Last patch added infrastructure to render over all the ports,
PCM<->cvt<- pin mapping and user selection of controls. But we
still have restriction of playback on the default port alone, so
remove that.
This patch removes the hardcoding of cvt<->pin map from the dai.
Cvt and pin for a dai are now derived from the already stored pcm
list of device opened. We query connection list of a pin from
codec to validate the cvt<->pin map.
If connection list returns zero, then monitor is not connected so
fail playback.

Jack is created based on pcm devices enumerated, so we will
create Jack as "HDMI/DP, pcm=x Jack". This style is expected by
current usermode like PulseAudio and CRAS.
This patch exports an API which can be used to register Jack
based on PCM. This API also establishes the map between PCM and
cvt. Further cvt to pin mapping is established with the help of
usermode selection based on the board topology.
During device probe as the PCMs may not be registered, initial
pin sense don't report jack events. So, first time jack reporting
is done during user selection of mux control.

In skylake, HDMI codec enumerates 3 pins and 3 cvts. Stream can
be routed from any cvt to any pin based on the connection list
queried from the pin.
This patch removes the static modelling of widget/route and
creates it dynamically based on the codec widgets enumerated.
Mux widgets are added to represent the map between a cvt and pin.
Ideally the mux widgets should be created based on the connection
list queried from the pin widget. But due to HW behavior, if an
external display is not connected on a port, querying the
connection list returns zero. So create mux widgets to map all
the cvt to all pins. At runtime, playback support on a pin can be
verified based on the connection list query.
Few function in driver have additional arguments now to support
this.

Skylake supports 3 pin and 3 converter widgets. But by default
only one converter and pin widget are enabled. In skylake
platform the DP port is on a different port which is not enabled
by default. To enable playback on DP port, enable all pin and
converter widget by sending a vendor VERB for a vendor widget to
set required bits.
As we are enabling the DP support enable the DP1.2 feature as well.
Enabling DP1.2 and all widget changes are copied from patch_hdmi.c.

In some configurations, the dai registers get written before the bias
level is changed in the codec driver. This leads to a situation where
an initial write to the serial port register gets ignored, and future
writes may as well, since regmap thinks that the codec already holds the
value. More specifically, configuring the codec as i2s master would in
fact result in the codec running as slave, a situation where no i2s
clocks are generated and hence no data is transferred.
This change makes sure that regmap only caches writes when the core
clock is disabled, and syncs regmap whenever enabling the core clock
again.

Commit e22579713a ("ASoC: simple card: set cpu-dai sysclk

asoc_simple_card_hw_params fail if the operation is not supported,
although the intention clearly was to ignore ENOTSUPP. Fix it.
The patch fixes audio playback on Kirkwood / OpenRD client,

When the ssm4567 is powered up the driver calles regcache_sync() to restore
the register map content. regcache_sync() assumes that the device is in its
power-on reset state. Make sure that this is the case by explicitly
resetting the ssm4567 register map before calling regcache_sync() otherwise
we might end up with a incorrect register map which leads to undefined
behaviour.
One such undefined behaviour was observed when returning from system
suspend while a playback stream is active, in that case the ssm4567 was
kept muted after resume.

When registering a ASoC card the driver data of the parent device is set to
point to the card. This driver data is used in the
snd_soc_suspend()/resume() callbacks.
The imx-spdif driver overwrites the driver data with custom data which
causes snd_soc_suspend() to crash. Since the custom driver is not used
anywhere simply deleting the line which sets the custom driver data fixes
the issue.

This changes both the OF match table and the ACPI match table

Much of this is moving around header files from old mach directories,

Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better reflect
the fact that this is not the GPIO struct device abstraction. We will
add that soon so this would be totallt confusing.
- It was noted that the driver .get_value() callbacks was
sometimes reporting negative -ERR values to the gpiolib core, expecting
them to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than zero"
to indicate that a line was active. As some would have bit 31 set to
indicate "line active" it clashed with negative error codes. This is
fixed by the largeish series clamping values in all drivers with
!!value to [0,1] and then augmenting the code to propagate error codes
to consumers. (Includes some ACKed patches in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of() design
pattern is indeed very nice, but we want to reform the struct gpio_chip
to be a non-volative, stateless business, and keep states internal to
the gpiolib to be able to hold on to the state when adding a proper
userspace ABI (character device) further down the road. To achieve this,
drivers need a handle at the internal state that is not dependent on
their struct gpio_chip() so we add gpiochip_add_data() and
gpiochip_get_data() following the pattern of many other subsystems.
All the "use gpiochip data pointer" patches transforms drivers to this
scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that removed.
Instead of having a separate mm_gpio_chip struct for these generic
drivers, merge that into struct gpio_chip, simplifying the code and
removing the need for separate and confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from the
OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
the branch is merged here too to account for infrastructural changes).
- The sx150x driver now supports the sx1502.

to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()

simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was

- Add a void *data pointer to struct gpio_chip. The container_of()
design pattern is indeed very nice, but we want to reform the
struct gpio_chip to be a non-volative, stateless business, and keep
states internal to the gpiolib to be able to hold on to the state
when adding a proper userspace ABI (character device) further down
the road. To achieve this, drivers need a handle at the internal
state that is not dependent on their struct gpio_chip() so we add
gpiochip_add_data() and gpiochip_get_data() following the pattern
of many other subsystems. All the "use gpiochip data pointer"
patches transforms drivers to this scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that
removed. Instead of having a separate mm_gpio_chip struct for
these generic drivers, merge that into struct gpio_chip,
simplifying the code and removing the need for separate and
confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from
the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
but the branch is merged here too to account for infrastructural
changes).
- The sx150x driver now supports the sx1502"

