be8e58d93f Revert "[media] Add device tree support to adp1653 flash driver"
As requested by Sakari:

	"The driver changes are still being reviewed.
	 It's been proposed that the max-microamp property be renamed."

So, as the DT bindings are not agreed upstream yet, let's revert
it.

Requested-by: Sakari Ailus <sakari.ailus@iki.fi>

82740b9ac2 NFC: 4.1 pull request
This is the NFC pull request for 4.1.
 
 This is a shorter one than usual, as the Intel Field Peak NFC
 driver could not make it in time.
 
 We have:
 
 - A new driver for NXP NCI based chipsets, like e.g. the NPC100 or
   the PN7150. It currently only supports an i2c physical layer, but
   could easily be extended to work on top of e.g. SPI.
   This driver also includes support for user space triggered firmware
   updates.
 
 - A few minor st21nfc[ab] fixes, cleanups, and comments improvements.
 
 - A pn533 error return fix.
 
 - A few NFC related logs formatting cleanups.

8c2c8c03cd spi: img-spfi: Control CS lines with GPIO
When the CONTINUE bit is set, the interrupt status we are polling to
identify if a transaction has finished can be sporadic.  Even though
the transfer has finished, the interrupt status may erroneously
indicate that there is still data in the FIFO.  This behaviour causes
random timeouts in large PIO transfers.

Instead of using the CONTINUE bit to control the CS lines, use the SPI
core's CS GPIO handling.  Also, now that the CONTINUE bit is not being
used, we can poll for the ALLDONE interrupt to indicate transfer
completion.

6cff8d60aa platform: x86: dell-laptop: Add support for keyboard backlight
This patch adds the support for the configuration of the keyboard
backlight on supported Dell laptops.

With this patch it is possible to set:
* keyboard backlight level
* timeout after which the backlight will be automatically turned off
* input activity triggers (keyboard, touchpad, mouse) that enable the backlight
* ambient light settings

The settings are exposed via /sys/class/leds/dell::kbd_backlight/

The code is based on the newly released documentation by Dell in the
libsmbios project.

a08aad54be drm/panel: Changes for v4.1-rc1
This set of changes adds support for a whole bunch of new panels, mostly
 simple ones. There's now also support for panels to provide display
 timings rather than fixed modes, which should allow panels to work with
 a larger number of display drivers. Eventually drivers should migrate to
 this new interface and the fixed modes removed from panels.
 
 There are also a couple of sparse fixes for the PS8622 and PS8625 bridge
 drivers.

cec656501f pinctrl: Document "function" + "pins" pinmux binding
Currently the "function" + "groups" combination is the only documented
format for pinmux nodes, although many drivers use "function" + "pins".
Update the generic pinctrl binding to include the "function" + "pins"
combination as well.

Pull networking fixes from David Miller:

 1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
    previously SACK'd, from Neal Cardwell.

 2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
    from Cong WANG.

 3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
    from Cong WANG.

 4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.

 5) When we encapsulate for a tunnel device, skb->sk still points to the
    user socket.  So this leads to cases where we retraverse the
    ipv4/ipv6 output path with skb->sk being of some other address
    family (f.e. AF_PACKET).  This can cause things to crash since the
    ipv4 output path is dereferencing an AF_PACKET socket as if it were
    an ipv4 one.

    The short term fix for 'net' and -stable is to elide these socket
    checks once we've entered an encapsulation sequence by testing
    xmit_recursion.

    Longer term we have a better solution wherein we pass the tunnel's
    socket down through the output paths, but that is way too invasive
    for 'net' and -stable.

    From Hannes Frederic Sowa.

 6) l2tp_init() failure path forgets to unregister per-net ops, from
    Cong WANG.

303038135a net: dsa: fix filling routing table from OF description
According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.

However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.

This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.

To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.

This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

8ff16cf77c Documentation: devicetree: m25p80: add "nor-jedec" binding
Almost all flash that are "compatible" with m25p80 support the JEDEC
READ ID opcode (0x9F), and in fact, that is often the only thing that is
used to differentiate them. Let's add a compatible string that
represents this lowest common denominator of compatibility.

Device trees can still specify manufacturer/device names in addition,
but (until some reason is found to differentiate between them through
device tree) software will likely want to bind just against the generic
name, and avoid unnecessarily growing its device ID binding tables.

This is related to the work of commit a5b7616c55 ("mtd:
m25p80,spi-nor: Fix module aliases for m25p80"), which showed that
maintaining these device tables as stable device-tree/modalias binding
tables is not a worthwhile burden for mostly-comptatible flash.

