.

[PATCH 2/3] ALSA: hda/realtek - Allow NULL bus->pci

[Takashi Iwai]

Realtek codec driver contains some codes referring to the PCI
subdevice IDs, but most of them are optional, typically for checking
the codec name variants.  Add NULL checks appropriately so that it can
work without PCI assignment.

I forgot the cover page: these tree patches are trivial cleanups of
hda-codec drivers (not the controller) to work without PCI device
assignment. The idea was triggered by Dylan's question.

Thanks Takashi,

I tested this series on a Haswell and IvyBridge system. Looks good to
me as well.

Thanks.  Any chance to work on / submit other changes for Tegra
HD-audio support?

As already mentioned, I think a cleaner way would be to write
hda_platform.c instead of hacking hda_intel.c with ifdefs.
Some code in hda_intel.c (e.g. bus ops and PCM callbacks) can be moved
out, either as a new helper module or just merging into snd-hda-codec
helper module, so that they can be used by both hda_intel.c and
hda_platform.c.

Ideally, we may rename hda_intel.c with hda_pci.c, but I'm afraid this
would bring too many regressions for module options.

That's the plan, hopefully I'll be able to find time to throw together
an RFC by the end of the week.

That sounds like a good idea.  There aren't a lot of differences,
mostly isolated to init and suspend/resume.  That should be easy to
put in hda_platform.

Since there was no patch appearing yet, I merged my latest development
branch to for-next branch, which includes lots of changes in
hda_intel.c and hda_codec.c.  If any, please rebase your patches to
it.

Thanks for the heads up.  I've got a series that is almost ready, I'm
still trying to tease part of the build out from under CONFIG_PCI in
the hda makefile.  I'll try to button that up and get a the whole lot
rebased on top of the for-next branch.

I don't think we have a dependency on CONFIG_PCI in Makefile.  Kconfig
has a dependency, but it can be easily reduced by a patch like below.

Of course, it'd be better to move the whole hda directory out of pci,

Sounds good.  I was looking at re-using some of the config options
(HDMI codec and power save) for the platform driver as well.  Maybe
something like the following.  SND_HDA would build the helper module
and hda-codec that are used by both hda_intel and a platform driver.

I can add that to the end of the series or it can move it whenever is
convenient, not sure how many pending patch sets it would disrupt.

Thanks!

I think we can simply allow building all HD-audio codec drivers when
CONFIG_SND_HDA is set.  They are basically independent from the
controller type.  There are also other selectable items like hwdep
support.  The diff in sound/pci/hda would be like below.

Thanks I'll work off of that.  It will need a change
