Now that the kernel provides DIV_ROUND_CLOSEST_ULL(), drop the internal
implementation and use the kernel one.

Pull sound updates from Takashi Iwai:
"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
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC

Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func
snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11) when adding
the verb so that its peer vendor 'get' verb is actually added. This can avoid
I/O error when writing the 'set' verb thru remap, since HD-A regmap internally
looks up a writable vendor verb with GET bit set at first.

ASoC: Updates for v4.1
More updates for v4.1, pretty much all drivers:
- Lots of cleanups from Lars, mainly moving things from the CODEC level

Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
and to rt5670 from Bard.
- Support for some non-DSP Qualcomm platforms, Google's Storm
platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.

Although some races in runtime PM refcount was fixed by the commit
[664c715573c2: ALSA: hda - Work around races of power up/down with
runtime PM], there is still a race in the following case:
CPU0: CPU1 :
runtime suspend:
codec->in_pm = 1
snd_hdac_power_up_pm():
pm_runtime_get_sync() skipped
suspend finished:
codec->in_pm = 0
snd_hdac_power_down_pm():
pm_runtime_put_*() is called!
For avoiding this situation, increment in_pm flag atomically when it's
non-zero, and decrement accordingly, to ensure that in_pm is set
consistently for the whole concurrent operations.
Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are
lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm()
to sound/hda/hdac_device.c as no inline functions.

userspace element
An element instance can have several elements with the same feature.
Some userspace applications can add such an element instance by add
operation with the number of elements. Then, the element instance
gets a memory object to keep states of these elements.
But the element instance has just one memory object for the elements.
This causes the same result to each read/write operations to the
different elements.
This commit fixes this bug by allocating enough memory objects to the
element instance for each of elements.

ASoC: Last minute fix for v4.0
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.

Some callers of n810_ext_control() pass the card DAPM context and some pass

the function are in the card's context, always passing it is the obvious
choice.

The dapm field of the snd_soc_codec struct will eventually be removed
(replaced with the DAPM context from the component embedded inside the
CODEC). Replace its usage with the card's DAPM context. The idea is that
DAPM is hierarchical and with the card at the root it is possible to access
widgets from other contexts through the card context.

The SND_AT91_SOC_SAM9G20_WM8731 and SND_AT91_SOC_SAM9X5_WM8731 machine
driver symbols select SND_SOC_WM8731 which depends on SND_SOC_I2C_AND_SPI.
So the machine driver symbols need to depend on SND_SOC_I2C_AND_SPI as well,
otherwise we might end up with a invalid configuration, which will sooner or
later upset the randconfig auto-builders.

The commit [39d118677baa: ALSA: ctl: evaluate macro instead of
numerical value] replaced the numbers with constants, but one place
was replaced wrongly with a different type. Fixed now.

Adds Microsoft LifeCam Cinema USB ID to the snd_usb_get_sample_rate_quirk list as the Lifecam Cinema does not appear to support getting the sample rate.
Fixes the issue where the LifeCam Cinema would wait for USB timeout and log the message "cannot get freq at ep 0x82" when accessed.
Addresses bug report https://bugzilla.kernel.org/show_bug.cgi?id=95961.

readv() and writev() should _not_ ignore all but the first ->iov_len,
among other things. Really weird abuse of those syscalls - it
expects a vector element per channel, with identical lengths (it
actually assumes them to be identical - no checking is done).
readv() and writev() are really bad match for that. Unfortunately,
userland API is userland API and we can't do anything about them.
Converted to ->read_iter/->write_iter. Please, _please_ don't do
anything of that kind when designing new interfaces.

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"

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.

The optical ports on the E-mu 1010 (and dock) can be configured
for ADAT- or S/PDIF-mode, which is currently hardcoded to ADAT.
Add two mixer elements to expose this setting.
Tested on an E-mu 1010 PCIe with connected Micro Dock.