At the same time, let's update the binding doc to point to the
m25p_ids[] ID list instead of spi_nor_ids[]. The former can be used for
device tree bindings, but the latter cannot. In the future, we should
pare down the m25p_ids[] list to only those IDs which are actually used
in device trees.

efc98f7762 ARM: tegra: Device tree changes for v4.1-rc1
A bunch of changes to improve support on the Nyan Big (Acer Chromebook
 13). These enable the trackpad and make the WiFi card work. Changes to
 the userspace-exposed name of the soundcard are required for a better
 audio experience.
 
 Support for Nyan Blaze (HP Chromebook 14) is added. It is very similar
 to Nyan Big and therefore can enjoys many of the above improvements.
 
 Since the EMC driver can now be used to scale the frequency at which
 external memory is clocked, corresponding EMC frequency tables are added
 for Jetson TK1 and the Nyan boards.
 
 The Jetson TK1, Beaver and Nyan boards now also use generated pinmux
 data, which makes it easier to keep it in sync with the data provided by
 syseng.

ee327179b9 Wireless and omap changes to make wl12xx driver to use device tree
data instead of platform data from Eliad Peller <eliad@wizery.com>:
 
 - Add device-tree support to the wlcore (wl12xx/wl18xx) driver.
 
 - Update the current users to use the bindings instead of pdata-quirks.
 
 - Finally, remove the deprecated wl12xx_platform_data struct
 
 Note that da850 board file code that still uses the platform data,
 but we have da850.dtsi that can be used instead. So it was decided
 that we should try to remove the wl12xx support from the da850
 board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
 the last patch in the series, the last patch can be simply reverted
 if needed.
 
 As this series touches quite a bit of arch code, it was suggested
 by Kalle Valo <kvalo@codeaurora.org> that the whole series should
 be merged via the arm-soc tree.

78cac48c04 x86/mm/KASLR: Propagate KASLR status to kernel proper
Commit:

  e2b32e6785 ("x86, kaslr: randomize module base load address")

made module base address randomization unconditional and didn't regard
disabled KKASLR due to CONFIG_HIBERNATION and command line option
"nokaslr". For more info see (now reverted) commit:

  f47233c2d3 ("x86/mm/ASLR: Propagate base load address calculation")

In order to propagate KASLR status to kernel proper, we need a single bit
in boot_params.hdr.loadflags and we've chosen bit 1 thus leaving the
top-down allocated bits for bits supposed to be used by the bootloader.

cc7d2dfb75 [media] v4l2_plane_pix_format: use __u32 bytesperline instead of __u16
While running v4l2-compliance tests on vivid I suddenly got errors due to
a call to vmalloc_user with size 0 from vb2.

Digging deeper into the cause I discovered that this was due to the fact that
struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32.

The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32
bit pixelformat.

So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And
bytesperline * height is suddenly 0 as well. While the vivid driver may be
a virtual driver, it is to be expected that this limit will be hit for real
hardware as well in the near future: 8k deep-color video will already reach
it.

The solution is to change the type to __u32. The only drivers besides vivid
that use the multiplanar API are little-endian ARM and SH platforms (exynos,
ti-vpe, vsp1), so this is safe.

2ddb77bb11 [media] DocBook v4l: update bytesperline handling
The documentation says that the bytesperline field in v4l2_pix_format refers
to the largest plane in the case of planar formats (i.e. multiple planes
stores in a single buffer).

For almost all planar formats the first plane is also the largest (or equal)
plane, except for two formats: V4L2_PIX_FMT_NV24/NV42. For this YUV 4:4:4
format the second chroma plane is twice the size of the first luma plane.

Looking at the very few drivers that support this format the bytesperline
value that they report is actually that of the first plane and not that
of the largest plane.

Rather than fixing the drivers it makes more sense to update the documentation
since it is very difficult to use the largest plane for this. You would have
to check what the format is in order to know to which plane bytesperline
belongs, which makes calculations much more difficult.

This patch updates the documentation accordingly.

38e42f1216 ARM: 8335/1: Documentation: DT bindings: Tegra AHB: document the legacy base address
Documentation: DT bindings: Tegra AHB: require the legacy base address for existing chips

Per Stephen Warren, note in the Tegra AHB DT binding documentation
that we specifically deprecate any attempt to use the IP block's
actual hardware base address, and advocate the use of the legacy
"off-by-four" address in the 'regs' property, for Tegra chips with
existing upstream Linux DT files that include a Tegra AHB node.  This
patch updates the documentation accordingly.

