The conversion here is really trivial: just a bunch of title
markups and very few puntual changes is enough to make it to
be parsed by Sphinx and generate a nice html.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.

you might feel like a deja vu to receive a bulk of changes at rc5,
and it happens again; we've got a collection of fixes for ASoC.
Most of fixes are targeted for the newly merged SOF (Sound Open
Firmware) stuff and the relevant fixes for Intel platforms.
Other than that, there are a few regression fixes for the recent
ASoC core changes and HD-audio quirk, as well as a couple of
FireWire fixes and for other ASoC codecs.

As part of the suspend flow, a context save IPC message is
sent to the firmware before powering down the DSP. If errors
are met, the suspend flow is aborted with current code.
Change the behaviour such that if firmware returns -EBUSY or
-EAGAIN, return the error codes to PM core as before. The device
is left in active state in this case.
If other errors are reported, print a warning but do not block the
suspend flow. As per interface specification, no valid error can be
returned in this scenario. If the hardware has hit a fatal error and
is not able to respond successfully, best recovery method is to
proceed with suspend and power off the DSP.

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.

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.

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.
