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.

A race condition exists in handling firmware boot timeout.
If FW sends FW_READY just after boot timeout has expired in

The prepare() ioctl for BE dai link gets called both
when the stream is started and when it is resumed from
suspend. SOF uses this ioctl to set the hw params
again only if the stream has been suspended.
When the stream is started, the hw_params ioctl gets called
before prepare() and hw_params is set for the BE dai link.
So the prepare call does not need to do anything further.
When the stream resumes after system suspend, SOF requires
that the hw_params be set again for the BE dai. In order
to determine which streams should set the hw params
during prepare(), an internal flag called "hw_params_upon_resume"
is introduced in struct sof_intel_hda_stream. The flag is set
for hda streams when the sof device suspends and is
cleared after hw_params is set.

When using a shared IRQ between IPC interrupt and stream IOC interrupt,
the interrupt handlers need to check the interrupt source before
scheduling their respective IRQ threads. In the case of IPC handler, it
should check if it is an IPC interrupt before waking up the IPC IRQ
thread.
The IPC IRQ thread, once scheduled, does not need to check the IRQ
source again. So, remove the superfluous check in the thread. Remove the
irq_status field from snd_sof_dev struct also as it is no longer needed.

The IPC implementation in SOF requires sending IPCs serially: we should
not send a new IPC command to the firmware before we get an ACK (or time
out) from firmware, and the IRQ processing is complete.
snd_pcm_period_elapsed() can be called in interrupt context before
IRQ_HANDLED is returned. When the PCM is done draining, a STOP
IPC will then be sent, which breaks the expectation that IPCs are
handled serially and leads to IPC timeouts.
This patch adds a workqueue to defer the call to snd_pcm_elapsed() after
the IRQ is handled.

By default, the I2S ports are configured in master mode during
DSP powerup sequences, the FS and BCLK lines will be driven on
startup, even when the topology file explicitly requires the
SSP to be slave.
This may be problematic for external components configured in
master mode who don't expect the Intel SOC/PCH to drive. Fix by
configuring the SSP as slave before the SSP outputs are enabled
to avoid this transient behavior.
When the topology file configures the SSP as clock master, the
initial slave configuration will be overridden.

Currently there are two null checks of pointer dai in function
sof_connect_dai_widget and yet there is no null check of dai
at the end of the function when checking !dai->name. The latter
would be a null pointer deference if dai is null (as picked up
by static analysis), however the function is only ever called
when dai is successfully allocated, so the null checks are
redundant. Clean up the code by removing the null checks.
