Since the "recent" changes, am335x_tsc_se_update() has no longer any
users outside of this file so make it local.

Pull sound updates from Takashi Iwai:
"It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam"

The register states now tracked by the regmap implementation in the core which
makes the reset registers functionality 'redundant' since we know the state
of the registers now all the time.

If the regcache is enabled on the regmap module drivers might need to access
to HW register(s) in certain cases in cache bypass mode.
As an example of this is the audio block's ANAMICL register. In normal
operation the content can be cached but during initialization one bit from
the register need to be monitored. With the twl_set_regcache_bypass() the
client driver can switch regcache bypass on and off when it is needed so
we can utilize the regcache for more registers.

This patch adds a new field to the dma_slave_caps struct which indicates the
granularity with which the driver is able to update the residue field of the
dma_tx_state struct. Making this information available to dmaengine users allows
them to make better decisions on how to operate. E.g. for audio certain features
like wakeup less operation or timer based scheduling only make sense and work
correctly if the reported residue is fine-grained enough.
Right now four different levels of granularity are supported:
* DESCRIPTOR: The DMA channel is only able to tell whether a descriptor has
been completed or not, which means residue reporting is not supported by
this channel. The residue field of the dma_tx_state field will always be
0.
* SEGMENT: The DMA channel updates the residue field after each successfully
completed segment of the transfer (For cyclic transfers this is after each
period). This is typically implemented by having the hardware generate an
interrupt after each transferred segment and then the drivers updates the
outstanding residue by the size of the segment. Another possibility is if
the hardware supports SG and the segment descriptor has a field which gets
set after the segment has been completed. The driver then counts the
number of segments without the flag set to compute the residue.
* BURST: The DMA channel updates the residue field after each transferred
burst. This is typically only supported if the hardware has a progress
register of some sort (E.g. a register with the current read/write address
or a register with the amount of bursts/beats/bytes that have been
transferred or still need to be transferred).

The IP in DRA7xx is similar to the IP found in TI81xxAM3xxx/AM4xxx type of
SoCs but it is is integrated with sDMA instead of eDMA. The suitable pcm
driver for DRA7xx is the omap-pcm driver which is using dmaengine.
In the driver we can configure both dma related structures used for eDMA and
sDMA. The only thing we need to make sure that we set the correct dma_data
at startup with snd_soc_dai_set_dma_data()

dma_request_slave_channel() simply returns NULL whenever DMA channel
lookup fails. Lookup could fail for two distinct reasons:
a) No DMA specification exists for the channel name.
This includes situations where no DMA specifications exist at all, or
other general lookup problems.
b) A DMA specification does exist, yet the driver for that channel is not
yet registered.
Case (b) should trigger deferred probe in client drivers. However, since
they have no way to differentiate the two situations, it cannot.
Implement new function dma_request_slave_channel_reason(), which performs
identically to dma_request_slave_channel(), except that it returns an
error-pointer rather than NULL, which allows callers to detect when
deferred probe should occur.
Eventually, all drivers should be converted to this new API, the old API
removed, and the new API renamed to the more desirable name. This patch
doesn't convert the existing API and all drivers in one go, since some
drivers call dma_request_slave_channel() then dma_request_channel() if
that fails. That would require either modifying dma_request_channel() in
the same way, or adding extra error-handling code to all affected
drivers, and there are close to 100 drivers using the other API, rather
than just the 15-20 or so that use dma_request_slave_channel(), which
might be tenable in a single patch.
acpi_dma_request_slave_chan_by_name() doesn't currently implement
deferred probe. It should, but this will be addressed later.

Pull bulk pin control changes from Linus Walleij:
"This has been queued and tested for a while. Lots of action here,
like in the GPIO tree, embedded stuff like this is really hot now it
seems. Details in the signed tag. I'm especially happy about the
Qualcomm driver as it is used in such a huge subset of mobile handsets
out there, and these platforms in general need better upstream support
- New driver for the Qualcomm TLMM pin controller and its msm8x74
subdriver.
- New driver for the Broadcom Capri BCM281xx SoC.
- New subdriver for the imx25 pin controller.
- New subdriver for the Tegra124 pin controller.
- Lock GPIO lines as IRQs for select combined pin control and GPIO
drivers for baytrail and sirf.
- Some semi-big refactorings and extenstions to the sirf driver.
- Lots of patching, cleanup and fixing in the Renesas "PFC" driver
and associated subdrivers as usual. It is settling down a little
bit now it seems.
- Minor fixes and incremental updates here and there as usual"

