      ASoC: Fixes for v6.9
      
      This is much larger than is ideal, partly due to your holiday but also
      due to several vendors having come in with relatively large fixes at
      similar times.  It's all driver specific stuff.
      
      The meson fixes from Jerome fix some rare timing issues with blocking
      operations happening in triggers, plus the continuous clock support
      which fixes clocking for some platforms.  The SOF series from Peter
      builds to the fix to avoid spurious resets of ChainDMA which triggered
      errors in cleanup paths with both PulseAudio and PipeWire, and there's
      also some simple new debugfs files from Pierre which make support a lot
      eaiser.

      ALSA: hda/realtek: Fix conflicting PCI SSID 17aa:386f for Lenovo Legion models · 39815cdf
      Takashi Iwai authored
      Unfortunately both Lenovo Legion Pro 7 16ARX8H and Legion 7i 16IAX7
      got the very same PCI SSID while the hardware implementations are
      completely different (the former is with TI TAS2781 codec while the
      latter is with Cirrus CS35L41 codec).  The former model got broken by
      the recent fix for the latter model.
      
      For addressing the regression, check the codec SSID and apply the
      proper quirk for each model now.

      There is a chance of damaging the IC when S4 resume.
      Add safe mode for no stream to disable GPIO3.

      ASoC: meson: tdm fixes · c5782bb5
      Mark Brown authored
      Merge series from Jerome Brunet <jbrunet@baylibre.com>:
      
      This patchset fixes 2 problems on TDM which both find a solution
      by properly implementing the .trigger() callback for the TDM backend.
      
      ATM, enabling the TDM formatters is done by the .prepare() callback
      because handling the formatter is slow due to necessary calls to CCF.
      
      The first problem affects the TDMIN. Because .prepare() is called on DPCM
      backend first, the formatter are started before the FIFOs and this may
      cause a random channel shifts if the TDMIN use multiple lanes with more
      than 2 slots per lanes. Using trigger() allows to set the FE/BE order,
      solving the problem.
      
      There has already been an attempt to fix this 3y ago [1] and reverted [2]
      It triggered a 'sleep in irq' error on the period IRQ. The solution is
      to just use the bottom half of threaded IRQ. This is patch #1. Patch #2
      and #3 remain mostly the same as 3y ago.
      
      For TDMOUT, the problem is on pause. ATM pause only stops the FIFO and
      the TDMOUT just starves. When it does, it will actually repeat the last
      sample continuously. Depending on the platform, if there is no high-pass
      filter on the analog path, this may translate to a constant position of
      the speaker membrane. There is no audible glitch but it may damage the
      speaker coil.
      
      Properly stopping the TDMOUT in pause solves the problem. There is
      behaviour change associated with that fix. Clocks used to be continuous
      on pause because of the problem above. They will now be gated on pause by
      default, as they should. The last change introduce the proper support for
      continuous clocks, if needed.

      ALSA: emu10k1: make E-MU FPGA writes potentially more reliable · 15c7e87a
      Oswald Buddenhagen authored
      We did not delay after the second strobe signal, so another immediately
      following access could potentially corrupt the written value.
      
      This is a purely speculative fix with no supporting evidence, but after
      taking out the spinlocks around the writes, it seems plausible that a
      modern processor could be actually too fast. Also, it's just cleaner to
      be consistent.

      ALSA: emu10k1: fix E-MU dock initialization · e8289fd3
      Oswald Buddenhagen authored
      A side effect of making the dock monitoring interrupt-driven was that
      we'd be very quick to program a freshly connected dock. However, for
      unclear reasons, the dock does not work when we do that - despite the
      FPGA netlist upload going just fine. We work around this by adding a
      delay before programming the dock; for safety, the value is several
      times as much as was determined empirically.
      
      Note that a badly timed dock hot-plug would have triggered the problem
      even before the referenced commit - but now it would happen 100% instead
      of about 3% of the time, thus making it impossible to work around by
      re-plugging.

      ALSA: emu10k1: use mutex for E-MU FPGA access locking · 2d3f4810
      Oswald Buddenhagen authored
      The FPGA access through the GPIO port does not interfere with other
      sound processor register access, so there is no need to subject it to
      emu_lock. And after moving all FPGA access out of the interrupt handler,
      it does not need to be IRQ-safe, either.
      
      What's more, attaching the dock causes a firmware upload, which takes
      several seconds. We really don't want to disable IRQs for this long, and
      even less also have someone else spin with IRQs disabled waiting for us.
      
      Therefore, use a mutex for FPGA access locking.
      
      This makes the code somewhat more noisy, as we need to wrap bigger
      sections into the mutex, as it needs to enclose the spinlocks.
      
      The latter has the "side effect" of fixing dock FPGA programming in a
      corner case: a really badly timed mixer access right between entering
      FPGA programming mode and uploading the netlist would mess up the
      protocol.

      ALSA: emu10k1: move the whole GPIO event handling to the workqueue · f848337c
      Oswald Buddenhagen authored
      The actual event processing was already done by workqueue items. We can
      move the event dispatching there as well, rather than doing it already
      in the interrupt handler callback.
      
      This change has a rather profound "side effect" on the reliability of
      the FPGA programming: once we enter programming mode, we must not issue
      any snd_emu1010_fpga_{read,write}() calls until we're done, as these
      would badly mess up the programming protocol. But exactly that would
      happen when trying to program the dock, as that triggers GPIO interrupts
      as a side effect. This is mitigated by deferring the actual interrupt
      handling, as workqueue items are not re-entrant.
      
      To avoid scheduling the dispatcher on non-events, we now explicitly
      ignore GPIO IRQs triggered by "uninteresting" pins, which happens a lot
      as a side effect of calling snd_emu1010_fpga_{read,write}().

      ALSA: emu10k1: factor out snd_emu1010_load_dock_firmware() · 28deafd0
      Oswald Buddenhagen authored
      Pulled out of the next patch to improve its legibility.
      
      As the function is now available, call it directly from
      snd_emu10k1_emu1010_init(), thus making the MicroDock firmware loading
      synchronous - there isn't really a reason not to. Note that this does
      not affect the AudioDocks of rev1 cards, as these have no independent
      power supplies, and thus come up only a while after the main card is
      initialized.
      
      As a drive-by, adjust the priorities of two messages to better reflect
      their impact.

      ALSA: emu10k1: fix E-MU card dock presence monitoring · 398321d7
      Oswald Buddenhagen authored
      While there are two separate IRQ status bits for dock attach and detach,
      the hardware appears to mix them up more or less randomly, making them
      useless for tracking what actually happened. It is much safer to check
      the dock status separately and proceed based on that, as the old polling
      code did.
      
      Note that the code assumes that only the dock can be hot-plugged - if
      other option card bits changed, the logic would break.
