9bb1fe390d ALSA: hda - Fix beep_mode option value
The beep_mode option value was wrongly defined: it must be 0 = off and
1 = on.

Also, evaluate the beep_mode value at snd_hda_attach_beep_device()
properly so that no device is created when beep_mode=0 is given.

2dca0bba70 ALSA: hda - add beep_mode module parameter
The beep_mode parameter for snd-hda-intel module allows to choose among
different digital beep device registation to the input layer.

0 = do not register to the input layer
1 = register to the input layer all time
2 = use "Beep Switch" control exported to user space mixer applications

Also, introduce CONFIG_SND_HDA_INPUT_BEEP_MODE for default value.

13dab0808b ALSA: hda_intel: Digital PC Beep - delay input device unregistration
The massive register/unregister calls for input device layer might be
overkill. Delay unregister call by one HZ as workaround.

Also, as benefit, beep->enabled variable is changed immediately now
(not from workqueue).

123c07aedd ALSA: hda_intel: Digital PC Beep - change behaviour for input layer
Original implementation was keeping registered input device for SND_BEEP
and SND_TONE events all time. This patch changes this behaviour:
If digital PC Beep is turned off using universal control switch,
the input device is unregistered.

Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last
registered device acceping those events. It means that the HDA Intel
audio driver blocks also the internal PC Speaker device (pcspkr.c
driver) even if the HDA Beep is muted. The user can easy disable
all beeps using 'setterm -blength 0' or 'xset b off' command.

fa79796631 ALSA: hda - Fix digital beep tone calculation
The digital beep tone is calculated in two different ways depending
on the codec chip.  The standard one is using a divider, and another
one is a linear tone for IDT/STAC codecs.  Currently, only the
latter type is used for all codecs, which resulted in a wrong tone
pitch.

This patch adds the calculation of the standard HD-audio type.
Also clean-up the fields in hda_beep struct.

4d4e9bb339 ALSA: hda - Add digital beep playback switch for STAC/IDT codecs
The digital beep widget may have no mute control, and always enabling
the beep is ofen pretty annoying, especially on laptops.

This patch adds a mixer control "PC Beep Playback Switch" when there
is no mixer amp mute is found, and controls it on software.
