Sound updates for 3.7-rc1 

This contains pretty many small commits covering fairly large range of
 files in sound/ directory.  Partly because of additional API support
 and partly because of constantly developed ASoC and ARM stuff.
 
 Some highlights:
 
 - Introduced the helper function and documentation for exposing the
   channel map via control API, as discussed in Plumbers; most of PCI
   drivers are covered, will follow more drivers later
 
 - Most of drivers have been replaced with the new PM callbacks (if
   the bus is supported)
 
 - HD-audio controller got the support of runtime PM and the support of
   D3 clock-stop.  Also changing the power_save option in sysfs kicks
   off immediately to enable / disable the power-save mode.
 
 - Another significant code change in HD-audio is the rewrite of
   firmware loading code.  Other than that, most of changes in HD-audio
   are continued cleanups and standardization for the generic auto
   parser and bug fixes (HBR, device-specific fixups), in addition to
   the support of channel-map API.
 
 - Addition of ASoC bindings for the compressed API, used by the
   mid-x86 drivers.
 
 - Lots of cleanups and API refreshes for ASoC codec drivers and
   DaVinci.
 
 - Conversion of OMAP to dmaengine.
 
 - New machine driver for Wolfson Microelectronics Bells.
 
 - New CODEC driver for Wolfson Microelectronics WM0010.
 
 - Enhancements to the ux500 and wm2000 drivers
 
 - A new driver for DA9055 and the support for regulator bypass mode.

ALSA PCM channel-mapping API
============================
Takashi Iwai <tiwai@suse.de>
GENERAL
-------
The channel mapping API allows user to query the possible channel maps
and the current channel map, also optionally to modify the channel map
of the current stream.
A channel map is an array of position for each PCM channel.
Typically, a stereo PCM stream has a channel map of
{ front_left, front_right }
while a 4.0 surround PCM stream has a channel map of
{ front left, front right, rear left, rear right }.
The problem, so far, was that we had no standard channel map
explicitly, and applications had no way to know which channel
corresponds to which (speaker) position. Thus, applications applied
wrong channels for 5.1 outputs, and you hear suddenly strange sound
from rear. Or, some devices secretly assume that center/LFE is the
third/fourth channels while others that C/LFE as 5th/6th channels.
Also, some devices such as HDMI are configurable for different speaker
positions even with the same number of total channels. However, there
was no way to specify this because of lack of channel map
specification. These are the main motivations for the new channel
mapping API.
DESIGN
------
Actually, "the channel mapping API" doesn't introduce anything new in
the kernel/user-space ABI perspective. It uses only the existing
control element features.
As a ground design, each PCM substream may contain a control element
providing the channel mapping information and configuration. This
element is specified by:
iface = SNDRV_CTL_ELEM_IFACE_PCM
name = "Playback Channel Map" or "Capture Channel Map"
device = the same device number for the assigned PCM substream
index = the same index number for the assigned PCM substream
Note the name is different depending on the PCM substream direction.
Each control element provides at least the TLV read operation and the
read operation. Optionally, the write operation can be provided to
allow user to change the channel map dynamically.
* TLV
The TLV operation gives the list of available channel
maps. A list item of a channel map is usually a TLV of
type data-bytes ch0 ch1 ch2...
where type is the TLV type value, the second argument is the total
bytes (not the numbers) of channel values, and the rest are the
position value for each channel.
As a TLV type, either SNDRV_CTL_TLVT_CHMAP_FIXED,
SNDRV_CTL_TLV_CHMAP_VAR or SNDRV_CTL_TLVT_CHMAP_PAIRED can be used.
The _FIXED type is for a channel map with the fixed channel position
while the latter two are for flexible channel positions. _VAR type is
for a channel map where all channels are freely swappable and _PAIRED
type is where pair-wise channels are swappable. For example, when you
have {FL/FR/RL/RR} channel map, _PAIRED type would allow you to swap
only {RL/RR/FL/FR} while _VAR type would allow even swapping FL and
RR.
These new TLV types are defined in sound/tlv.h.
The available channel position values are defined in sound/asound.h,
here is a cut:
/* channel positions */
enum {
SNDRV_CHMAP_UNKNOWN = 0,
SNDRV_CHMAP_NA, /* N/A, silent */
SNDRV_CHMAP_MONO, /* mono stream */
/* this follows the alsa-lib mixer channel value + 3 */
SNDRV_CHMAP_FL, /* front left */
SNDRV_CHMAP_FR, /* front right */
SNDRV_CHMAP_RL, /* rear left */
SNDRV_CHMAP_RR, /* rear right */
SNDRV_CHMAP_FC, /* front center */
SNDRV_CHMAP_LFE, /* LFE */
SNDRV_CHMAP_SL, /* side left */
SNDRV_CHMAP_SR, /* side right */
SNDRV_CHMAP_RC, /* rear center */
/* new definitions */
SNDRV_CHMAP_FLC, /* front left center */
SNDRV_CHMAP_FRC, /* front right center */
SNDRV_CHMAP_RLC, /* rear left center */
SNDRV_CHMAP_RRC, /* rear right center */
SNDRV_CHMAP_FLW, /* front left wide */
SNDRV_CHMAP_FRW, /* front right wide */
SNDRV_CHMAP_FLH, /* front left high */
SNDRV_CHMAP_FCH, /* front center high */
SNDRV_CHMAP_FRH, /* front right high */
SNDRV_CHMAP_TC, /* top center */
SNDRV_CHMAP_TFL, /* top front left */
SNDRV_CHMAP_TFR, /* top front right */
SNDRV_CHMAP_TFC, /* top front center */
SNDRV_CHMAP_TRL, /* top rear left */
SNDRV_CHMAP_TRR, /* top rear right */
SNDRV_CHMAP_TRC, /* top rear center */
SNDRV_CHMAP_LAST = SNDRV_CHMAP_TRC,
};
When a PCM stream can provide more than one channel map, you can
provide multiple channel maps in a TLV container type. The TLV data
to be returned will contain such as:
SNDRV_CTL_TLVT_CONTAINER 96
SNDRV_CTL_TLVT_CHMAP_FIXED 4 SNDRV_CHMAP_FC
SNDRV_CTL_TLVT_CHMAP_FIXED 8 SNDRV_CHMAP_FL SNDRV_CHMAP_FR
SNDRV_CTL_TLVT_CHMAP_FIXED 16 NDRV_CHMAP_FL SNDRV_CHMAP_FR \
SNDRV_CHMAP_RL SNDRV_CHMAP_RR
The channel position is provided in LSB 16bits. The upper bits are
used for bit flags.
#define SNDRV_CHMAP_POSITION_MASK 0xffff
#define SNDRV_CHMAP_PHASE_INVERSE (0x01 << 16)
#define SNDRV_CHMAP_DRIVER_SPEC (0x02 << 16)
SNDRV_CHMAP_PHASE_INVERSE indicates the channel is phase inverted,
(thus summing left and right channels would result in almost silence).
Some digital mic devices have this.
When SNDRV_CHMAP_DRIVER_SPEC is set, all the channel position values
don't follow the standard definition above but driver-specific.
* READ OPERATION
The control read operation is for providing the current channel map of
the given stream. The control element returns an integer array
containing the position of each channel.
When this is performed before the number of the channel is specified
(i.e. hw_params is set), it should return all channels set to
UNKNOWN.
* WRITE OPERATION
The control write operation is optional, and only for devices that can
change the channel configuration on the fly, such as HDMI. User needs
to pass an integer value containing the valid channel positions for
all channels of the assigned PCM substream.
This operation is allowed only at PCM PREPARED state. When called in
other states, it shall return an error.
