ASoC: qcom: Actually clear DMA interrupt register for HDMI
In commit
da0363f7bfd3 ("ASoC: qcom: Fix for DMA interrupt clear reg
overwriting") we changed regmap_write() to regmap_update_bits() so that
we can avoid overwriting bits that we didn't intend to modify.
Unfortunately this change breaks the case where a register is writable
but not readable, which is exactly how the HDMI irq clear register is
designed (grep around LPASS_HDMITX_APP_IRQCLEAR_REG to see how it's
write only). That's because regmap_update_bits() tries to read the
register from the hardware and if it isn't readable it looks in the
regmap cache to see what was written there last time to compare against
what we want to write there. Eventually, we're unable to modify this
register at all because the bits that we're trying to set are already
set in the cache.
This is doubly bad for the irq clear register because you have to write
the bit to clear an interrupt. Given the irq is level triggered, we see
an interrupt storm upon plugging in an HDMI cable and starting audio
playback. The irq storm is so great that performance degrades
significantly, leading to CPU soft lockups.
Fix it by using regmap_write_bits() so that we really do write the bits
in the clear register that we want to. This brings the number of irqs
handled by lpass_dma_interrupt_handler() down from ~150k/sec to ~10/sec.

With this patch in the tree, Chromebooks running the affected hardware
no longer boot. Bisect points to this patch, and reverting it fixes
the problem.
An analysis of the code with this patch applied shows:
ret = init_clks(pdev, clk);
if (ret)
return ERR_PTR(ret);
...
for (j = 0; j < MAX_CLKS && data->clk_id[j]; j++) {
struct clk *c = clk[data->clk_id[j]];

return ERR_CAST(c);
}
scpd->clk[j] = c;
}
Not all clocks in the clk_names array have to be present. Only the clocks
in the data->clk_id array are actually needed. The code already checks if
the required clocks are available and bails out if not. The assumption that
all clocks have to be present is wrong, and commit
9de2b9286a6d ("ASoC:

ASoC: soc-pcm: Move debugfs removal out of spinlock
The recent fix for DPCM locking also covered the loop in
dpcm_be_disconnect() with the FE stream lock. This caused an
unexpected side effect, thought: calling debugfs_remove_recursive() in
the spinlock may lead to lockdep splats as the code there assumes the
SOFTIRQ-safe context.
For avoiding the problem, this patch changes the disconnection
procedure to two phases: at first, the matching entries are removed
from the linked list, then the resources are freed outside the lock.

ASoC: soc-pcm: Fix DPCM lockdep warning due to nested stream locks
The recent change for DPCM locking caused spurious lockdep warnings.
Actually the warnings are false-positive, as those are triggered due
to the nested stream locks for FE and BE. Since both locks belong to
the same lock class, lockdep sees it as if a deadlock.
For fixing this, we need to take PCM stream locks for BE with the
nested lock primitives. Since currently snd_pcm_stream_lock*() helper
assumes only the top-level single locking, a new helper function
snd_pcm_stream_lock_irqsave_nested() is defined for a single-depth
nested lock, which is now used in the BE DAI trigger that is always
performed inside a FE stream lock.

ASoC: xilinx: xlnx_formatter_pcm: Make buffer bytes multiple of period bytes
This patch is based on one in the Xilinx kernel tree, "ASoc: xlnx: Make
buffer bytes multiple of period bytes" by Devarsh Thakkar. The same
issue exists in the mainline version of the driver. The original
patch description is as follows:
"The Xilinx Audio Formatter IP has a constraint on period
bytes to be multiple of 64. This leads to driver changing
the period size to suitable frames such that period bytes
are multiple of 64.
Now since period bytes and period size are updated but not
the buffer bytes, this may make the buffer bytes unaligned
and not multiple of period bytes.
When this happens we hear popping noise as while DMA is being
done the buffer bytes are not enough to complete DMA access
for last period of frame within the application buffer boundary.
To avoid this, align buffer bytes too as multiple of 64, and
set another constraint to always enforce number of periods as
integer. Now since, there is already a rule in alsa core
to enforce Buffer size = Number of Periods * Period Size
this automatically aligns buffer bytes as multiple of period
bytes."

