If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally. So
HAS_IOPORT_MAP is the better name for this.
Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.
The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available. I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.
The changes in this commit were done using:
$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

Pull ARM SoC late cleanups from Arnd Bergmann:
"These could not be part of the first cleanup branch, because they
either came too late in the cycle, or they have dependencies on other
branches. Important changes are:
- The integrator platform is almost multiplatform capable after some
reorganization (Linus Walleij)
- Minor cleanups on Zynq (Michal Simek)
- Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks
bindings are rearranged"

Merge "Samsung PM related 2nd updates for v3.15" from Kukjin Kim:
From Tomasz Figa <t.figa@samsung.com>:
Current Samsung PM code is heavily unprepared for multiplatform
systems. The design implies accessing functions and global
variables defined in particular mach- subdirectory from common
code in plat-, which is not allowed when building ARCH_MULTIPLATFORM.
In addition there is a lot of forced code unification, which makes
common function handle any possible quirks of all supported SoCs.
In the end this design turned out to not work too well, ending with
a lot of empty functions exported from mach-, just because code in
common pm.c calls them. Moreover, recent trend of moving lower level
suspend/resume code to proper drivers, like pinctrl or clk, made a
lot of code there redundant, especially on DT-only platforms like
Exynos.
Note that this branch is based on previous tags/samsung-pm-1 and merge
tags/samsung-cleanup-2 because of fix build error from recent changes
of <linux/serial_s3c.h>

Since Exynos SoCs does not follow most of the semantics of older SoCs
when configuring the system to enter sleep, there is no reason to rely
on the legacy Samsung PM core anymore.
This patch adds local Exynos suspend ops and removes all the code left
unnecessary. As a side effect, suspend support on Exynos becomes
multiplatform-friendly.

To separate legacy PM code from generic helpers, this patch moves the

that is compiled always when CONFIG_PM_SLEEP is enabled, to allow

helpers.

Not all Samsung SoC platforms are going to use the legacy Samsung PM
code enabled by CONFIG_SAMSUNG_PM_DEBUG. To allow using Samsung PM debug
helpers on such platforms, related code is moved to separate file and
a plat/pm-common.h header is added to separate legacy and generic code.

This patch modifies Samsung PM debug helpers to use a multiplatform
friendly way of getting base address of debug UART port, so instead
of using a per-mach static macro, a generic debug_ll_addr() helper
is used.

The only SoC that does not have DIVSLOT register is S3C2410, so instead
of exporting a variable for platforms to set if DIVSLOT register should
be preserved, it's enough to simply check whether we are running on
a S3C2410 instead.

Due to the S3C2410 SoC being quite different from other S3C24xx SoCs
in some aspects, such as availability of DIVSLOT register in its UART
blocks, there is a need sometimes to check whether we are running on
this SoC, not just the S3C24xx series. This patch adds soc_is_s3c2410()
helper function for this purpose.

Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions (Kumar Gala)
- A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
- Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
- mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
- at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people)"

The Samsung pm_check code uses the crc32 library code, which can
be built as a loadable module, in which case we get a link error

A better solution is to use 'select CRC32', which is what all

Pull spi updates from Mark Brown:
"A respun version of the merges for the pull request previously sent
with a few additional fixes. The last two merges were fixed up by
hand since the branches have moved on and currently have the prior
merge in them.
Quite a busy release for the SPI subsystem, mostly in cleanups big and
small scattered through the stack rather than anything else:
- New driver for the Broadcom BC63xx HSSPI controller
- Fix duplicate device registration for ACPI
- Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
changes upon which the transiton depends)
- Some small optimisations to reduce the amount of time we hold locks
in the datapath, eliminate some redundant checks and the size of a
spi_transfer
- Lots of fixes, cleanups and general enhancements to drivers,
especially the rspi and Atmel drivers"

Pull ARM SoC cleanups from Olof Johansson:
"This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,

* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared

* Tegra DMA refactoring, which are shared branches with the DMA tree.

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

This patch adds all required platform-specific data and initialization
code to support the generic amba-pl08x driver on S3C64xx SoCs.
Also some compatibility definitions are added to make the transition
from legacy API to DMA engine easier. The biggest hack here is passing
const char * pointers through DMA resource, casted to unsigned long,
but this is how Samsung DMA wrappers (used to support both s3c-dma and
DMA engine in drivers) are designed.

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.

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.

Pull pwm changes from Thierry Reding:
"Mostly bug fixes and clean up. There is a new driver, which is
actually moving a custom PWM driver from drivers/misc.
The majority of the patches are enhancements to the device tree
support in the pwm-backlight driver. Backlights can now additionally
be powered using a regulator and enabled using a GPIO in addition to
just the PWM input"

The GPIO API defines 0 as being a valid GPIO number, so this field needs
to be initialized explicitly.
