Currently snd_soc_dapm_add_route will continue to search the widget list
even after both the source and sink for the route have been located.
This patch breaks out of the search when both are located giving a
small improvement in probe time for drivers.

The is a missing mutex unlock on the error path in

A demux is conceptually similar to a mux. Where a mux has multiple input
and one output and selects one of the inputs to be connected to the output,
the demux has one input and multiple outputs and selects one of the outputs
to which the input gets connected.
This similarity makes it straight forward to support them in DAPM using the
existing mux support, we only need to swap sinks and sources when initially
setting up the paths.
The only slightly tricky part is that there can only be one control per
path. Since mixers/muxes are at the sink of a path and a demux is at the
source and both types want a control it is not possible to directly connect
a demux output to a mixer/mux input. The patch adds some sanity checks to
make sure that this does not happen.
Drivers who want to model hardware which directly connects a demux output
to a mixer/mux input can do this by inserting a dummy widget between the
two. E.g.:
{ "Dummy", "Demux Control", "Demux" },
{ "Mixer", "Mixer Control", "Dummy" },

Currently new widgets are appended to the beginning of the cards widget
list. This has the effect that widgets that are created while iterating
over the widget list in snd_soc_dapm_new_widgets() (like e.g. the
auto-disable widgets) are not covered during that invocation of the
function. If no further invocations of snd_soc_dapm_new_widgets() happen
these widgets will not be fully initialized and e.g. no debugfs entries are
created for them.
By adding new widgets to the end of the widget list we make sure that
widgets that are created in snd_soc_dapm_new_widgets() will still be
handled during the same snd_soc_dapm_new_widgets() invocation and are
always fully initialized.

Commit 57295073b6 ("ASoC: dapm: Implement mixer input auto-disable")
added support for autodisable controls, controls whose values are only
written to the hardware when their respective widgets are powered up.
But it only added support for controls based on the mixer abstraction.
This patch add support for mux controls (DAPM controls based on the
enum abstraction) to be auto-disabled as well. As each mux can only have
a single control, there is no need to tie the autodisable widget to the
inputs (as is done for the mixer controls) it can be tided directly to
the mux widget itself.
Note that it is assumed that the first entry in a autodisable mux
control will always represent the off state for the mux and is what the
mux will be set to whilst it is disabled.

This makes it a little easier to follow what is happening in debugfs.
Additionally is also useful in facilitating work to add autodisable
muxes because the control name is already used for the mux widget and
thus shouldn't be reused for the autodisable widget.

Use the new snd_soc_codec_force_bias_level() helper function to invoke the
bias_level callback of a driver instead of calling the callback by hand.
Currently the effect of this is the same, but having all bias level updates
go through a central place will allow us to move more of the bias level
management into the DAPM core.

Signed-off-by: Mark Brown <broonie@kernel.org>
Currently drivers are responsible for managing the bias_level field of
their DAPM context. The DAPM state itself is managed by the DAPM core
though and the core has certain expectations on how and when the bias_level
field should be updated. If drivers don't adhere to these undefined
behavior can occur.
This patch adds a few helper functions for manipulating the DAPM context
state, each function with a description on when it should be used and what
its effects are. This will also help us to move more of the bias_level
management from drivers to the DAPM core.
For convenience also add snd_soc_codec_* wrappers around these helpers.

There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level
to the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's

Merge tag 'asoc-fix-v4.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound
Pull last-minute ASoC fix from Mark Brown:
"This patch backs out a change that came in during the merge window
which selects a configuration for GPIO4 on pcm512x CODECs that may not
be suitable for all systems using the device. Changes for v4.1 will
make this properly configurable but for now it's safest to revert to
the v3.19 behaviour and leave the pin configuration alone.
Sorry for sending this direct at the last minute but due to the GPIO
misuse it'd be really good to get it in the release and I'd not
realised it hadn't been sent yet - between some travel, a job change
and other non-urgent fixes coming in I'd lost track of the urgency.
It's been in -next for several weeks now, is isolated to the driver
and fairly clear to inspection"
* tag 'asoc-fix-v4.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound:
ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
The r-car sound driver only works when CONFIG_OF is set, and
after a recent change has a compile-time dependency as well:
sound/built-in.o: In function `rsnd_dma_request_channel':
:(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'
This could be fixed either by adding a static inline wrapper
for the function, or by adding a Kconfig dependency. This
implements the second approach, which seems appropriate
because the driver in fact has a hard dependency.

Currently GPIO4 is hardcoded to output the pll-lock signal.
Unfortunately this is after the pll-out GPIO is configured which
is selectable in the device tree. Therefore it is not possible to
use GPIO4 for pll-out. Therefore this patch removes the
configuration of GPIO4.
