201c910bd6 of: Transactional DT support.
Introducing DT transactional support.

A DT transaction is a method which allows one to apply changes
in the live tree, in such a way that either the full set of changes
take effect, or the state of the tree can be rolled-back to the
state it was before it was attempted. An applied transaction
can be rolled-back at any time.

Documentation is in
	Documentation/devicetree/changesets.txt

126ae9adc1 crypto: ccp - Base AXI DMA cache settings on device tree
The default cache operations for ARM64 were changed during 3.15.
To use coherent operations a "dma-coherent" device tree property
is required.  If that property is not present in the device tree
node then the non-coherent operations are assigned for the device.

Add support to the ccp driver to assign the AXI DMA cache settings
based on whether the "dma-coherent" property is present in the device
node.  If present, use settings that work with the caches.  If not
present, use settings that do not look at the caches.

223f93ed7e ARM: tegra: device tree changes for 3.17

 - HDA support for Tegra124 and Venice2
 - Display on Medcom Wide and Roth
 - GK20A support on Tegra124
 - XUSB pad controller for Tegra124 and Jetson TK1
 - Various cleanups
 
 This pulls in the for-3.17/fuse-move, for-3.17/dt-cros-ec-kbd and
 for-3.17/xusb-padctl branches to resolve dependencies.
 
 Note that the Apalis T30 support has a runtime dependency on the
 for-3.17/pcie-regulators branch, so they should preferably be applied
 in that order. I didn't merge that branch into this because Apalis T30
 support is new, therefore can't regress, and because the dependency
 exists only at runtime.

23e892929e ARM: tegra: move fuse code out of arch/arm
This branch moves code related to the Tegra fuses out of arch/arm and
 into a centralized location which could be shared with ARM64. It also
 adds support for reading the fuse data through sysfs.
 
 Included is also some preparatory work that moves Tegra-related header
 files from include/linux to include/soc/tegra as suggested by Arnd.
 
 Furthermore the Tegra chip ID is now retrieved using a function rather
 than a variable so that sanity checks can be done. This is convenient
 in subsequent patches that will move some of the code that's currently
 called from Tegra machine setup into regular initcalls so that it can
 be reused on 64-bit ARM. The sanity checks help with verifying that no
 code tries to obtain the Tegra chip ID before the underlying driver is
 properly initialized.

128bb95deb Input: add driver for Microchip's CAP1106
This patch adds a driver for Microchips CAP1106, an I2C driven, 6-channel
capacitive touch sensor.

For now, only the capacitive buttons are supported, and no specific
settings that can be tweaked for individual channels, except for the
device-wide sensitivity gain. The defaults seem to work just fine out of
the box, so I'll leave configurable parameters for someone who's in need
of them and who can actually measure the impact. All registers are
prepared, however. Many of them are just not used for now.

The implementation does not make any attempt to be compatible to platform
data driven boards, but fully depends on CONFIG_OF.

Power management functions are also left for volounteers with the ability
to actually test them.

6d0a067ff0 ARM: tegra: initial support for apalis t30
This patch adds the device tree to support Toradex Apalis T30, a
computer on module which can be used on different carrier boards.

The module consists of a Tegra 3 SoC, two PMICs, 1 or 2 GB of DDR3L
RAM, eMMC, an LM95245 temperature sensor chip, an i210 resp. i211
gigabit Ethernet controller, an STMPE811 ADC/touch controller as well
as two MCP2515 CAN controllers. Furthermore, there is an SGTL5000 audio
codec which is not yet supported. Anything that is not self contained
on the module is disabled by default.

1bf8cc3d01 cpufreq: cpu0: OPPs can be populated at runtime
OPPs can be populated statically, via DT, or added at run time with
dev_pm_opp_add().

While this driver handles the first case correctly, it would fail to populate
OPPs added at runtime. Because call to of_init_opp_table() would fail as there
are no OPPs in DT and probe will return early.

To fix this, remove error checking and call dev_pm_opp_init_cpufreq_table()
unconditionally.

Update bindings as well.

ee2d8ea1e9 clk: mvebu: extend clk-cpu for dynamic frequency scaling
This commit extends the existing clk-cpu driver used on Marvell Armada
XP platforms to support the dynamic frequency scaling of the CPU
clock. Non-dynamic frequency change was already supported (and used
before secondary CPUs are started), but the dynamic frequency change
requires a completely different procedure.