Since the move to the new clock framework with commit 94cb7f76ca
("ARM: bcm2835: Switch to using the new clock driver support.")
this driver was no longer functional as it was manipulating the
clock registers locally without going true the framework.
This patch moves to use the new clock framework and also
moves away from the hardcoded address offsets for DMA getting
the dma-address directly from the device tree.
Note that the optimal bclk_ratio selection to avoid jitter
due to the use of fractional dividers, which is in the
current version has been removed, because not all devices
support these non power of 2 sized transfers, which resulted
in lots of (downstream) modules that use:
snd_soc_dai_set_bclk_ratio(cpu_dai, sample_bits * 2);

ASoC: Last updates for v4.5
A bunch more updates for v4.5, mainly driver work:
- More topology API enhancements from Mengdong Lin working towards
making everything more component based and being able to specify PCM
links via topology.
- Large sets driver updates from Cirrus, Intel (mainly more Skylake

- New driver for AMD ACP
- Rename PCM1792a driver to be generic pcm179x
dev pointer in struct snd_soc_pcm_runtime does not have dma_ops set. In
v4.4 kernel dma_ops would end up pointing to dummy_dma_ops in such cases.
So attempting to use such device in allocating coherent memory on aarch64
would fail.
According to commit 1dccb598df ("arm64:
simplify dma_get_ops") The current behavior of dma_get_ops is to fall
back to the global dma_ops when a device has not set its own dma_ops,
but only for DT based systems.
So, this patch fixes the driver to use correct device pointer while
allocating coherent memory, and also deletes un-necessary dma_mask setup
on soc_runtime->dev.
Without this patch lpass driver would fail with below log:

aux_dev is mainly used by the machine driver to specify analog devices,
which are registered as codecs. Making it more like a generic component
can help the machine driver to use it to specify any component with
topology info by name.
Details:
- Remove the stub 'rtd_aux' array from the soc card.
- Add a list 'aux_comp_list' to store the components of aux_devs.
And add a list head 'list_aux' to struct snd_soc_component, for adding
such components to the above list.
- Add a 'init' ops to a component for machine specific init.
soc_bind_aux_dev() will set it to be aux_dev's init. And it will be
called when probing the component.
- soc_bind_aux_dev() will also search components by name of an aux_dev,
since it may not be a codec.
- Move probing of aux_devs before checking new DAI links brought by
topology.
- Move removal of aux_devs later than removal of links. Because topology
of aux components may register DAIs and the DAI drivers will go with
removal of the aux components, we want soc_remove_link_dais() to remove
the DAIs at first.

If a device would like to use delayed suspending then PM
recommendation is to set ‘power.use_autosuspend’ flag. To allow
users to do so we need to change runtime calls in core to use
autosuspend counterparts.
For user who do not wish to use delayed suspend not setting the
device's ‘power.use_autosuspend’ flag will result in non-delayed
suspend even with these APIs which incidentally is also the default
behaviour, so only users will be impacted who opt in for this.

commit 9b8ef9f6b3 ("ASoC: dapm: Add startup & shutdown for dai_links")
Added support for calling startup on CODEC to CODEC links, however this
is called with a NULL runtime pointer. There isn't really a sensible way
to pass a valid runtime pointer to a CODEC to CODEC link at the moment,
so we need to make the startup function safe for NULL runtimes.
This patch returns from the Arizona startup function early if there is no
runtime, this is perfectly safe as all the startup function does is set
the PCM constraints for user-space which arn't relevant to a CODEC to
CODEC link anyway.

There is a status bit on RT5677_PLL1_CTRL2 and RT5677_PLL2_CTRL2.
That's why those registers are set volatile. However, the status
bit is currently not used by codec driver. So, it should be no
problem if we set them non-volatile.
The purpose of setting them non-volatile is to restore the setting
after a syspend/resume cycle.

The stream is created whilst the compressed stream is opened and a
buffer is created when the DSP powers up. It is necessary at a point
once both the DSP has powered up and the the stream has been opened to
connect a stream to a buffer on the DSP. This is done in the trigger
callback as this is after the DSP has been powered and obviously the
stream must be open. Note that whilst the connect is currently trivial

This patch adds support to the codec driver to handle mic level
detect related IRQs, and report these to user-space using a uevent
variable.
The uevent variable string "EVENT=MIC_LEVEL_DETECT" is sent to
user-space, if the mic level detect feature is enabled, and the
audio captured at the chosen mic(s) is above a certain threshold.
User-space can then handle the event accordingly (e.g. process
audio capture stream).
This method was chosen over ALSA control notification for a couple
of reasons:
1) There's no requirement here for a control to read state from.
The event is the only thing that's required and of interest.
2) tinyalsa support for control notifications does not exist so on
platforms using this over alsa-lib there is a need to add code
to support this event handling.
Another possible option would be to use the standard Jack reporting
framework but this really does not fit for this kind of event.
Finally, use of the input device framework is not being encouraged,
due to difficulties in enabling apps to access input devices, so
this has also been avoided.
