4ea6fbc8eb ALSA: hda - Add patch module option
Added the patch module option to apply a "patch" as a firmware to
modify pin configurations or give additional hints to the driver
before actually initializing and configuring the codec.

This can be used as a workaround when the BIOS doesn't give sufficient
information or give wrong information that doesn't match with the real
hardware setup, until it's fixed statically in the driver via a quirk.

812a2cca29 ALSA: hda - Split codec->name to vendor and chip name strings
Split the name string in hda_codec struct to vendor_name and chip_name
strings to be stored directly from the preset name.
Since mostly only the chip name is referred in many patch_*.c, this
results in the reduction of many codes in the end.

bb6ac72fb1 ALSA: hda - power up before codec initialization
Change the power state of each widget before starting the initialization
work so that all verbs are executed properly.

Also, keep power-up during hwdep reconfiguration.

43b62713f6 ALSA: hda - Add hint string helper functions
Added snd_hda_get_hint() and snd_hda_get_bool_hint() helper functions
to retrieve a hint value.

Internally, the hint is stored in a pair of two strings, key and val.

1289e9e8b4 ALSA: hda - Modularize HD-audio driver
Split the monolithc HD-audio driver into several pieces:
 - snd-hda-intel   HD-audio PCI controller driver; loaded via udev
 - snd-hda-codec   HD-audio codec bus driver
 - snd-hda-codec-* Specific HD-audio codec drivers

When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
looks up the codec vendor ID and loads the corresponding codec module
automatically via request_module().

When built in a kernel, each codec drivers are statically hooked up
before probing the PCI.

This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
information for each driver, and driver-linking codes between
codec-bus and codec drivers.

TODO:
  - Avoid EXPORT_SYMBOL*() when built-in kernel
  - Restore __devinit appropriately depending on the condition

529bd6c4a6 ALSA: hda - Fix PCM reconfigure
The reconfiguration of PCM affected all PCM streams on the bus, but
this this should be done rather only for the target codec.

This patch does the following:
- introduce bitmap indicating the PCM device usages on a hda_bus
- refactor the PCM build functions
- fix __devinit prefix in some fucntions
- add a proper ifdef around HDA-reconfig-specific functions

1e1be4329f ALSA: hda - Add hints for reconfig
This patch adds the "hints" for reconfiguring codecs.  The hints
are simply string arrays and can be freely used/parsed by the codec
patch.  The hints can be input via hwdep sysfs files.

This patch enables the additional init verbs for each codec.  The verbs
can be entered via hwdep sysfs file.  These verbs are executed at
reconfiguring the codec for non-standard setups like overriding
the pin-defcfg.

9004acc70e [ALSA] Remove sound/driver.h
This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.