In order to achieve this, the clk_cpu_set_rate() function is reworked
to handle two separate cases:

 - The case where the clock is enabled, which is the new dynamic
   frequency change code, implemented in clk_cpu_on_set_rate(). This
   part will be used for cpufreq activities.

 - The case where the clock is disabled, which is the existing
   frequency change code, moved in clk_cpu_off_set_rate(). This part
   is already used to set the clock frequency of the secondary CPUs
   before starting them.

In order to implement the dynamic frequency change function, we need
to access the PMU DFS registers, which are outside the currently
mapped "Clock Complex" registers, so a new area of registers is now
mapped. This affects the Device Tree binding, but we are careful to do
it in a backward-compatible way (by allowing the second pair of
registers to be non-existent, and in this case, ensuring
clk_cpu_on_set_rate() returns an error).

Note that technically speaking, the clk_cpu_on_set_rate() does not do
the entire procedure needed to change the frequency dynamically, as it
involves touching a number of PMSU registers. This is done through a
clock notifier registered by the PMSU driver in followup commits.

d7f3ec2b69 ARM: mvebu: add CA9 MPcore SoC Controller node
The CA9 MPcore SoC Control block is a set of registers that allows to
configure certain internal aspects of the core blocks of the SoC
(Cortex-A9, L2 cache controller, etc.). In most cases, the default
values are fine so they aren't many reasons to touch those registers,
but there is one exception: to support cpuidle on Armada 38x, we need
to modify the value of the CA9 MPcore Reset Control register.

Therefore, this commit adds a new Device Tree binding for this
hardware block, and uses this new binding for the Armada 38x Device
Tree file.

9a2c1c3b91 pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodes
One of remaining limitations of current pinctrl-samsung driver was
the inability to parse multiple pinmux/pinconf group nodes grouped
inside a single device tree node. It made defining groups of pins for
single purpose, but with different parameters very inconvenient.

This patch implements Tegra-like support for grouping multiple pinctrl
groups inside one device tree node, by completely changing the way
pin groups and functions are parsed from device tree. The code creating
pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while
the initial creation of groups and functions has been completely
rewritten with following assumptions:
 - each group consists of just one pin and does not depend on data
   from device tree,
 - each function is represented by a device tree child node of the
   pin controller, which in turn can contain multiple child nodes
   for pins that need to have different configuration values.

Device Tree bindings are fully backwards compatible. New functionality
can be used by defining a new pinctrl group consisting of several child
nodes, as on following example:

	sd4_bus8: sd4-bus-width8 {
		part-1 {
			samsung,pins = "gpk0-3", "gpk0-4",
					"gpk0-5", "gpk0-6";
			samsung,pin-function = <3>;
			samsung,pin-pud = <3>;
			samsung,pin-drv = <3>;
		};
		part-2 {
			samsung,pins = "gpk1-3", "gpk1-4",
					"gpk1-5", "gpk1-6";
			samsung,pin-function = <4>;
			samsung,pin-pud = <4>;
			samsung,pin-drv = <3>;
		};
	};

Tested on Exynos4210-Trats board and a custom Exynos4212-based one.

Upcoming Rockchip SoCs have additional quirks to handle. Currently they would
be handled by giving the bank a special compatible property. But the nature
of the new quirks would require a lot of them. Also as we want to move to the
separate dw_gpio driver in the future, these bank-definitions should be
extended at all.

Describing the bank quirks this way also enables us to deprecate the special
bank compatible string for bank0 on rk3188 and simplify the handling code.

c760569d0e ARM: EXYNOS: Add support for clock handling in power domain
While powering on/off a local powerdomain in exynos5 chipsets, the
input clocks to each device gets modified. This behaviour is based
on the SYSCLK_SYS_PWR_REG registers.
E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC
                             (aclk333) gets modified to oscclk
                            = 0x1, no change in clocks.
The recommended value of SYSCLK_SYS_PWR_REG before power gating any
domain is 0x0. So we must also restore the clocks while powering on
a domain everytime.

This patch adds the framework for getting the required mux and parent
clocks through a power domain device node. With this patch, while
powering off a domain, parent is set to oscclk and while powering back
on, its re-set to the correct parent which is as per the recommended
pd on/off sequence.

The primary purpose of this patch is to add information about (now
required) aliases of UART ports. However the documentation currently is
heavily outdated and so this patch also takes care of this.

