ASoC: hdac_hdmi: use devm_kzalloc for all structures
Loading/unloading modules exposes issues with memory allocation, which
is a mix of devm_kzalloc and manual kzalloc. Move to devm_k routines
everywhere to simplify all this.

687ae9e287 ASoC: intel: skl: Fix display power regression
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.

ed49e83919 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.

029d92c289 ALSA: hda: Refactor display power management
The current HD-audio code manages the DRM audio power via too complex
redirections, and this seems even still unbalanced in a corner case as
Intel DRM CI has been intermittently reporting.  This patch is a big
surgery for addressing the complexity and the possible unbalance.

Basically the patch changes the display PM in the following ways:

- Both HD-audio controller and codec drivers call a single helper,
  snd_hdac_display_power().  (Formerly, the display power control from
  a codec was done indirectly via link_power bus ops.)

- snd_hdac_display_power() receives the codec address index.  For
  turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER.

- snd_hdac_display_power() doesn't manage refcounts any longer, but
  keeps the power status in bitmap.  If any of controller or codecs is
  turned on, the function updates the DRM power state via get_power()
  or put_power().

Also this refactor allows us more cleanup:

- The link_power bus ops is dropped, so there is no longer indirect
  management, as mentioned in the above.

- hdac_device link_power_control flag is moved to hda_codec
  display_power_control flag, as it's only for HDA legacy.

ASoC: Intel: Power down links before turning off display audio power
On certain platforms, Display HDMI HDA codec was not going to sleep state
after the use when links are powered down after turning off the display
power. As per the HW recommendation, links are powered down before turning
off the display power to ensure that the codec goes to sleep state.

This patch was updated from an earlier version submitted upstream [1]
which conflicted with the changes merged for HDaudio codec support
with the Intel DSP.

a57942bfdd ALSA: hda: Make audio component support more generic
This is the final step for more generic support of DRM audio
component.  The generic audio component code is now moved to its own
file, and the symbols are renamed from snd_hac_i915_* to
snd_hdac_acomp_*, respectively.  The generic code is enabled via the
new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is
kept as the super-class.

Along with the split, three new callbacks are added to audio_ops:
pin2port is for providing the conversion between the pin number and
the widget id, and master_bind/master_unbin are called at binding /
unbinding the master component, respectively.  All these are optional,
but used in i915 implementation and also other later implementations.

A note about the new snd_hdac_acomp_init() function: there is a slight
difference between this and the old snd_hdac_i915_init().  The latter
(still) synchronizes with the master component binding, i.e. it
assures that the relevant DRM component gets bound when it returns, or
gives a negative error.  Meanwhile the new function doesn't
synchronize but just leaves as is.  It's the responsibility by the
caller's side to synchronize, or the caller may accept the
asynchronous binding on the fly.

82887c0beb ALSA: hda/i915: Associate audio component with devres
The HD-audio i915 binding code contains a single pointer, hdac_acomp,
for allowing the access to audio component from the master bind/unbind
callbacks.  This was needed because the callbacks pass only the device
pointer and we can't guarantee the object type assigned to the drvdata
(which is free for each controller driver implementation).
And this implementation will be a problem if we support multiple
components for different DRM drivers, not only i915.

As a solution, allocate the audio component object via devres and
associate it with the given device, so that the component callbacks
can refer to it via devres_find().

The removal of the object is still done half-manually via
devres_destroy() to make the code consistent (although it may work
without the explicit call).

Also, the snd_hda_i915_register_notifier() had the reference to
hdac_acomp as well.  In this patch, the corresponding code is removed
by passing hdac_bus object to the function, too.

ae891abe7c drm/i915: Split audio component to a generic type
For allowing other drivers to use the DRM audio component, rename the
i915_audio_component_* with drm_audio_component_*, and split the
generic part into drm_audio_component.h.  The i915 specific stuff
remains in struct i915_audio_component, which contains
drm_audio_component as the base.

The license of drm_audio_component.h is kept to MIT as same as the the
original i915_component.h.

This is a preliminary change for further development, and no
functional changes by this patch itself, merely code-split and
renames.

v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915
        argument in drm_audio_component.h

a180ba45b1 ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.
Done using Coccinelle:

static struct snd_soc_codec_driver s@p={...};

66d6bbc6c0 ASoC: hdac_hdmi: Update sig_bits based on converter capability
When creating the codec dai, use sig_bits to update the max bps based
on the codec capability. So both the link DMA and codec format will be
calculated based on DAI sig_bits.

So update the sig_bits with converter capability and use the sig_bits
for HDA format calculation.

e0e5d3e5a5 ASoC: hdac_hdmi: Add support for multiple ports to a PCM
Since we have the MST feature enabled and Pin-Port mux for user to
select the converter routing, multiple port mapping to same converter
needs to be supported.

To support multiple port mapped to same converter following changes are
done for this:.
o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

1b46ebd136 ASoc: hdac_hdmi: Configure pin verbs for MST
To enable stream on a specific port of a MST capable pin, the port
needs to be selected before we configure the pin widget verb.

When port is selected, all the pin widget verb controlling the sink
device operation will be directed to selected port. So add port
selection before configuring the pin widget verb.

a9ce96bcd9 ASoC: hdac_hdmi: Handle MST pin jack detection at boot/resume
The ELD notification can be received asynchronously from the graphics
side and this may happen just at the moment the sound driver is
initializing and notification will be missed. Similarly at system
resume, the notification is ignored as the  ELD and connection states
are updated in anyway at the end of the resume.
So check the jack status in boot/resume by querying the port presence
based on pin caps and report the jack status.