Pull GPIO tree bulk changes from Linus Walleij:
"A big set this merge window, as we have much going on in this
subsystem. The changes to other subsystems (notably a slew of ARM
machines as I am doing away with their custom APIs) have all been
ACKed to the extent possible.
Major changes this time:
- Some core improvements and cleanups to the new GPIO descriptor API.
This seems to be working now so we can start the exodus to this
API, moving gradually away from the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move the few
GPIO ACPI clients we have to the GPIO descriptor API right *now*
before we go any further. We actually managed to contain this
*before* we started to litter the kernel with yet another hackish
global numberspace for the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have been
migrated to use the GPIO descriptors rather than fixed number
assignments. Tegra machine has been migrated as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those
should be really good examples of how I expect a nice GPIO driver
to look these days.
- Do away with custom GPIO implementations on a major part of the ARM
machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the
same in the horribly convoluted Samsung S3C include forest. We
expect to continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line is used
for IRQs and can then enforce some semantics such as disallowing a
GPIO line marked as in use for IRQ to be switched to output mode.
- Drop all use of irq_set_chip_and_handler_name(). The name provided
in these cases were just unhelpful tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em 74x164 and
msm drivers.
- Some non-urgent bug fixes here and there, duplicate #includes and
that usual kind of cleanups"
Fix up broken Kconfig file manually to make this all compile.

When refactoring and breaking out the includes for the
machine-specific GPIO configuration, two files were created
in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as
that namespace shall be used for defining data exchanged
between machines and drivers, using it for these broad macros
and config settings is wrong.
Move the headers back into the machine-local
<mach/gpio-samsung.h> file and think about the next step.

Now that all users of acpi_gpio.h have been moved to use either the GPIO
descriptor interface or to the internal gpiolib.h we can get rid of
acpi_gpio.h entirely.
Once this is done the only interface to get GPIOs to drivers enumerated
from ACPI namespace is the descriptor based interface.

Instead of asking each driver to register to ACPI events we can just call
acpi_gpiochip_register_interrupts() for each chip that has an ACPI handle.
The function checks chip->to_irq and if it is set to NULL (a GPIO driver
that doesn't do interrupts) the function does nothing.
We also add the a new header drivers/gpio/gpiolib.h that is used for
functions internal to gpiolib and add ACPI GPIO chip registering functions
to that header.
Once that is done we can remove call to acpi_gpiochip_register_interrupts()
from its only user, pinctrl-baytrail.c

This isolates the custom S3C64xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x64xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.
Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead
roof the number of GPIOs for this platform:
First sum up all the GPIO banks from A to Q: 187 GPIOs.
Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA,
128, so in total maximum 187+16+128 = 331 GPIOs, so let's
take the same roof as for S3C24XX: 512. This way we can do
away with the GPIO calculation macros for GPIO_BOARD_START,
BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

This isolates the custom S3C24xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x24xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.
We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff.
The biggest this can ever be for the S3C24XX is
CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or
CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512
is the absolute roof value on this platform. So we set
the size of ARCH_NR_GPIO to this and the GPIOs array will
fit any S3C24XX platform, as per pattern from other archs.
ChangeLog v2->v3:
- Move the movement of the S3C64XX gpio.h file out of
this patch and into the follow-up patch where it belongs.
ChangeLog v1->v2:
- Added an #ifdef ARCH_S3C24XX around the header inclusion
in drivers/gpio/gpio-samsung.c as we would otherwise
have colliding definitions when compiling S3C64XX.
- Rename inclusion guard in the header file.

Change the format of the platform GPIO lookup tables to make them less
confusing and improve lookup efficiency.
The previous format was a single linked-list that required to compare
the device name and function ID of every single GPIO defined for each
lookup. Switch that to a list of per-device tables, so that the lookup
can be done in two steps, omitting the GPIOs that are not relevant for a
particular device.
The matching rules are now defined as follows:
- The device name must match *exactly*, and can be NULL for GPIOs not
assigned to a particular device,
- If the function ID in the lookup table is NULL, the con_id argument of
gpiod_get() will not be used for lookup. However, if it is defined, it
must match exactly.
- The index must always match.

defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

The Nomadik I2C controller needs to have the slave set-up time
configured based off the clock used to drive the I2C bus block.
Currently this is done with static assignments assuming that the
block is clocked 48MHz which is pretty likely to be bug-prone.
Calculate the SLSU from the equation given in the datasheet
instead.