883df42abf USB: tegra: Add resets & has-utmi-pad-registers flag to the PHY binding
When Tegra was converted to use the standard reset bindings, the PHY was
forgotten, probably because all the resetting of the USB blocks were
done in the EHCI driver. What also went unnoticed is that resetting the
1st on-chip USB module also wipes some of the UTMI pad configuration
registers that are also used by the other USB blocks. So this fact needs
to be described in the device tree, and the driver modified not to reset
the 1st module at inappropriate times.

In order to stay compatible with old device trees, the USB drivers will
still function without these properties but with the old,
potentially buggy behaviour.

455e5cd6f7 mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335x
The am335x can't detect pending cirq in PM runtime suspend.
This patch reconfigures dat1 as a GPIO before going to suspend.
SDIO interrupts are detected with the GPIO, the GPIO will only wake
the module from suspend, SDIO irq detection will still happen through the
IP block.

2cd3a2a546 mmc: omap_hsmmc: Enable SDIO interrupt
There have been various patches floating around for enabling
the SDIO IRQ for hsmmc, but none of them ever got merged.

Probably the reason for not merging the SDIO interrupt patches
has been the lack of wake-up path for SDIO on some omaps that
has also needed remuxing the SDIO DAT1 line to a GPIO making
the patches complex.

This patch adds the minimal SDIO IRQ support to hsmmc for
omaps that do have the wake-up path. For those omaps, the
DAT1 line need to have the wake-up enable bit set, and the
wake-up interrupt is the same as for the MMC controller.

This patch has been tested on am3730 es1.2 with mwifiex
connected to MMC3 with mwifiex waking to Ethernet traffic
from off-idle mode. Note that for omaps that do not have
the SDIO wake-up path, this patch will not work for idle
modes and further patches for remuxing DAT1 to GPIO are
needed.

Based on earlier patches [1][2] by David Vrabel
<david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com>

For now, only support SDIO interrupt if we are booted with
a separate wake-irq configued via device tree. This is
because omaps need the wake-irq for idle states, and some
omaps need special quirks. And we don't want to add new
legacy mux platform init code callbacks any longer as we
are moving to DT based booting anyways.

To use it, you need to specify the wake-irq using the
interrupts-extended property.

44680eedf9 iommu/arm-smmu: remove support for chained SMMUs
The ARM SMMU driver has supported chained SMMUs (i.e. SMMUs connected
back-to-back in series) via the smmu-parent property in device tree.
This was in anticipation of somebody building such a configuration,
however that seems not to be the case.

This patch removes the unused chained SMMU hack from the driver. We can
consider adding it back later if somebody decided they need it, but for
the time being it's just pointless mess that we're carrying in mainline.

Removal of the feature also makes migration to the generic IOMMU bindings
easier.

Palmas class of devices can provide 32K clock(s) to be used by other devices
on the board. Depending on the actual device the provided clocks can be:
CLK32K_KG and CLK32K_KGAUDIO
or only one:
CLK32K_KG (TPS659039 for example)

Use separate compatible flags for the two 32K clock.
A system which needs or have only one of the 32k clock from
Palmas will need to add node(s) for each clock as separate section
in the dts file.
The two compatible property is:
"ti,palmas-clk32kg" for clk32kg clock
"ti,palmas-clk32kgaudio" for clk32kgaudio clock

Apart from the register control of the clocks - which is done via
the clock API there is a posibility to enable the external sleep
control. In this way the clock can be enabled/disabled on demand by the
user of the clock.

To: Tejun Heo <tj@kernel.org>,linux-ide@vger.kernel.org

The Freescale i.MX SATA controller mostly conforms to the AHCI
interface, but there are some special extensions at integration level
like clocks settings and hardware parameters.

Let's create a separate bindings doc for imx sata controller, so that
more imx specific properties can be added later without messing up the
generic ahci-platform bindings.

4db8e6d20c irqchip: or1k-pic: Migrate from arch/openrisc/
In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.

All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c

In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt
controller that is present in the or1200 OpenRISC cpu
implementation.

d360892d37 irqchip: crossbar: Allow for quirky hardware with direct hardwiring of GIC
On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10, 131,
132, 133 are direct wired to hardware blocks bypassing crossbar.
This quirky implementation is *NOT* supposed to be the expectation
of crossbar hardware usage. However, these are already marked in our
description of the hardware with SKIP and RESERVED where appropriate.

