      ALSA: hda: Initialize power_state field properly · 183ab39e
      Takashi Iwai authored
      The recent commit 98081ca6 ("ALSA: hda - Record the current power
      state before suspend/resume calls") made the HD-audio driver to store
      the PM state in power_state field.  This forgot, however, the
      initialization at power up.  Although the codec drivers usually don't
      need to refer to this field in the normal operation, let's initialize
      it properly for consistency.

      ASoC: Fixes for v5.1
      
      A few core fixes along with the driver specific ones, mainly fixing
      small issues that only affect x86 platforms for various reasons (their
      unusual machine enumeration mechanisms mainly, plus a fix for error
      handling in topology).
      
      There's some of the driver fixes that look larger than they are, like
      the hdmi-codec changes which resulted in an indentation change, and most
      of the other large changes are for new drivers like the STM32 changes.

      ALSA: hda/realtek - Add quirk for Tuxedo XC 1509 · 80690a27
      Richard Sailer authored
      This adds a SND_PCI_QUIRK(...) line for the Tuxedo XC 1509.
      
      The Tuxedo XC 1509 and the System76 oryp5 are the same barebone
      notebooks manufactured by Clevo. To name the fixups both use after the
      actual underlying hardware, this patch also changes System76_orpy5
      to clevo_pb51ed in 2 enum symbols and one function name,
      matching the other pci_quirk entries which are also named after the
      device ODM.

      ASoC: Intel: cht_bsw_max98090_ti: Enable codec clock once and keep it enabled · 4bcdec39
      Hans de Goede authored
      Users have been seeing sound stability issues with max98090 codecs since:
      commit 648e9218 ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
      
      At first that commit broke sound for Chromebook Swanky and Clapper models,
      the problem was that the machine-driver has been controlling the wrong
      clock on those models since support for them was added. This was hidden by
      clk-pmc-atom.c keeping the actual clk on unconditionally.
      
      With the machine-driver controlling the proper clock, sound works again
      but we are seeing bug reports describing it as: low volume,
      "sounds like played at 10x speed" and instable.
      
      When these issues are hit the following message is seen in dmesg:
      "max98090 i2c-193C9890:00: PLL unlocked".
      
      Attempts have been made to fix this by inserting a delay between enabling
      the clk and enabling and checking the pll, but this has not helped.
      
      It seems that at least on boards which use pmc_plt_clk_0 as clock,
      if we ever disable the clk, the pll looses its lock and after that we get
      various issues.
      
      This commit fixes this by enabling the clock once at probe time on
      these boards. In essence this restores the old behavior of clk-pmc-atom.c
      always keeping the clk on on these boards.

      ALSA: pcm: Don't suspend stream in unrecoverable PCM state · 113ce081
      Takashi Iwai authored
      Currently PCM core sets each opened stream forcibly to SUSPENDED state
      via snd_pcm_suspend_all() call, and the user-space is responsible for
      re-triggering the resume manually either via snd_pcm_resume() or
      prepare call.  The scheme works fine usually, but there are corner
      cases where the stream can't be resumed by that call: the streams
      still in OPEN state before finishing hw_params.  When they are
      suspended, user-space cannot perform resume or prepare because they
      haven't been set up yet.  The only possible recovery is to re-open the
      device, which isn't nice at all.  Similarly, when a stream is in
      DISCONNECTED state, it makes no sense to change it to SUSPENDED
      state.  Ditto for in SETUP state; which you can re-prepare directly.
      
      So, this patch addresses these issues by filtering the PCM streams to
      be suspended by checking the PCM state.  When a stream is in either
      OPEN, SETUP or DISCONNECTED as well as already SUSPENDED, the suspend
      action is skipped.
      
      To be noted, this problem was originally reported for the PCM runtime
      PM on HD-audio.  And, the runtime PM problem itself was already
      addressed (although not intended) by the code refactoring commits
      3d21ef0b ("ALSA: pcm: Suspend streams globally via device type PM
      ops") and 17bc4815 ("ALSA: pci: Remove superfluous
      snd_pcm_suspend*() calls").  These commits eliminated the
      snd_pcm_suspend*() calls from the runtime PM suspend callback code
      path, hence the racy OPEN state won't appear while runtime PM.
      (FWIW, the race window is between snd_pcm_open_substream() and the
      first power up in azx_pcm_open().)
      
      Although the runtime PM issue was already "fixed", the same problem is
      still present for the system PM, hence this patch is still needed.
      And for stable trees, this patch alone should suffice for fixing the
      runtime PM problem, too.

      In the observed situation, the problem is seen because the codec driver
      failed to probe due to a hardware problem.

      The problem is similar to the problem solved with commit 2fc995a8
      ("ASoC: intel: Fix crash at suspend/resume without card registration"),
      but codec registration fails at a later point. At that time, the pointer
      checked with the above mentioned commit is already set, but it is not
      cleared if the device is subsequently removed. Adding a remove function
      to clear the pointer fixes the problem.
