To be compliant with i915 display driver requirements, i915 power-up
must be done before any HDA communication takes place, including
parsing the bus capabilities. Otherwise the initial codec probe
may fail.
Move i915 initialization earlier in the SOF HDA sequence. This
sequence is now aligned with the snd-hda-intel driver where the
display_power() call is before snd_hdac_bus_parse_capabilities()
and rest of the capability parsing.
Also remove unnecessary ifdef around hda_codec_i915_init(). There's
a dummy implementation provided if CONFIG_SND_SOC_SOF_HDA is not

When HDA controller is resumed from suspend, i915 HDMI/DP
codec requires that following order of actions is kept:
- i915 display power up and configuration of link params
- hda link reset and setup
Current SOF HDA code delegates display codec power control
to the codec driver. This works most of the time, but in
runtime PM sequences, the above constraint may be violated.
On platforms where BIOS values for HDA link parameters do
not match hardware reset defaults, this may lead to errors
in HDA verb transactions after resume.
Fix the issue by explicitly powering the display codec
in the HDA controller resume/suspend calls, thus ensuring
correct ordering. Special handling is needed for the D0i3
flow, where display power must be turned off even though
DSP is left powered.
Now that we have more invocations of the display power helper
functions, the conditional checks surrounding each call have
been moved inside hda_codec_i915_display_power(). The two
special cases of display powering at initial probe are handled
separately. The intent is to avoid powering the display whenever
no display codecs are used.
Note that early powering of display was removed in
commit 687ae9e287 ("ASoC: intel: skl: Fix display power regression").
This change was also copied to the SOF driver. No failures
have resulted as hardware default values for link parameters
have worked out of the box. However with recent i915 driver
changes like done in commit 87c1694533 ("drm/i915: save
AUD_FREQ_CNTRL state at audio domain suspend"), this does not
hold anymore and errors are hit.

Furthermore, a clock issue with 24-bit support has been identified with

Multiple Intel ASoC machine drivers repeat the same pattern in their
.late_probe() methods: they first check whether the common HDMI codec
driver is used, if not, they proceed by linking the legacy HDMI
driver to each HDMI port. While doing that they use some
inconsistent code:
1. after the loop they check, whether the list contained at least one
element and if not, they return an error. However, the earlier
code to use the common HDMI driver uses the first element of the
same list without checking. To fix this we move the check to the
top of the function.
2. some of those .late_probe() implementations execute code, only
needed for the common HDMI driver, before checking, whether the
driver is used. Move the code to after the check.
3. Some of those functions also perform a redundant initialisation of
the "err" variable.
This patch fixes those issues.

The initial intent of releasing resources in the .remove does not work
well with HDaudio codecs. If the probe_continue() fails in a work
queue, e.g. due to missing firmware or authentication issues, we don't
release any resources, and as a result the kernel oopses during
suspend operations.
The suggested fix is to release all resources during errors in
probe_continue(), and use fw_state to track resource allocation
state, so that .remove does not attempt to release the same
hardware resources twice. PM operations are also modified so that
no action is done if DSP resources have been freed due to
an error at probe.

Change HDA probe behaviour slightly so that i915 power is not
turned off if i915 audio codecs are found in the initial probe done
by SOF Intel driver, and power is kept on until HDA codec driver
probe runs.
This will reduce number of mode sets on platforms with low
minimum CDCLK (like GLK) and brings the SOF probe sequence closer
to legacy HDA driver in terms of i915 audio codec power management.

The current interface to control i915 display power is misleading.
The hda_codec_i915_get() and hda_codec_i915_put() names suggest
a refcounting based interface. This is confusing as no refcounting
is done and the underlying HDAC library interface does not support
refcounts eithers.
Clarify the code by replacing the functions with a single
hda_codec_i915_display_power() that is aligned with
snd_hdac_display_power().

Commit 08df0d9a00 ("ASoC: max98090: revert "ASoC: max98090: fix lockdep
warning"") provided a good rationale for removing separate lock for the
SHDN register access. However it restored the lockdep warning during the
system boot. To silence the lockdep warning, mark the mutex taken in the
max98090_shdn_save() function with the lockdep class dedicated for the
runtime DAPM operations: SND_SOC_DAPM_CLASS_RUNTIME. This finally fixes
the following lockdep warning observed on Exynos4412-based Odroid U3
board:

All rtd->dai_link callback functions are controlled by soc_rtd_xxxx(),
and checking rtd->dai_link->ops.
We don't need to have null_snd_soc_ops anymore.
This patch removes it.