It makes no sense to cache the test/user key registers, since they
require values written at specific times, mark them volatile. It is
probably best if they can't be accessed from user-space either, so
mark them precious as well.
The interrupt force, edge, polarity and debounce are all settings
applied to the IRQ rather than status bits and as such should not be
volatile.
The OTP trim values will require re-application in the event of a
cache sync and as such should not be volatile. The OTPID however
should be volatile.
The DSP scratch registers are used to read back an error/debug code
from the DSP on shutdown, as such these should be marked volatile.
Finally, add some missing defaults, add TST_FS_MON0, and allow the

ASoC: Intel/SOF: use set_stream() instead of set_tdm_slots() for HDAudio
Overloading the tx_mask with a linear value is asking for trouble and
only works because the codec_dai hw_params() is called before the
cpu_dai hw_params().
Move to the more generic set_stream() API to pass the hdac_stream
information.

ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire
The HDAudio ASoC support relies on the set_tdm_slots() helper to store
the HDaudio stream tag in the tx_mask. This only works because of the
pre-existing order in soc-pcm.c, where the hw_params() is handled for
codec_dais *before* cpu_dais. When the order is reversed, the
stream_tag is used as a mask in the codec fixup functions:
/* fixup params based on TDM slot masks */
if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK &&
codec_dai->tx_mask)
soc_pcm_codec_params_fixup(&codec_params,
codec_dai->tx_mask);
As a result of this confusion, the codec_params_fixup() ends-up
generating bad channel masks, depending on what stream_tag was
allocated.
We could add a flag to state that the tx_mask is really not a mask,
but it would be quite ugly to persist in overloading concepts.
Instead, this patch suggests a more generic get/set 'stream' API based
on the existing model for SoundWire. We can expand the concept to
store 'stream' opaque information that is specific to different DAI
types. In the case of HDAudio DAIs, we only need to store a stream tag
as an unsigned char pointer. The TDM rx_ and tx_masks should really
only be used to store masks.
Rename get_sdw_stream/set_sdw_stream callbacks and helpers as
get_stream/set_stream. No functionality change beyond the rename.

soundwire: intel: improve suspend flows
This patch provides both a simplification of the suspend flows and a
better balanced operation during suspend/resume transition, as part of
the transition of Sound Open Firmware (SOF) to dynamic pipelines: the
DSP resources are only enabled when required instead of enabled on
startup.
The exiting code relies on a convoluted way of dealing with suspend
signals. Since there is no .suspend DAI callback, we used the
component .suspend and marked all the component DAI dmas as
'suspended'. The information was used in the .prepare stage to
differentiate resume operations from xrun handling, and only
reinitialize SHIM registers and DMA in the former case.
While this solution has been working reliably for about 2 years, there
is a much better solution consisting in trapping the TRIGGER_SUSPEND
in the .trigger DAI ops. The DMA is still marked in the same way for
the .prepare op to run, but in addition the callbacks sent to DSP
firmware are now balanced.
Normal operation:
hw_params -> intel_params_stream
hw_free -> intel_free_stream
suspend -> intel_free_stream
prepare -> intel_params_stream
This balanced operation was not required with existing SOF firmware
relying on static pipelines instantiated at every boot. With the
on-going transition to dynamic pipelines, it's however a requirement
to keep the use count for the DAI widget balanced across all
transitions.
The component suspend is not removed but instead modified to deal with
a corner case: when a substream is PAUSED, the ALSA core does not
throw the TRIGGER_SUSPEND. This is problematic since the refcount for
all pipelines and widgets is not balanced, leading to issues on
resume. The trigger callback keeps track of the 'paused' state with a
new flag, which is tested during the component suspend called later to
release the remaining DSP resources. These resources will be
re-enabled in the .prepare step.
The IPC used in the TRIGGER_SUSPEND to release DSP resources is not a
problem since the BE dailink is already marked as non-atomic.

ASoC/soundwire: intel: simplify callbacks for params/hw_free
We don't really need to pass a substream to the callback, we only need
the direction. No functionality change, only simplification to enable
improve suspend with paused streams.
