148569fddb ASoC: hdac_hdmi: Enable playback on all enumerated ports
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.

4a3478debf ASoC: hdac_hdmi: Add jack reporting
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.

79f4e922b5 ASoC: hdac_hdmi: Create widget/route based on nodes enumerated
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.

211caab73b ASoC: hdac_hdmi: Enable DP1.2 and all converters/pins
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.

b8a54545b0 ASoC: hdac_hdmi: Add hotplug notification and read ELD
This patch uses i915 component framework to register for hotplug
notification.

In the hotplug notification, driver reads pin sense and ELD by
sending PIN_SENSE and ELD verbs over HDA bus. Once it identifies
valid pin sense and valid ELD, store the ELD into the
corresponding pin map buffer.

Also read the monitor present sense during resume and ignore the
ELD notify from graphics during PM as is done in legacy hda,

01582a8414 ASoC: arizona: fref must be limited in pseudo-fractional mode
When the FLL is in pseudo-fractional mode there is an additional
limit on fref based on the fratio, to prevent aliasing around the
Nyquist frequency. If fref exceeds this limit the refclk divider

27d6e7d1c9 ASoC: adau17x1: Cache writes when core clock is disabled
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.

d81221ff94 ASoC: arizona: Add support for SNDRV_PCM_RATE_KNOT
The Arizona CODECs support several rates that do not have simple defines
in ALSA. This patch adds support for SNDRV_PCM_RATE_KNOT so that users
can open stream at these rates. As part of this we should always set
constraints in arizona_startup, currently we only set the constraints if
we already have a clock to limit rates to that family of sample rates.
This patch updates this to set a constraint of all rates supported by
the chip if we do not already know which family of rates to limit to.
Finally we also reduce the list of rates supported in the constraints to
only include those that are supported on current parts.

This changes both the OF match table and the ACPI match table
to follow the same style, using ACPI_PTR/of_match_ptr to
make the reference conditional, and using an #ifdef to hide
the table. This also adds the missing MODULE_DEVICE_TABLE for
the OF case and adapts the formatting to the same style.

level is ON, RT286_CBJ_CTRL1(0x4f) bit 10 will be turned off.
This patch move the bit control from rt286_set_bias_level and
rt298_vref_event to rt286_jack_detect. So it will be turned on
once a jack is plugged in.

58cf279aca Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
 "Here is the bulk of GPIO changes for v4.5.

  Notably there are big refactorings mostly by myself, aimed at getting
  the gpio_chip into a shape that makes me believe I can proceed to
  preserve state for a proper userspace ABI (character device) that has
  already been proposed once, but resulted in the feedback that I need
  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()
  callback) and had to fix it.  Also, refactored generic GPIO to be
  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
  responsible for so much...

  Apart from that we're churning along as usual.

  I took some effort to test and retest so it should merge nicely and we
  shook out a couple of bugs in -next.

  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"

remove it as well.
