Current simple card drivers are parsing widgets on each own driver
(only simple-card at this point, but will be supported on all drivers)
Encapsulation is one of simple card util's purpose.
Let's add asoc_simple_card_of_parse_widgets for it.

Drivers can implement 'struct snd_pcm_ops.ioctl' to handle some requests
from ALSA PCM core. These requests are internal purpose in kernel land.
Usually common set of operations are used for it.
SNDRV_PCM_IOCTL1_INFO is one of the requests. According to code comment,
it has been obsoleted in the old days.
We can see old releases in ftp.alsa-project.org. The command was firstly
introduced in v0.5.0 release as SND_PCM_IOCTL1_INFO, to allow drivers to
fill data of 'struct snd_pcm_channel_info' type. In v0.9.0 release,
this was obsoleted by the other commands for ioctl(2) such as
SNDRV_PCM_IOCTL_CHANNEL_INFO.
This commit removes the long-abandoned command, bye.

Currently OSS sequencer emulation is tied with ALSA sequencer core,
both are built in the same level; i.e. when CONFIG_SND_SEQUENCER=y,
the OSS sequencer emulation is also always built-in, even though the
functionality can be built as an individual module.
This patch changes the rule and allows users to build snd-seq-oss
module while others are built-in. Essentially, it's just a few simple
changes in Kconfig and Makefile. Some driver codes like opl3 need to
convert from the simple ifdef to IS_ENABLED(). But that's all.
You might wonder how about the dependency: right, it can be messy, but
it still works. Since we rewrote the sequencer binding with the
standard bus, the driver can be bound at any time on demand. So, the
synthesizer driver module can be loaded individually from the OSS
emulation core before/after it.

Now all materials are ready, let's allow the direct in-kernel
read/write, i.e. a kernel-space buffer is passed for read or write,
instead of the normal user-space buffer. This feature is used by OSS
layer and UAC1 driver, for example.
The __snd_pcm_lib_xfer() takes in_kernel argument that indicates the
in-kernel buffer copy. When this flag is set, another transfer code
is used. It's either via copy_kernel PCM ops or the normal memcpy(),
depending on the driver setup.
As external API, snd_pcm_kernel_read(), *_write() and other variants
are provided.
That's all. This support is really simple because of the code
refactoring until now.

Both __snd_pcm_lib_read() and __snd_pcm_write() functions have almost
the same code to loop over samples. For simplification, this patch
unifies both as the single helper, __snd_pcm_lib_xfer().
Other than that, there should be no functional change by this patch.

Now that all users of old copy and silence ops have been converted to

For supporting the explicit in-kernel copy of PCM buffer data, and
also for further code refactoring, three new PCM ops, copy_user,
copy_kernel and fill_silence, are introduced. The old copy and
silence ops will be deprecated and removed later once when all callers
are converted.
The copy_kernel ops is the new one, and it's supposed to transfer the
PCM data from the given kernel buffer to the hardware ring-buffer (or
vice-versa depending on the stream direction), while the copy_user ops
is equivalent with the former copy ops, to transfer the data from the
user-space buffer.
The major difference of the new copy_* and fill_silence ops from the
previous ops is that the new ops take bytes instead of frames for size
and position arguments. It has two merits: first, it allows the
callback implementation often simpler (just call directly memcpy() &
co), and second, it may unify the implementations of both interleaved
and non-interleaved cases, as we'll see in the later patch.
As of this stage, copy_kernel ops isn't referred yet, but only
copy_user is used.

Several files are used to construct PCM core module, a.k.a snd-pcm.
Although available APIs are described in 'include/sound/pcm.h', some of
them are not exported as symbols in kernel space. Such APIs are just for
module local usage.
This commit adds module local header file and move some function prototypes
into it so that scopes of them are controlled properly and developers
get no confusion from unavailable symbols.

The indirect-PCM helper codes have an implicit assumption that the
appl_ptr always increases. But the PCM core may deal with the
decrement of appl_ptr via rewind ioctls, and it may screw up the
buffer pointer management.
This patch adds the negative appl_ptr diff in transfer functions and
let returning an error instead of always accepting the appl_ptr
updates. The callers are usually PCM ack callbacks, and they pass the
error to the upper layer accordingly.

To solve this issue, this patch adds new snd_soc_get_dai_id() and

In below case, we can handle Sound port (= port@2) as ID = 0
if .of_xlate_dai_id has its support.
hdmi {
port@0 { /* VIDEO */ };
port@1 { /* VIDEO */ };

There are many codecs with the capability of jack detection. Usually,
we create a jack on machine driver but there is no common function for
machine driver to deliver the jack pointer to codec driver.
snd_soc_codec_set_jack can be used for delivering the jack pointer to
codec driver and enable the jack detection function. To make it work,
codec driver need to define a callback function to receive the jack
pointer and do all necessary procedure for enabling jack detection.

The macros _snd_hdac_chip_read() and *_write() expand to different
types (b,w,l) per their argument. They were thought to be used only
internally for other snd_hdac_chip_*() macros, but in some situations
we need to call these directly, and they are way too ugly.
Instead of saving a few lines, we just write these macros explicitly
with the types, so that they can be used in a saner way.

commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...")
tried to replace aux_comp_list to component_dev_list,
but it failed because of binding timing. Thus, Sylwester fixuped it by
commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary...").
One of main purpose of commit 1a653aa44725 ("ASoC: core: replace...")
was remove replaceable list (= list_aux) from snd_soc_component by using
new "auxiliary" flags (but it failed).
Because of this background, current code has reborned card_aux_list
(= same as original list_aux), and almost pointless "auxiliary" flags.
Let's remove pointless "auxiliary" flags by this patch
This means, it is same as revert both
commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...") and
commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary...").

To make those patches build cleanly prepare the scene by adding

These changes all make sense standalone: they add a header for
a data type that a particular .c or .h file is using.
