Takashi Iwai b989d0444b ALSA: hda - Enable sysfs attributes without CONFIG_SND_HDA_RECONFIG
Some sysfs attributes like init_pin_configs or vendor_name are really
basic and should be available no matter whether the codec driver is
re-configurable or not.  Put them out of #ifdef
CONFIG_SND_HDA_RECONFIG and allow the read-only accesses.

Takashi Iwai 648a8d276e ALSA: hda - Add sysfs to codec object, too
We have currently sysfs attributes for each hwdep, but basically these
should belong to the codec itself, per se.  Let's add them to the
codec object while keeping them for hwdep as is for compatibility.

While we are at it, split the sysfs-related stuff into a separate
source file, hda_sysfs.c, and keep only the stuff necessary for hwdep
in hda_hwdep.c.

Takashi Iwai 13aeaf6801 ALSA: hda - Create own device struct for each codec
As the HD-audio is treated individually in each codec driver, it's
more convenient to assign an own struct device to each codec object.
Then we'll be able to use dev_err() more easily for each codec, for
example.

For achieving it, this patch just creates an object "hdaudioCxDy".
It belongs to sound class instead of creating a new bus, just for
simplicity, at this stage.  No pm ops is implemented in the device
struct level but currently it's merely a container.  The PCM and hwdep
devices are now children of this codec device.

Takashi Iwai caa751bad4 ALSA: Create sysfs attribute files via groups
Instead of calling each time device_create_file(), create the groups
of sysfs attribute files at once in a normal way.  Add a new helper
function, snd_get_device(), to return the associated device object,
so that we can handle the sysfs addition locally.

Since the sysfs file addition is done differently now,
snd_add_device_sysfs_file() helper function is removed.

Takashi Iwai ef8e39b51f ALSA: hda - Fix undefined symbol due to builtin/module mixup
Even after the fix for leftover kconfig handling (commit f8f1becf),
the current code still doesn't handle properly the builtin/module
mixup case between the core snd-hda-codec and other codec drivers.
For example, when CONFIG_SND_HDA_INTEL=y and
CONFIG_SND_HDA_CODEC_HDMI=m, it'll end up with an unresolved symbol
snd_hda_parse_hdmi_codec.  This patch fixes the issue.

Now codec->parser points to the parser object *only* when a module
(either generic or HDMI parser) is loaded and bound.  When a builtin
symbol is used, codec->parser still points to NULL.  This is the
difference from the previous versions.

Takashi Iwai 7fe307117d ALSA: hda - Fix inconsistent Mic mute LED
The current code for controlling mic mute LED in patch_sigmatel.c
blindly assumes that there is a single capture switch.  But, there can
be multiple multiple ones, and each of them flips the state, ended up
in an inconsistent state.

For fixing this problem, this patch adds kcontrol to be passed to the
hook function so that the callee can check which switch is being
accessed.  In stac_capture_led_hook(), the state is checked as a
bitmask, and turns on the LED when all capture switches are off.

Stephen Warren 75fae117a5 ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled
Commit 384a48d715 "ALSA: hda: HDMI: Support codecs with fewer cvts
than pins" dynamically enabled each pin widget's PIN_OUT only when the
pin was actively in use. This was required on certain NVIDIA CODECs for
correct operation. Specifically, if multiple pin widgets each had their
mux input select the same audio converter widget and each pin widget had
PIN_OUT enabled, then only one of the pin widgets would actually receive
the audio, and often not the one the user wanted!

However, this apparently broke some Intel systems, and commit
6169b67361 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
CODECs.

This change supports either dynamic or static handling of PIN_OUT,
selected by a flag set up during CODEC initialization. This flag is
enabled for all recent NVIDIA GPUs.

Takashi Iwai 3a00c6605b ALSA: hda/conexant - Re-implement OLPC XO workarounds via fixup
OLPC XO needs a few special handling.  Now these are implemented as a
fixup to the generic parser.

Obviously, the DC BIAS mode had to be added manually.  This is mainly
implemented in the mic_autoswitch hook, where the mic pins are
overwritten depending on the DC bias mode.  This also required the
override of the mic boost control, since the mic boost is applied only
when the DC mode is disabled.

In addition, the mic pins must be set dynamically at recording time
because these also control the LED.