Unfortunately, we need to be able to refer to these hardwired IRQs.
So, to request these, crossbar driver can use the existing information
from it's table that these SKIP/RESERVED maps are direct wired sources
and generic allocation/programming of crossbar should be avoided.

a35057d1dc irqchip: crossbar: Initialise the crossbar with a safe value
Since crossbar is s/w configurable, the initial settings of the
crossbar cannot be assumed to be sane. This implies that:
a) On initialization all un-reserved crossbars must be initialized to
   a known 'safe' value.
b) When unmapping the interrupt, the safe value must be written to
   ensure that the crossbar mapping matches with interrupt controller
   usage.

So provide a safe value in the dt data to map if
'0' is not safe for the platform and use it during init and unmap

While at this, fix the below checkpatch warning.

98ea2dba65 ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache
When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
controller and the Cortex-A9.

To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.

Note that technically speaking, a fully coherent system wouldn't
require any of the other .outer_cache operations. However, in
practice, when booting secondary CPUs, these are not yet coherent, and
therefore a set of cache maintenance operations are necessary at this
point. This explains why we keep the other .outer_cache operations and
only ->sync is disabled.

While in theory any write to a PL310 register could cause the
deadlock, in practice, disabling ->sync is sufficient to workaround
the deadlock, since the other cache maintenance operations are only
used in very specific situations.

Contrary to previous versions of this patch, this new version does not
simply NULL-ify the ->sync member, because the l2c_init_data
structures are now 'const' and therefore cannot be modified, which is
a good thing. Therefore, this patch introduces a separate
l2c_init_data instance, called of_l2c310_coherent_data.

d9288d0ba1 ASoC: rsnd: SSI + DMA can select BUSIF
Sound data needs to be sent to R-Car sound SSI when playback.
But, there are 2 interfaces for it.
1st is SSITDR/SSIRDR which are mapped on SSI.
2nd is SSIn_BUSIF which are mapped on SSIU.

2nd SSIn_BUSIF is used when DMA transfer,
and it is always used if sound data came from via SRC.
But, we can use it when SSI+DMA case too.
(Current driver is assuming 1st SSITDR/SSIRDR for it)

2nd SSIn_BUSIF can be used as FIFO.
This is very helpful/useful for SSI+DMA.

But DMA address / DMA ID are not same between 1st/2nd cases.

Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Arnd Bergmann:
 "A new set of bug fixes for 3.16, containing patches for seven
  platforms:

  at91:
    - drivers/misc fix for Kconfig PWM symbol
    - correction of several values in DT after conversion to CCF
    - fix at91sam9261/at91sam9261ek mistake in slow crystal vs. slow RC osc

  imx:
    - Use GPIO for card CD/WP on imx51-babbage and eukrea-mbimxsd51,
      because controller base CD/WP is not working in esdhc driver due to
      runtime PM support
    - A couple of random ventana gw5xxx board fixes
    - Add IMX_IPUV3_CORE back to defconfig, which gets lost when moving
      IPUv3 driver out of staging tree
    - Fix enet/fec clock selection on imx6sl
    - Fix display node on imx53-m53evk board
    - A couple of Cubox-i updates from Russell, which were omitted from
      the merge window due to dependency

  integrator:
    - fix an OF-related regression against 3.15

  mvebu:
    - mvebu (v7)
       - Fix broken SoC ID detection
       - Select ARM_CPU_SUSPEND for v7
       - Remove armada38x compatible string (no users yet)
       - Enable Dove SoC in mvebu_v7_defconfig
    - kirkwood
       - Fix phy-connection-type on GuruPlug board

  qcom:
    - enable gsbi driver in defconfig
    - fix section mismatch warning in serial driver

  samsung:
    - use WFI macro in platform_do_lowpower because exynos cpuhotplug
      includes a hardcoded WFI instruction and it causes compile error
      in Thumb-2 mode.
    - fix GIC reg sizes for exynos4 SoCs
    - remove reset timer counter value during boot and resume for mct
      to fix a big jump in printk timestamps
    - fix pm code to check cortex-A9 for another exynos SoCs
    - don't rely on firmware's secondary_cpu_start for mcpm

  sti:
    - Ethernet clocks were wrongly defined for STiH415/416 platforms
    - STiH416 B2020 revision E DTS file name contained uppercase, change to
      lowercase"

8b6f5e0f19 hwmon: (ntc_thermistor) Use the manufacturer name properly
Murata Manufacturing Co., Ltd is the vendor for
NTC (Negative Temperature coefficient) based Thermistors.
But, the driver extensively uses "NTC" as the vendor name.

This patch corrects the vendor name also updates the
compatibility strings according to the vendor-prefix.txt

Note: Drivers continue to support the previous compatible strings
but further addition of these compatible strings in device tree
is deprecated.
