Merge series from Peng Fan <peng.fan@nxp.com>:
This patchset is a pick up of patch 1,2 from [1]. And I also collect
Linus's R-b for patch 2. After this patchset, there is only one user of
of_gpio.h left in sound driver(pxa2xx-ac97).
of_gpio.h is deprecated, update the driver to use GPIO descriptors.
Patch 1 is to drop legacy platform data which in-tree no users are using it
Patch 2 is to convert to GPIO descriptors
Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
ASoC has 2 functions to set bias level.
(A) snd_soc_dapm_force_bias_level()
(B) snd_soc_dapm_set_bias_level()
(A) sets dapm->bias_level, but (B) is not.
I think we should set it on both (A) and (B).
I think it is miss or bug, but Samsung is the only vendor that feels a
problem about this.
I think this patch (= [1/5]) is correct approach, but some non-samsung
vendor might get affect from this patch-set, so I added [RFC] on this
patch-set.
Furthermore, (B) cares both Card and Component, (A) cares Component only.
I guess it is the reason why it is called as "force" bias_level function.
(A) is used from each drivers, (B) is used from soc-dapm only.
I'm not 100% sure though, except special cases, each driver should use (B),
I guess ?

The sysclk frequency can be calculated from sample rate multiply ratio.
When sysclk_freq is not configured, but sysclk_ratio is configured, then
calculate sysclk frequency according to sysclk_ratio.

(B) static int snd_soc_dapm_set_bias_level(...)

if (dapm != &card->dapm)
(A) ret = snd_soc_dapm_force_bias_level(...);
...
ret = snd_soc_card_set_bias_level_post(...);
...
}
dapm->bias_level will be set if (A) was called, but might not be set
if (B) was called, even though it calles set_bias_level() function.
We should set dapm->bias_level if we calls
snd_soc_dapm_set_bias_level() (B), too.

It is currently possible to configure a kernel with all Intel SoC

Add an optional dependency on SND_SOC_SOF_INTEL_COMMON, to ensure that whenever
the SOF support is in a loadable module, none of the board code can be built-in.
This may be be a little heavy-handed, but I also don't see a reason why one would
want the boards to be built-in but not the SoC, so it shouldn't actually cause
any usability problems.

Convert the HDMI codec drivers to use the new hda_codec_ops probe.
The Intel and Nvidia-MCP HDMI drivers needed slightly more changes to
deal with the unified callbacks among all models.
Also another non-trivial change is Intel driver's set_power_state
callback. An additional NULL check of codec->spec is needed there
since the set_power_state() may be called before the probe gets called
(e.g. in ASoC hda codec hda_codec_probe()).

Until now, we use "patch_ops" embedded in hda_codec object for
defining the callbacks that are used in various places to manage
HD-audio codec. But from the device driver POV, this should have been
rather the driver ops, instead of the callbacks in the codec object.
This patch defines the driver ops for HD-audio codec driver as the
replacement. We reuse the same struct hda_codec_ops, and this is put
as hda_codec_driver.ops. When the driver->ops callbacks are defined,
they are called primarily instead of codec->patch_ops callbacks.
With converting to the driver ops, there is no need to pass the ugly
patch_ops handling in hda_device_id tables. That is, driver_data
field of hda_device_id becomes really optional and it can be used for
passing the codec-specific data (e.g. specifying a model).
The codec entries after the conversion should be with HDA_CODEC_ID()
and co, instead of the former HDA_CODEC_ENTRY().
Once after converting all codec drivers to use driver ops, we can get
rid of codec patch_ops.

In the past, we unified HD-audio HDMI codec driver once with a slight
hope that more vendors will follow the standard, but in reality, the
driver received more and more vendor-specific code. In order to make
the messy code a bit more understandable, this patch splits the HDMI
codec driver into multiple drivers again.
Namely, the vendor-specific code for Intel, AMD and Nvidia are moved
into the own drivers, while we split the common HDMI code to two
drivers, the generic HDMI driver and the simple HDMI driver.
So, now we have:
- The generic HDMI driver (snd-hda-codec-hdmi):
providing the common helpers, also supports Glenfly HDMI codecs and
some other codecs that don't need vendor-specific stuff
- The simple HDMI driver (snd-hda-codec-simplehdmi):
devices with no dynamic PCM assignment and with fixed channels,
mostly used by some other drivers, but this driver alone suffices
for VIA HDMI codec support, too
- Intel HDMI driver (snd-hda-codec-intelhdmi):
bound with i915 / Xe DRM, based on the generic HDMI driver
- AMD/ATI HDMI driver (snd-hda-codec-atihdmi):
optionally bound with radeon / amdgpu DRM, based on the generic HDMI
driver
- Nvidia HDMI driver (snd-hda-codec-nvhdmi);
optionally bound with nouveau DRM, based on the generic HDMI driver
- Legacy Nvidia HDMI driver (snd-hda-codec-nvhdmi-mcp):
for 2ch or 8ch outputs, based on the simple HDMI driver
- Nvidia Tegra HDMI driver (snd-hda-codec-tegrahdmi):
based on the generic HDMI driver
Along with the driver split, the enable_silent_stream module option is
moved to snd-hda-codec-intelhdmi, too, as it's an Intel-specific
feature.
Most of the changes here are just to split and move the code to
different files, as well as to rename/expose the functions that are
commonly used by drivers.
The silent stream handling code is slightly modified for putting the
stuff into Intel driver; now a new callback "silent_stream" is defined
in hdmi_ops, and it's called in silent_stream_enable() and *_disable()
functions. The runtime-PM handling in silent_stream_enable() was
cleaned up, and rather taking the runtime PM refcount in the
silent_stream() callback appropriately, instead.
Other than that, there should be no functional changes.

