Haojian Zhuang ef5e3eef6b gpio: use pinctrl device name for add range
gpiochip_add_pin_range() needs pinctrl device name as parameter.
Currently the parameter is pinctrl description name. So fix it.

Haojian Zhuang d6e99abb42 pinctrl: core: get devname from pinctrl_dev
Add new function to get devname from pinctrl_dev. pinctrl_dev_get_name()
can only get pinctrl description name. If we want to use gpio driver to
find pinctrl device node, we need to fetch the pinctrl device name.

Lee Jones 32e67eee67 pinctrl: nomadik: Allow prcm_base to be extracted from Device Tree
The Nomadik Pinctrl driver requires access to some PRCMU registers
in order to run with full functionality. When Device Tree is
disabled the required PRCMU base address is passed in via platform
data, so in order for Device Tree booting to be as functional, we
need a similar mechanism to fetch it from Device Tree.

The new semantics goes like this: Parse the Device Tree and look
for the PRCMU node using a provided Phandle. Obtain the ioremaped
address from that node. If one was supplied via platform data
over-write it with anything found in Device Tree. Fail if either
the prcm_base can't be found if we're running on anything other
than an STN8815 ASIC.

Lee Jones 8979cfef26 ARM: ux500: Provide a link from AB8500 Pinctrl to the PRCMU
The AB8500 Pinctrl driver uses PRCMU register addresses to
control Pinctrl related functions. For this to happen, the
Pinctrl driver needs the PRCMU base to work from. We can do
that using standard Open Firmware (of_*) function calls, but
first we need a mechanism to gain access to the PRCMU
device node. We're going to use a Phandle in this case.

Pritesh Raithatha b6ae7a2653 pinctrl: tegra114: add pinctrl driver for NVIDIA's Tegra114 SoC
This adds a driver for the Tegra114 pinmux, and required
parameterization data for Tegra114.

The driver uses the common Tegra pincontrol driver utility
functions to implement the majority of the driver.

This driver is not compatible with the earlier NVIDIA's SoCs,
hence add new compatibile as "nvidia,tegra114-pinmux".

Originally written by Pritesh.

	- remove non-require tables.

Pritesh Raithatha 348d1bf75c pinctrl: tegra: add support for rcv-sel and drive type
NVIDIA's Tegra114 added two more configuration parameter in pinmux i.e.
rcv-sel and drive type.

rcv-sel: Select between High and Normal VIL/VIH receivers.
	RCVR_SEL=1: High VIL/VIH
	RCVR_SEL=0: Normal VIL/VIH

drv_type: Ouptput drive type:
	33-50 ohm driver: 0x1
	66-100ohm driver: 0x0

Add support of these parameters to be configure from DTS file.

Tegra20 and Tegra30 does not support this configuration and hence initialize their
pinmux structure with reg = -1.

Originally written by Pritesh Raithatha.
Changes by ldewangan:
	- remove drvtype_width as it is always 2.
	- Better describe the change.

Linus Walleij 483f33f63c pinctrl: add pinconf-generic defines for output
This adds a definition of a generic output configuration
for a certain pin when using the generic pin configuration
library. Whereas driving pins low/high is usually a GPIO
business, you may want to set up pins into a default state
using hogs, and never touch them again. This helps out
with that scenario.

Linus Walleij 89216494ae pinctrl: skip deferral of hogs
Up until now, as hogs were always taken at the end of the
pin control device registration, it didn't cause any problem.
But when starting to hog pins from the device core it will
cause deferral of the pin controller device itself since the
default pin fetch is done *before* the device probes, so
let's fix this annoyance (which is also aesthetically ugly).

Also take some care to make sure that if any one map entry
results in a deferral rather than a failure, then that
deferral will take precedence.

  - A set of fixes for Samsung Exynos, fixing default bootargs and some

  - A set of OMAP changes including PM fixes and a few sparse warning

 All in all a bit more positive code delta than we'd ideally want to see

Rob Herring 0b3455a71e ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem

of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.

So I add dma_buf_put() for imported gem come from its own gem into each drivers

count is increased if importing gem exported from gem of same driver.

Summary:
- change exynos file license
  . Most of exynos files had been copied from some randome
    file and not updated correctly(wrong company name used).
    This was our mistakes so chagnes it correctly. For this,
    I'm not sure that this patch should go to -fix or -next.
    So please give me any comment if there is any problem.
- consider buffer allocation without iommu
  . Without iommu, dma_alloc_attrs function allocates some
    memory region and returns cpu address so this patch makes
    the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
  . to avoid the duplication of same code, use
    exynos_drm_crtc_finish_pageflip function commonly instead
    of each one.
- fix fimd resume issue.
  . when fimd was turned off by suspend, there was one issue that
    the fimd wasn't turned on by resume so fix it chaing resume
    condition.

Pantelis Antoniou 6adba67eb0 ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs array
The IRQ array must be terminated by -1 and not by -1+OMAP_INTC_START
This led to having a resource list of 100s of IRQs.

Looks like this was caused by commit a2cfc509 (ARM: OMAP3+: hwmod: Add
AM33XX HWMOD data) that probably had some search and replace updates
done for the patch for sparse irq support.

The new use of ESTALE in namei.h can cause compile failures on ARM with
certain configurations due to lack of errno.h.

Alex Elder 36a25de233 sctp: fix Kconfig bug in default cookie hmac selection
Commit 0d0863b020 ("sctp: Change defaults on cookie hmac selection")
added a "choice" to the sctp Kconfig file.  It introduced a bug which
led to an infinite loop when while running "make oldconfig".

The problem is that the wrong symbol was defined as the default value
for the choice.  Using the correct value gets rid of the infinite loop.

Note:  if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input
config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present
in the generated config file.
