The A83t and compatibles controllers don't have any reception capabilities
on some instances of the controllers, even though it was never documented
as such in the binding before.
Therefore, on those controllers, we don't have the option to set an RX DMA
channel.
This was already done in the DTSI, but the binding itself was never
updated. Let's add a special case in the schemas.

The Allwinner SoCs feature an I2S controller across multiple SoC
generations.
However, earlier generations were a bit simpler than the subsequent ones,
and for example would always have RX and TX capabilities, and no reset

Current trace implementation gets out of sync when sof device
is put to suspend. The debugfs file handle is kept open, but
firmware will reset its state. After resume, debugfs client's
read offset will not be synchronized to firmware and this may
result in traces read in incorrect order and/or stale data being
read after resume.
Add logic to signal end-of-file to read() when firmware tracing
has ended, and all trace data has been read. This allows debugfs
client to capture all trace data, and reopen the trace file to
ensure proper synchronization with firmware after reopening
the node.

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
sizeof(*w) + sizeof(struct sof_ipc_window_elem) * w->num_windows
with:
struct_size(w, window, w->num_windows)
Notice that variable size is unnecessary, hence it is removed.

Currently on all supported platforms the IPC IRQ thread first signals
the sender when an IPC response is received from the DSP, then unmasks
the IPC interrupt. Those actions are performed without holding any
locks, so the thread can be interrupted between them. IPC timeouts
have been observed in such scenarios: if the sender is woken up and it
proceeds with sending the next message without unmasking the IPC
interrupt, it can miss the next response. This patch takes a spin-lock
to prevent the IRQ thread from being preempted at that point. It also
makes sure, that the next IPC transmission by the host cannot take
place before the IRQ thread has finished updating all the required IPC
registers.

sof_pcm_hw_params() can only be called once to setup the FW hw_params.
So after calling sof_pcm_hw_params(), hw_params_upon_resume flag must
be cleared to avoid multiple invoking sof_pcm_hw_params() by prepare.
For example, after resume, there is an xrun happened, prepare() will
be called. As the hw_params_upon_resume flag is not cleared,
sof_pcm_hw_params() will be called and this will cause IPC timeout.
This patch fixes such issues.

In some configurations, it's a requirement to split the probe in two,
with a second part handled in a workqueue (e.g. for HDMI support
which depends on the DRM modules).
SOF already handles these configurations but the error flow is
incorrect. When an error occurs in the workqueue, the probe has
technically already completed. If we release the resources on errors,
this generates kernel oops/use-after-free when the resources are
released a second time on module removal.

snd_sof_remove() disables the DSP and unmaps the DSP BAR.
Removing topology after disabling the DSP results in a
kernel panic while unloading the pipeline widget. This is
because pipeline widget unload attempts to power down
the core it is scheduled on by accessing the DSP registers.
So, the suggested fix here is to unregister the machine driver
first to remove the topology and then disable the DSP
to avoid the situation described above.
Note that the kernel panic only happens in cases where the
HDaudio link is not managed by the hdac library,
e.g. no codec or when HDMI is not supported.
When the hdac library is used, snd_sof_remove() calls
snd_hdac_ext_bus_device_remove() to remove the codec which
unregisters the component driver thereby also removing the
topology before the DSP is disabled.

But, after this commit, if user uses unbind/bind to Component factor

Revert commit 069d037aea98 ("ASoC: simple-card: Fix configuration of

was caused by an incorrectly formatted device-tree node describing the
soundcard.
The following is incorrect because the simple-audio-card
'bitclock-master' and 'frame-master' properties should not reference the
actual codec phandle ...
sound {
compatible = "simple-audio-card";
...
=> simple-audio-card,bitclock-master = <&codec>;
=> simple-audio-card,frame-master = <&codec>;
...
simple-audio-card,cpu {
sound-dai = <&xxx>;
};
simple-audio-card,codec {
=> sound-dai = <&codec>;
};
};
Rather, these properties should reference the phandle to the
'simple-audio-card,codec' property as shown below ...
sound {
compatible = "simple-audio-card";
...
=> simple-audio-card,bitclock-master = <&codec>;
=> simple-audio-card,frame-master = <&codec>;
...

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with
memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = krealloc(instance, sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, use the new
struct_size() helper:
instance = krealloc(instance, struct_size(instance, entry, count), GFP_KERNEL);

This is an implementation of a machine driver needed for Conexant

the other Intel machine drivers.

top of the original work.
Tested with ASUS E200HA laptop.

Initial commit of the Conexant CX2072X CODEC driver. Some features are
not present.
The CX2072X is a ultra low power stereo audio codec supports I2S/TDM
host interface with EQ, DRC features in playback mode.
Featues of CX2072X codec:
* Two 24 bits DACs and DACs.
* Stereo Headphone AMP.
* 2.8W per channel class-D output.
* Integrated seven bands per channel EQ and DRC.
* Fully integrated headset support with detect/switch.
* Stereo digital microphone for array applications.
* S/PDIF output.
* Bi-directional GPIOs.
* Support analog and digital PC Beeep.
* One headset button support.
* Supports a wide variety of host interfaces.
-wide variety of I2S and similar bit-stream formats
with word lengths of up to 24 bits.
-TDM stream supports up to 4 channels.
* AEC loopback support.
Further fixes by tiwai:
* Rebase to 5.2+
* Missing DAPM entry definitions
* Missing power hooks
* Fix uninitialized variable warning
* Rewrite jack detection stuff to use set_jack callback
* Plumbing jack detection code for Intel ASoC
* Move clk management into runtime PM
* Drop incorrect regcache usages
* Drop untested stuff: OF table, EQ/DRC handling
* Lots of code cleanups and minor refactoring
The OF code was dropped due to the lack of testability.
It should be easy to re-add once if someone can test it.
v1->v2: No change
v2->v3: Move register tables to appropriate place
Remove some confusing codes
Set snd_ctl_boolean_* helpers directly
Fix EQ put callback
Rename to "DAC1 Switch" from "DAC1 Mute Switch"
Drop superfluous regmap calls at shutdown
Avoid regmap_register_patch()
Add missing register definitions
Fix register access on big-endian machine
Remove regcache messes
v3->v4: Fix the wrong endianess conversion in reg write
Minor code cleanups
v4->v5: Move clk management to runtime PM
Sparse warning fixes
Some more code simplification
Drop tricky regcache fiddling
Apply mutex locks around possible racy sequences
Move exported jack detection stuff into set_jack callback
v5->v6: Drop buggy&untested EQ and DRC codes
Lots of code reduction/cleanup
Add more comments about platform-specific stuff

When configuring a codec to be both bit-clock and frame-master, it was
found that the codec was always configured as bit-clock and frame-slave.
Looking at the simple_dai_link_of() function there appears to be two
problems with the configuration of the DAI format, which are ...
1. The function asoc_simple_parse_daifmt() is called before the function
asoc_simple_parse_codec() and this means that the device-tree node
for the codec has not been parsed yet, which is needed by the
function asoc_simple_parse_daifmt() to determine who is the codec.
2. The phandle passed to asoc_simple_parse_daifmt() is the phandle to
the 'codec' node and not the phandle of the actual codec defined by
the 'sound-dai' property under the 'codec' node.
Fix the above by moving the call to asoc_simple_parse_daifmt() after the
the call to asoc_simple_parse_codec() and pass the phandle for the codec
to asoc_simple_parse_daifmt().