The snd-hda-codec-realtek driver supports many different codec models
and accumulated lots of quirks. Now let's split it to multiple
modules per probe function, i.e. for ALC260, ALC262, ALC269, etc.
The common code and quirks are provided by the common library module,
snd-hda-codec-realtek-lib now. One drawback of this action is that
many symbols have to be exported. But they are limited with
SND_HDA_CODEC_REALTEK namespace, at least.
This patch tries to be idiomatic and doesn't try to rewrite the
existing code. We can move the codec model-specific code into each
codec driver later.
The HD-audio sub-codec component binding is currently specific to
ALC269, hence the management is moved into alc269.c.
After that, alc_free() became identical with snd_hda_gen_free(), and
it's replaced as a macro just to call snd_hda_gen_free().

Now move the all remaining codec drivers from sound/pci/hda to
sound/hda/codecs subdirectory. Some drivers are put under the further
vendor subdirectory, and the vendor helper code (*_helper.c) are put
under helpers subdirectory. Also the sub-codec drivers are moved under
a different subdirectory, sound/hda/codecs/sub-codecs, for
distinguishing from the main HD-audio codec drivers.
The prefix patch_ and hda_ as well as the suffix _helper are dropped
from file names as they are mostly superfluous.
No functional changes but just file path shuffling.

are independent from PCI bus, hence it makes more sense to put under
sound/hda.
The hda_ prefix is dropped from most of files at moving, as it's
more or less superfluous.

CONFIG_SND_HDA_PREALLOC_SIZE is used only by controller.c in
sound/hda/common, hence it depends on CONFIG_SND_HDA.
Move the definition to the right place inside SND_HDA if/endif block
in sound/hda/common/Kconfig.

The snd-hda-codec module contains the most of common code used by both
HD-audio controller and codec drivers, and it's basically independent
from PCI. Let's move the code to sound/hda/common directory as a part
of code reorganization.
The hda_ prefix is dropped from the most of file names as it's rather
superfluous.

This is a part of HD-audio code restructuring.
Simply move the current code of sound/hda/* into the subdirectory
sound/hda/core, so that more stuff can be moved into sound/hda cleanly
later.
Most of file names with hdac_ and hdac_ext_ prefix are renamed without
the prefix, since they can be identified well in the directory name
and superfluous.

The get_wcaps() and co are used not only by HD-audio core but also
other driver code, hence it'd be better to put into the common header
instead of local.h.
OTOH, there are macros of the same name like get_wcaps() that are
still used in sound/pci/hda/* locally, and those conflict with each
other. So we need to rename get_wcaps() (to be moved from hda-core)
with the proper snd_hdac prefix for avoiding name conflicts, and
define in the common hdaudio.h.

Replace the remaining strcpy() and sprintf() usages in the ALSA core
code with the safer versions.
The first strcpy() points actually to card->id, hence just use
strscpy() with card->id instead.
The append of suffix string is slightly rewritten so that we can use
scnprintf() and strscpy().
Only for safety, no actual behavior change.

Replace strcpy() and sprintf() usages in the USB audio drivers with
the safer versions (strscpy() and scnprintf()) with the proper max
size evaluation. Only for safety, no actual behavior change.

The probe code uses sprintf() and strcat() without caring about the
string buffer size. Replace with safer code.
Only a cosmetic safety matter, no functional changes intended.

snd_ac97_get_name() blindly assumes that the name buffer is large
enough, but we should be more careful. Pass the max buffer length and
allow trimming to the size.
Only a cosmetic safety matter, no functional changes intended.

Use a safer function strscpy() instead of strcpy() for copying to
arrays.
Only idiomatic code replacement, and no functional changes.
