spi: spi-gpio: Rewrite to use GPIO descriptors
This converts the bit-banged GPIO SPI driver to looking up and
using GPIO descriptors to get a handle on GPIO lines for SCK,
MOSI, MISO and all CS lines.

All existing board files are converted in one go to keep it all
consistent. With these conversions I rarely find any interrim
steps that makes any sense.

Device tree probing and GPIO handling should work like before
also after this patch.

For board files, we stop using controller data to pass the GPIO
line for chip select, instead we pass this as a GPIO descriptor
lookup like everything else.

In some s3c24xx machines the names of the SPI devices were set to
"spi-gpio" rather than "spi_gpio" which can never have worked, I
fixed it working (I guess) as part of this patch set. Sometimes
I wonder how this code got upstream in the first place, it
obviously is not tested.

mach-s3c64xx/mach-smartq.c has the same problem and additionally
defines the *same* GPIO line for MOSI and MISO which is not going
to be accepted by gpiolib. As the lines were number 1,2,2 I assumed
it was a typo and use lines 1,2,3. A comment gives awat that line 0
is chip select though no actual SPI device is provided for the LCD
supposed to be on this bit-banged SPI bus. I left it intact instead
of just deleting the bus though.

Kill off board file code that try to initialize the SPI lines
to the same values that they will later be set by the spi_gpio
driver anyways. Given the huge number of weird things in these
board files I do not think this code is very tested or put in
with much afterthought anyways.

In order to assert that we do not get performance regressions on
this crucial bing-banged driver, a ran a script like this dumping the
Ilitek ILI9322 regmap 10000 times (it has no caching obviously) on
an otherwise idle system in two iterations before and after the
patches:

 #!/bin/sh
 for run in `seq 10000`
 do
     cat /debug/regmap/spi0.0/registers > /dev/null
 done

Before the patch:

time test.sh
real    3m 41.03s
user    0m 29.41s
sys     3m 7.22s

time test.sh
real    3m 44.24s
user    0m 32.31s
sys     3m 7.60s

After the patch:

time test.sh
real    3m 41.32s
user    0m 28.92s
sys     3m 8.08s

time test.sh
real    3m 39.92s
user    0m 30.20s
sys     3m 5.56s

So any performance differences seems to be in the error margin.

Arnd Bergmann a829ae57f8 ARM: s3c64xx: use new adc/touchscreen driver
The old ADC and touchscreen drivers are not compatible with
multiplatform support, but we can use the exynos-adc driver
as a replacement.

This changes the common device creation functions for s3c64xx
(but not s3c24xx for now) to use the new driver. To do this,
we have to pass the interrupt resources in the opposite order
and pass the platform data in the adc device node.

Arnd Bergmann df0cc2d1e1 ASoC: samsung/smartq: use dynamic registration
As a prerequisite for moving s3c64xx into multiplatform configurations,
we need to change the smartq audio driver to stop using hardcoded
gpio numbers from the header file, and instead pass the gpio data
through platform_data.

In order to do that, we also move the code to use module_platform_driver
and register the platform device using platform_device_register_simple
and register the gpios through the gpiod API.

Linus Torvalds f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform

Linus Walleij 41c3548e6d ARM: s3c64xx: get rid of custom <mach/gpio.h>
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.

Kukjin Kim b024043b6d ARM: 7245/1: S3C64XX: introduce arch/arm/mach-s3c64xx/common.[ch]
This patch introduces common.[ch] which are used only in the
arch/arm/mach-s3c64xx/ directory. The common.c file merges
the cpu.c, irq.c and irq-eint.c which are used commonly on
S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h
and plat/s3c6410.h files.

This fixes a section mismatch found by modpost:

	WARNING: arch/arm/mach-s3c64xx/built-in.o(.data+0x2498): Section mismatch in reference from the variable smartq_backlight_data to the function .init.text:smartq_bl_init()

Maurus Cuelenaere eeda5fcb4f ARM: S3C64XX: Set wifi and iNAND as permanently connected SD devices on SmartQ boards
This patch changes the platform data definitions of the wifi and iNAND chip on
the SmartQ 5 and 7 to indicate that they don't have a CD line available and are
thus hard-wired to the SDHCI data lines.
