      ALSA: hda - unmute pin amplifier in infoframe setup for Haswell · 58f7d28d
      Mengdong Lin authored 
      When Gfx driver reconnects a port and transcoder, the pin amplifier will
be muted. To enable sound, the pin amp need to be unmuted.

This patch
- moves pin amp unmuting from stream preparing to hdmi_setup_audio_infoframe().
  So if port:transcoder reconnection happens during stream playback, the ELDV
  unsol event can stil trigger pin's amp unmuting when re-setting up audio
  info frame.

- remove reading pin amp status before unmuting for speed-up, since pin amp
  should always be unmuted.

- rename haswell_verify_pin_D0() to haswell_verify_D0(), since the convertor
  power state is also fixed here.

This patch is mostly based on suggestion of David Henningsson.

whether a display audio codec is Haswell, to avoid explicitly checking Haswell

      ALSA: hda - Add dock speaker support for ASUS TX300 · 7bba2157
      Takashi Iwai authored 
      ASUS TX300 has a built-in speaker in the tablet part and in the dock
part, and the tablet speaker is supposed to be unused while the
machine is docked.  The current HD-audio driver, however, doesn't
support the dock speaker, partly because BIOS doesn't set up the pin
for the corresponding output.

But, not only the missing pin config, also the missing unsol event
handling is another issue.  Otherwise the automatic switching via
dock/undock won't work.

Through debugging sessions, we found out that the dock speaker pin is
NID 0x1b, and it generates an unsol event at docking/undocking, the
docking state can be inquired via the normal pin detection verb.
Also, it's turned out that GPIO 2 is needed as an amp.  So, all
materials are ready to cook.

This patch provides the basic dock speaker support with TX300:
- The dock speaker is turned on/off via "Dock Speaker" mixer mute.
- The dock speaker is automatically muted when docked.  This is
  independently from the mixer mute switch, just like the headphone
  auto-mute function.

The implementation is a bit tricky.  Since we want to handle it as a
secondary speaker, we set it up a pin as a speaker with a jack
detection.  Then, the fixup function registers the own unsol callback
for this pin because the standard automute can't handle the thing like
a "speaker jack".  In the own automute hook, we apply the mute of the
tablet speaker in addition by checking the dock state.

Also, the speaker control names are slightly shuffled because the
generic parser doesn't give good names but blindly assumes a bass
speaker as a secondary speaker.

      ASoC: kirkwood: change the compatible string of the kirkwood-i2s driver · d098b2f0
      Thomas Petazzoni authored 
      The compatible string of the kirkwood-i2s driver was chosen as
"marvell,mvebu-audio". Using such a compatible string is not a good
idea, since "mvebu" is the name of a large family of SOCs, in which
new, unknown SOCs will be coming in the future. It is therefore
impossible to know what will be evolutions of this hardware block in
the next generations of the SOCs. For this reason, the recommandation
for compatible strings of on-SOCs devices has always been to use the
name of the oldest SOC that has the hardware block. New SOCs that have
an exactly compatible hardware block can reference it using the same
compatible string. See [1], [2] and [3] for various cases were this
suggestion was made, including from Rob Herring, a Device Tree binding
maintainer.

As an example, there are already small differences between current
generations:

 * On Kirkwood, only one interrupt is used for audio.
 * On Dove, two interrupts are used, one for audio data and one for
   error reporting.

In the near future, I'll be adding audio support to Armada 370, which
allows has the same hardware block (but maybe with minor variants).

Therefore, this patch changes the driver to accept
"marvell,kirkwood-audio" and "marvell,dove-audio" as compatible
strings instead of the too-generic "marvell,mvebu-audio". The reason
for the two different compatible strings is the difference in the
number of interrupts used by the two SOCs for audio.

This Device Tree binding has never been part of a Linux kernel stable
release so far, so it can be changed now without breaking backward
compatibility.

In order to fix this, add a check for 'of_id' so that

      ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switches · b054087d
      Takashi Iwai authored 
      When the transcoder:port mapping on Haswell HDMI/DP audio is changed
during the stream playback, the sound gets lost.  Typically this
problem is seen when the user switches the graphics mode from eDP+DP
to DP-only configuration, where CRTC 1 is used for DP in the former
while CRTC 0 is used for the latter.

The graphics controller notifies the change via the normal ELD update
procedure, so we get the intrinsic event.  For enabling the sound
again, the HDMI audio driver needs to reset the pin and set up the
audio infoframe again.

This patch achieves it by:
- keep the current status of channels and info frame setup in per_pin
  struct,
- check the reconnection in the intrinsic event handler,
- reset the pin and the re-invoke hdmi_setup_audio_infoframe()
  accordingly.

The hdmi_setup_audio_infoframe() function has been changed, too, so
that it can be invoked without passing the substream instance.

The patch is mostly based on the work by Mengdong Lin.

      Pull networking fixes from David Miller:

 1) There was a simplification in the ipv6 ndisc packet sending
    attempted here, which avoided using memory accounting on the
    per-netns ndisc socket for sending NDISC packets.  It did fix some
    important issues, but it causes regressions so it gets reverted here
    too.  Specifically, the problem with this change is that the IPV6
    output path really depends upon there being a valid skb->sk
    attached.

    The reason we want to do this change in some form when we figure out
    how to do it right, is that if a device goes down the ndisc_sk
    socket send queue will fill up and block NDISC packets that we want
    to send to other devices too.  That's really bad behavior.

    Hopefully Thomas can come up with a better version of this change.

 2) Fix a severe TCP performance regression by reverting a change made
    to dev_pick_tx() quite some time ago.  From Eric Dumazet.

 3) TIPC returns wrongly signed error codes, fix from Erik Hugne.

 4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
    skb->sk too early.  Fix from Li Hongjun.

 5) RAW ipv4 sockets can use the wrong routing key during lookup, from
    Chris Clark.

 6) Similar to #1 revert an older change that tried to use plain
    alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner
    mark which needs to see the skb->sk for such frames.  From Phil
    Oester.

 7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz,
    specifically in the handling of virtual functions.

 8) IPSEC path error propagations to sockets is not done properly when
    we have v4 in v6, and v6 in v4 type rules.  Fix from Hannes Frederic
    Sowa.

 9) Fix missing channel context release in mac80211, from Johannes Berg.

10) Fix network namespace handing wrt.  SCM_RIGHTS, from Andy
    Lutomirski.

11) Fix usage of bogus NAPI weight in jme, netxen, and ps3_gelic
    drivers.  From Michal Schmidt.

12) Hopefully a complete and correct fix for the genetlink dump locking
    and module reference counting.  From Pravin B Shelar.

13) sk_busy_loop() must do a cpu_relax(), from Eliezer Tamir.

14) Fix handling of timestamp offset when restoring a snapshotted TCP
    socket.  From Andrew Vagin.
