ASoC: rt5677: Allow VAD to be shut on/off at all times
Due to limitations of the clocking configuration, we have no way of
scheduling our hibernation before the bdw dsp hibernates. This causes
issues when the system suspends with an open stream. We need userspace
to toggle the kcontrol before we are suspended so that any writes on
suspend are not lost and we don't corrupt the regmap.

ASoC: rt5677: Disable irq at suspend
The irq is disabled at suspend to avoid running the threaded irq
handler after the codec has been powered off. At resume, codec irq is
re-enabled and the interrupt status register is checked to see if
headphone has been pluggnd/unplugged while the device is suspended.

There is still a chance that the headphone gets enabled or disabled
after the codec is suspended. disable_irq syncs the threaded irq
handler, but soc-jack's threaded irq handler schedules a delayed
work to poll gpios (for debounce). This is still OK. The codec won't
be powered back on again because all audio paths have been suspended,
and there are no force enabled supply widgets (MICBIAS1 is disabled).
The gpio status read after codec power off could be wrong, so the
gpio values are checked again after resume.

ASoC: rt5677: Stop and restart DSP over suspend/resume
MCLK1 gets disabled at suspend and re-enabled at resume. Before
MCLK1 is re-enabled, if the DSP is already on (either the DSP was
left on during suspend, or the DSP is turned on early at resume),
i2c register read returns garbage and corrupts the regmap cache.

This patch stops the DSP before suspend and restarts it after
resume with a dalay to ensure MCLK is on while loading firmware.

ASoC: rt5677: Mark reg RT5677_PWR_ANLG2 as volatile
The codec dies when RT5677_PWR_ANLG2(MX-64h) is set to 0xACE1
while it's streaming audio over SPI. The DSP firmware turns
on PLL2 (MX-64 bit 8) when SPI streaming starts.  However regmap
does not believe that register can change by itself. When
BST1 (bit 15) is turned on with regmap_update_bits(), it doesn't
read the register first before write, so PLL2 power bit is
cleared by accident.

Marking MX-64h as volatile in regmap solved the issue.

ASoC: rt5677: Enable jack detect while DSP is running
Before a hotword is detected, GPIO1 pin is configured as IRQ
output so that jack detect works. When a hotword is detected,
the DSP firmware configures the GPIO1 pin as GPIO1 and
drives a 1. rt5677_irq() is called after a rising edge on
the GPIO1 pin, due to either jack detect event or hotword
event, or both. All possible events are checked and handled
in rt5677_irq() where GPIO1 pin is configured back to IRQ
output if a hotword is detected.

ASoC: rt5677: Load firmware via SPI using delayed work
The firmware rt5677_elf_vad is an ELF binary obtained from
request_firmware(). Sections of the ELF are loaded to
the DSP via SPI. A model (e.g. en_us.mmap) can optionally be
loaded to the DSP at RT5677_MODEL_ADDR to overwrite the
baked-in model in rt5677_elf_vad.

Then we switch to DSP mode, load firmware, and let DSP run.
When a hotword is detected, an interrupt is fired and
rt5677_irq() is called. When 'DSP VAD Switch' is turned off,
the codec is set back to normal mode.

The kcontrol 'DSP VAD Switch' is automatically enabled/disabled
when the hotwording PCM stream is opened/closed.

ASoC: rt5677: keep analog power register at SND_SOC_BIAS_OFF
Instead of clearing RT5677_PWR_ANLG2 (MX-64h) to 0 at SND_SOC_BIAS_OFF,
we only clear the RT5677_PWR_CORE bit which is set at SND_SOC_BIAS_PREPARE.
MICBIAS control bits are left unchanged.

This fixed the bug where if MICBIAS1 widget is forced on, MICBIAS
control bits will be cleared at suspend and never turned back on again,
since DAPM thinks the widget is always on.

ASoC: rt5677: handle concurrent interrupts
The rt5677 driver writes to the IRQ control register within the IRQ
handler in order to flip the polarity of the interrupts that have been
signalled.  If an interrupt fires in the interval between the
regmap_read and the regmap_write, it will not trigger a new call to
rt5677_irq.

Add a bounded loop to rt5677_irq that keeps checking interrupts until
none are seen, so that any interrupts that are signalled in that
interval are correctly handled.

ASoC: rt5677: clear interrupts by polarity flip
The rt5677 jack detection function has a requirement that the polarity
of an interrupt be flipped after it fires in order to clear the
interrupt.

This patch implements an irq_chip with irq_domain directly instead of
using regmap-irq, so that interrupt source line polarities can be
flipped in the irq handler.

The reason that this patch does not add this feature within regmap-irq
is that future patches will add hotword detection support to this irq
handler. Those patches will require adding additional logic that would
not make sense to have in regmap-irq.

have the required information provided via ACPI.  Reintroduce the I2C
device ID to restore sound functionality on on the Chromebook 'Samus'
model.

[ More background note:
 the commit a36afb0ab6 ("ASoC: rt5677: Introduce proper table...")
 moved the i2c ID probed via ACPI ("RT5677CE:00") to a proper
 acpi_device_id table.  Although the action itself is correct per se,
 the overseen issue is the reference id->driver_data at
 rt5677_i2c_probe() for retrieving the corresponding chip model for
 the given id.  Since id=NULL is passed for ACPI matching case, we get
 an Oops now.

 We already have queued more fixes for 4.14 and they already address
 the issue, but they are bigger changes that aren't preferable for the
 late 4.13-rc stage.  So, this patch just papers over the bug as a
 once-off quick fix for a particular ACPI matching.  -- tiwai ]

Bhumika Goyal a180ba45b1 ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

Javier Martinez Canillas 7b87463edf ASoC: rt5677: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Linus Torvalds 58cf279aca GPIO bulk updates for the v4.5 kernel cycle:
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.

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

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.
