ALSA: hda - Add dock speaker support for ASUS TX300
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.
ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switches
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.

ALSA: hda - hdmi: Fallback to ALSA allocation when selecting CA
hdmi_channel_allocation() tries to find a HDMI channel allocation that
matches the number channels in the playback stream and contains only
speakers that the HDMI sink has reported as available via EDID. If no
such allocation is found, 0 (stereo audio) is used.
Using CA 0 causes the audio causes the sink to discard everything except
the first two channels (front left and front right).
However, the sink may be capable of receiving more channels than it has
speakers (and then perform downmix or discard the extra channels), in
which case it is preferable to use a CA that contains extra channels
than to use CA 0 which discards all the non-stereo channels.
Additionally, it seems that HBR (HD) passthrough output does not work on
Intel HDMI codecs when CA is set to 0 (possibly the codec zeroes
channels not present in CA). This happens with all receivers that report
a 5.1 speaker mask since a HBR stream is carried on 8 channels to the
codec.
Add a fallback in the CA selection so that the CA channel count at least
matches the stream channel count, even if the stream contains channels
not present in the sink speaker descriptor.
Thanks to GrimGriefer at OpenELEC forums for discovering that changing
the sink speaker mask allowed HBR output.

ASoC: Samsung: Do not queue cyclic buffers multiple times
The legacy S3C-DMA API required every period of a cyclic buffer to be
queued separately. After conversion of Samsung ASoC to Samsung DMA
wrappers somebody made an assumption that the same is needed for DMA
engine API, which is not true.
In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer
multiple times with a shift of one period per iteration, leading to:
a) severe memory waste - up to 13x times more DMA transfer descriptors
are allocated than needed,
b) possible memory corruption, because further cyclic buffers were out
of the original buffers, due to the offset.
This patch fixes this problem by making the legacy S3C-DMA API use the
same semantics as DMA engine (the whole cyclic buffer is enqueued at
once) and modifying users of Samsung DMA wrappers in cyclic mode to
behave appropriately.

BIO_EOPNOTSUPP error detection. The issue was found by Dan Carpenter
and he suggests first version of the fix too.
Being a low-level component, various drivers (e.g. olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe. Therefore the OLPC EC driver must be initialised before other
drivers try to use it. This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").
Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.
Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC. The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

ASoC: Updates for v3.12
- DAPM is now mandatory for CODEC drivers in order to avoid the repeated
regressions in the special cases for non-DAPM CODECs and make it
easier to integrate with other components on boards. All existing
drivers have had some level of DAPM support added.
- A lot of cleanups in DAPM plus support for maintaining controls in a
specific state while a DAPM widget all contributed by Lars-Peter Clausen.
- Core helpers for bitbanged AC'97 reset from Markus Pargmann.
- New drivers and support for Analog Devices ADAU1702 and ADAU1401(a),
Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based
machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung
Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson
Microelectronics WM8997.
- Support for building drivers that can support it cross-platform for
compile test.
IP sends device configuration (see inet_fill_link_af) as an array

exposed to userspace through any current santized header file.

commit fba875591 ("disable TX in be_close()") disabled TX in be_close()

It turns out that the change introduced a potential deadlock
by causing a locking dependency with netlink's cb_mutex. I
can't seem to find a way to resolve this without doing major
changes to the locking, so revert this.

The commit isn't necessarily wrong, but because it recalculates the
random mmap_base every time, it seems to confuse user memory allocators
that expect contiguous mmap allocations even when the mmap address isn't
specified.
In particular, the MATLAB Java runtime seems to be unhappy. See
https://bugzilla.kernel.org/show_bug.cgi?id=60774
So we'll want to apply the random offset only once, and Radu has a patch
for that. Revert this older commit in order to apply the other one.
