Takashi Iwai 54f7190b23 ALSA: hda - Fix Oops at reloading beep devices
The recent change for supporting dynamic beep device allocation caused
a problem resulting in Oops at reloading the driver.  Also, it ignores
the error from input device registration.

This patch fixes the wrong check in snd_hda_detach_beep_device(), and
returns an error when the input device registration fails properly.

Wu Fengguang ef18beded8 ALSA: hda - HDMI sticky stream tag support
When we run the following commands in turn (with
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),

	speaker-test -Dhw:0,3 -c2 -twav  # HDMI
	speaker-test -Dhw:0,0 -c2 -twav  # Analog

The second command will produce sound in the analog lineout _as well as_
HDMI sink. The root cause is, device 0 "reuses" the same stream tag that
was used by device 3, and the "intelhdmi - sticky stream id" patch leaves
the HDMI codec in a functional state. So the HDMI codec happily accepts
the audio samples which reuse its stream tag.

The proposed solution is to remember the last device each azx_dev was
assigned to, and prefer to
1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used
2) or assign a never-used azx_dev for HDMI

With this patch and the above two speaker-test commands,
HDMI codec will use stream tag 8 and Analog codec will use 5.

The stream tag used by HDMI codec won't be reused by others, as long
as we don't run out of the 4 playback azx_dev's. The legacy Analog
codec will continue to use stream tag 5 because its device id is 0
(this is a bit tricky).

Hector Martin f5de24b06a ALSA: HDA: add powersaving hook for Realtek
The current Realtek code makes no specific provision for turning stuff
off. The codec chip is placed into low-power mode generically, but this
doesn't turn off any external hardware connected to it, in particular
external amplifiers.

This patch creates a hook function that is called by the codec
suspend/resume functions. It ought to disable any external hardware in a
device-specific way. I've implemented a generic ALC889 function that
sets the EAPD pin properly, and used it for the Acer Aspire 8930G which
can benefit from this feature.

On my laptop, this results in ~0.5W extra savings.

André Goddard Rosa e7d2860b69 tree-wide: convert open calls to remove spaces to skip_spaces() lib function
Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.

It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
   text    data     bss     dec     hex filename
  64688     584     592   65864   10148 (TOTALS-BEFORE)
  64641     584     592   65817   10119 (TOTALS-AFTER)

Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".

Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below,
and found occurrences of this pattern on 3 more files:

Andres Salomon 3c55494670 ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimization
Previously, OLPC support for the mic extensions was only enabled in the
ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set.  This was
because the old geode GPIO code was written in a manner that assumed
CONFIG_MGEODE_LX.  With the new cs553x-gpio driver, this is no longer the
case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead
include a requirement on GPIOLIB.

We use the generic GPIO API rather than the cs553x-specific API.

Steve Soule f74890277a ALSA: ac97_codec - increase timeout for analog sections to 5 second
I have a Soundblaster 16PCI. For many years, alsa has had a bug where
not all of the card's controls are detected (many alsa versions,
many kernel versions). In particular, Master Playback Volume is
usually not detected, and so I get no sound or extremely faint sound.
The problem has always been inconsistent: sometimes all of the controls
are detected correctly, and sometimes a partial set is detected. It works
correctly about 10% of the time.

Finally, I got around to tracking down the problem. When the driver
fails, it prints the kernel message "AC'97 0 analog subsections not
ready". This message is generated from the function snd_ac97_mixer()
in ac97_codec.c. The message indicates that the card failed to come
back after reset within the time limit. The time limit is
120 milliseconds.

I tried increasing the time limit to 1 second, and found that this
made the driver work about 70% of the time. I tried increasing it
to 5 seconds, and it now seems to work 100% of the time.

I expect that this change would be completely harmless for
existing cards that work, and would only introduce additional
delay for cards that do not work.

Wu Fengguang b14224bb74 ALSA: intelhdmi - add channel mapping for typical configurations
IbexPeak is the first Intel HDMI audio codec to support channel mapping.

Currently the outstanding problem is, the HDMI channel order do not
agree with that of ALSA.  This patch presents workaround for some
typical use cases. It gives priority to the typical ALSA surround
configurations, and defines channel mapping for them.

We may need better kernel+userspace interactive channel mapping scheme.
For example, in current scheme if user plays with the surround50 device,
the kernel is unaware of this and will still select the surround41
channel allocation and channel mapping..

HDA036 spec states:
  DP (Display Port) indicates whether the Pin Complex Widget supports
  connection to a Display Port sink.  Supported if set to 1. Note that
  it is possible for the pin widget to support more than one digital
  display connection type, e.g. HDMI and DP bit are both set to 1.

Also export the DP pin cap in procfs.

Vitaliy Kulikov c357aab02e ALSA: hda - Fix LED GPIO setup for HP laptops with IDT codecs
This patch fixes an error in processing of the HP BIOS configuration to enable
GPIO based mute LED indicator control. That error causes driver to enable
such control on all HP systems with the 92HD75 IDT codecs and results in
unnecessary toggling of the GPIO on mute control manipulation.

It also adds support of the future HP BIOS configuration extension for the
named control. New configuration string has a format HP_Mute_LED_P_G
where P can be 0 or 1 and defines mute LED GPIO control state (low/high)
that corresponds to the NOT muted state of the master volume
and G is the index of the GPIO to use (0..9)

Lastly, it adds more systems to the support of the audio implementation
as found on HP B-series systems
