ASoC: Fixes for v5.0

Quite a big batch of fixes here.  There's a couple of things going on,
the main one is that we found some issues with not deferring probe when
we should, causing us to skip some driver initialization.  The fixes for
this then in turn exposed some issues with how we were searching for
components which had previously gone unnoticed due to the original
issue.

There's also been the normal driver specific stuff and there's been what
looks like several batches of automated scanning for issues which have
generated quite a large set of smaller fixes for potential crashes and
missed error handling.

ASoC: intel: skl: Fix display power regression

2019-01-14T18:06:29+00:00

Since the refactoring of HD-audio display power management, the
display power status is managed per domain.  Meanwhile the ASoC
hdac_hdmi driver still keeps and relies (incorrectly) on the
refcounting together with ASoC skl driver, and this leads to the
display state always on.

This patch is an attempt to address the regression by simplifying the
PM code of ASoC skl and hdac_hdmi drivers.  Basically, since the
refactoring, we don't have to manage the display power at HD-audio
controller suspend / resume but only at HD-audio HDMI codec suspend /
resume.  So the patch drops the superfluous snd_hdac_display_power()
calls in skl driver.

Meanwhile, in hdac_hdmi side, we rewrite the PM call just to re-use
the runtime PM callbacks like other drivers do.  Now the logic is
simple: turn off at suspend and turn on at resume.

The patch also fixes the possibly missing display-power off at skl
driver removal as well as some error paths at probe.

ASoC: Intel: Boards: move the codec PLL configuration to _init

2019-01-09T19:26:47+00:00

move the codec PLL to rt5682_codec_init, because codec only need to config the clock source/PLL once.
As the result, remove the platform_clock_controls since no need to control clock anymore.

ASoC: atom: fix a missing check of snd_pcm_lib_malloc_pages

2019-01-07T18:10:03+00:00

snd_pcm_lib_malloc_pages() may fail, so let's check its status and
return its error code upstream.

ASoC: Intel: atom: Make PCI dependency explicit

2019-01-03T16:33:22+00:00

After 'commit 5d32a66541c4 ("PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set")' dependencies on CONFIG_PCI that previously were
satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly. This code relies on IOSF_MBI and IOSF_MBI depends
on PCI. For this reason, add a direct dependency on CONFIG_PCI to the
IOSF_MBI driver.

ASoC: Intel: Haswell/Broadwell: fix setting for .dynamic field

2019-01-03T16:32:50+00:00

For some reason this field was set to zero when all other drivers use
.dynamic = 1 for front-ends. This change was tested on Dell XPS13 and
has no impact with the existing legacy driver. The SOF driver also works
with this change which enables it to override the fixed topology.

ALSA: hda - Revert DSP detection on legacy HD-audio driver

2019-01-01T19:43:01+00:00

This essentially reverts the commits
  c337104b1a16 ("ALSA: HD-Audio: SKL+: abort probe if DSP is present
  and Skylake driver selected")
and
  d82b51c855a2 ("ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+
  driver selection")
for the path of legacy HD-audio controller (snd-hda-intel).

The automatic DSP detection and skip of binding with the legacy driver
caused regressions on several machines like Dell XPS13.  They give the
PCI class 0x40380 indicating the availability of DSP while they don't
work with ASoC SKL driver (yet).

As the support of ASoC driver for such devices isn't available, it's
better to revert the whole DSP-detection-and-skip behavior of the
legacy driver, so that we can get the old good driver working on such
devices.

The pci_binding option for ASoC SKL driver is still kept so that it
can work without blacklisting.

ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection

2018-12-19T17:07:23+00:00

For HDaudio and Skylake drivers, add module parameter "pci_binding"

When pci_binding == 0 (AUTO), the PCI class/subclass info is used to
select drivers based on the presence of the DSP.

pci_binding == 1 (LEGACY) forces the use of the HDAudio legacy driver,
even if the DSP is present.

pci_binding == 2 (ASOC) forces the use of the ASOC driver. The
information on the DSP presence is bypassed.

The value for the module parameter needs to be identical for both
drivers. This parameter is intended as a back-up solution if the
automatic detection fails or when the DSP usage fails. Such cases
should be reported on the alsa-devel mailing list for analysis.

ALSA: HD-Audio: SKL+: abort probe if DSP is present and Skylake driver selected

2018-12-19T17:07:21+00:00

Now that the SST/Skylake driver supports per platform selectors, we
can add logic to automatically select the right driver.

If the Skylake driver is selected for a specific platform, and the DSP
is detected at run-time based on the PCI class/subclass/prog-if
information, the legacy HDaudio driver aborts the probe. This will
result in a single driver probing and remove the need for modprobe
blacklists.

Follow-up patches will add a module parameter to bypass the logic if
this automatic detection fails, or if the Skylake driver is unable to
actually support the platform (firmware authentication, missing
topology file, hardware issue, etc).

The same mechanism will be used to conflicts generated by the same PCI
ID being registered by both legacy HDAuudio and SOF drivers for Intel
platforms. In other words SOF will not require changes to the HDaudio
legacy.

Merge tag 'asoc-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2018-12-18T13:59:56+00:00

ASoC: Updates for v4.21

Not much work on the core this time around but we've seen quite a bit of
driver work, including on the generic DT drivers.  There's also a large
part of the diff from a merge of the DaVinci and OMAP directories, along
with some active development there:

 - Preparatory work from Morimoto-san for merging the audio-graph and
   audio-graph-scu cards.
 - A merge of the TI OMAP and DaVinci directories, the OMAP product line
   has been merged into the DaVinci product line so there is now a lot
   of IP sharing which meant that the split directories just got in the
   way.  This has pulled in a few architecture changes as well.
 - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers.
