ASoC automatically creates snd_soc_dapm_dai_in and snd_soc_dapm_dai_out
widgets for DAI drivers, and adds them to the list. Later on, ASoC
creates automatic routes between these widgets and a widget with a
stream name.
We look for a snd_soc_dapm_dai_in or snd_soc_dapm_dai_out widget, and
use this to obtain the DAI structure. We then scan all widgets for
any with a stream name refering to either the capture or the playback
stream, and create routes.
If you have both a snd_soc_dapm_dai_in and a snd_soc_dapm_dai_out
referring to the same DAI structure, this ends up creating one set of
routes for the DAI for the snd_soc_dapm_dai_in widget, and a duplicated
set of routes for the snd_soc_dapm_dai_out widget.
Fix this by checking that the stream name for the widget matches the
DAI widget name.

Powering down PLL before switching to a mode that does not use it
is a bad idea. It would cause the SGTL5000 be without internal
clock supply, especially on the I2C interface, which would make
subsequent access to it fail.
Thus, in case of not using PLL any longer, first set the mode
control, then power down PLL.

Some devices have the problem that if a internal audio signal source is disabled
the output of the source becomes undefined or goes to a undesired state (E.g.
DAC output goes to ground instead of VMID). In this case it is necessary, in
order to avoid unwanted clicks and pops, to disable any mixer input the signal
feeds into or to active a mute control along the path to the output. Often it is
still desirable to expose the same mixer input control to userspace, so cerain
paths can sill be disabled manually. This means we can not use conventional DAPM
to manage the mixer input control. This patch implements a method for letting
DAPM overwrite the state of a userspace visible control. I.e. DAPM will disable
the control if the path on which the control sits becomes inactive. Userspace
will then only see a cached copy of the controls state. Once DAPM powers the
path up again it will sync the userspace setting with the hardware and give
control back to userspace.
To implement this a new widget type is introduced. One widget of this type will
be created for each DAPM kcontrol which has the auto-disable feature enabled.
For each path that is controlled by the kcontrol the widget will be connected to
the source of that path. The new widget type behaves like a supply widget,
which means it will power up if one of its sinks are powered up and will only
power down if all of its sinks are powered down. In order to only have the mixer
input enabled when the source signal is valid the new widget type will be
disabled before all other widget types and only be enabled after all other
widget types.
E.g. consider the following simplified example. A DAC is connected to a mixer
and the mixer has a control to enable or disable the signal from the DAC.
+-------+
+-----+ | |
| DAC |-----[Ctrl]-| Mixer |
+-----+ : | |
| : +-------+
| :
+-------------+
| Ctrl widget |
+-------------+
If the control has the auto-disable feature enabled we'll create a widget for
the control. This widget is connected to the DAC as it is the source for the
mixer input. If the DAC powers up the control widget powers up and if the DAC
powers down the control widget is powered down. As long as the control widget
is powered down the hardware input control is kept disabled and if it is enabled
userspace can freely change the control's state.

CODECs without any outputs now remain powered down, which means any
paths to these codecs also remain powered down.
Add an always-enabled output pin widget to the spdif transceiver codec.
This enables DAPM to correctly identify that the spdif transceiver is

any links from the CPU DAI to the S/PDIF transceiver.

A fixup for Apple Mac Mini was lost during the adaption to the generic
parser because the fallback for the generic ID 8384:7680 was dropped,
and it resulted in the silence output (and maybe other problems).
Unfortunately, just adding the missing subsystem ID wasn't enough, in
this case. The subsystem ID of this machine is 0000:0100 (what Apple
thought...?), and since snd_hda_pick_fixup() doesn't take the vendor
id zero into account, the driver ignored this entry. Now it's fixed
to regard the vendor id zero as a valid value.

calling dapm_create_or_share_mixmux_kcontrol() with a path struct that points
right in the middle of the widget struct and by trying to modify the path the
widgets memory will become corrupted. Fix this by using list_emtpy() to check if

For some reason, the DAC/ADCs are not being powered up when I try and
use the UDA1341 driver; this used to work. Looking back in the git
history, I don't see anything obvious which would cause this
regression.
However, from dumping the register writes, it seems that the codec is
powered down, and nothing calls set_bias_level to wake the codec up.
Moreover, this driver hasn't had DAPM support added to it, which
prevents platform drivers from taking advantage of DAPMs facilities.
So, let's add DAPM support to the driver.
As we move the power control for the DAC/ADC into DAPM, we no longer
need it in set_bias_level() - this function just becomes a way to
manipulate the power control and sync the register cache with the
hardware at the appropriate point.