Changing the existing kernel DT data isn't under consideration because
Linux kernel DT data policy is to preserve compatibility between newer
DT data files and older kernels.  However, this additional step of
changing the documentation should discourage others from sending
kernel patches to try to change the legacy kernel DT data.
Furthermore, for out-of-tree software (such as bootloaders or other
operating systems) that may rely on Linux kernel DT binding
documentation as an ABI (but not the Linux kernel DT data itself),
such a change may allow future convergence with the Linux kernel DT
data without additional code changes.

the kernel executes:

		mmc_switch(card, EXT_CSD_CMD_SET_NORMAL,
 				EXT_CSD_HPI_MGMT, 1,
 				card->ext_csd.generic_cmd6_time);

There seems to be no way to reliable identify eMMC-s which have a broken
hpi implementation, but at least for eMMC's which are soldered onto a board
we can work around this by specifying that hpi is broken in devicetree.

several things wrong in the DT documentation: -

1) Compatible string doesn't match the driver code
2) pwr-rst reset isn't documented (but exists in the driver)
3) some whitespace issues (spaces not tabs)

Also add in a stih407 family example into the doc.

As an alternative to the "clock-frequency" property, allow the GIC
timer operating clock to be specified in the device-tree instead.
This is useful on systems which use common clock or where the GIC
is not fixed to a particular frequency and is instead, for example,
derived from the CPU clock.

5f7f0317ed IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllers
This is the main peripheral IRQ controller on the BCM7xxx MIPS chips;
it has the following characteristics:

 - 64 to 160+ level IRQs
 - Atomic set/clear registers
 - Reasonably predictable register layout (N status words, then N
   mask status words, then N mask set words, then N mask clear words)
 - SMP affinity supported on most systems
 - Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3

This driver registers one IRQ domain and one IRQ chip to cover all
instances of the block.  Up to 4 instances of the block may appear, as
it supports 4-way IRQ affinity on BCM7435.

The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC
is used instead.  So this driver is primarily intended for MIPS STB chips.

ca40f1b23d IRQCHIP: bcm7120-l2: Split STB-specific logic into its own function
The BCM7xxx instances of this block (listed in the register manual as
simply "IRQ0") all have the following items in common:

 - brcm,int-map-mask: for routing different bits in the L2 to different
   parent IRQs

 - brcm,int-fwd-mask: for hardwiring certain IRQs to bypass the L2 and
   use dedicated L1 lines

 - one enable/status pair (32 bits only)

Much of the driver code can be shared with BCM3380-style controllers, but
in order to do this cleanly, let's split out the BCM7xxx-specific logic
first.

Linux code using this type to various vendors.

Wire this e820 table type up to export platform devices for the
pmem driver so that we can use it in Linux.

a5581ef4c2 can: introduce new raw socket option to join the given CAN filters
The CAN_RAW socket can set multiple CAN identifier specific filters that lead
to multiple filters in the af_can.c filter processing. These filters are
indenpendent from each other which leads to logical OR'ed filters when applied.

This socket option joines the given CAN filters in the way that only CAN frames
are passed to user space that matched *all* given CAN filters. The semantic for
the applied filters is therefore changed to a logical AND.

This is useful especially when the filterset is a combination of filters where
the CAN_INV_FILTER flag is set in order to notch single CAN IDs or CAN ID
ranges from the incoming traffic.

As the raw_rcv() function is executed from NET_RX softirq the introduced
variables are implemented as per-CPU variables to avoid extensive locking at
CAN frame reception time.

816c7667ea KVM: s390: migrate vcpu interrupt state
This patch adds support to migrate vcpu interrupts. Two new vcpu ioctls
are added which get/set the complete status of pending interrupts in one
go. The ioctls are marked as available with the new capability
KVM_CAP_S390_IRQ_STATE.

We can not use a ONEREG, as the number of pending local interrupts is not
constant and depends on the number of CPUs.

To retrieve the interrupt state we add an ioctl KVM_S390_GET_IRQ_STATE.
Its input parameter is a pointer to a struct kvm_s390_irq_state which
has a buffer and length.  For all currently pending interrupts, we copy
a struct kvm_s390_irq into the buffer and pass it to userspace.

To store interrupt state into a buffer provided by userspace, we add an
ioctl KVM_S390_SET_IRQ_STATE. It passes a struct kvm_s390_irq_state into
the kernel and injects all interrupts contained in the buffer.

751e2676ee drm/imx: imx-ldb: add drm_panel support
This patch allows to optionally attach the lvds-channel to a panel
supported by a drm_panel driver using of-graph bindings, instead of
supplying the modes via display-timings in the device tree.

This depends on of_graph_get_port_by_id and uses the OF graph to
link the optional DRM panel to the LDB lvds-channel. The output
port number is 1 on devices without the 4-port input multiplexer
(i.MX5) and 4 on devices with the mux (i.MX6).

Before:

	ldb {
		...

		lvds-channel@0 {
			...

			display-timings {
				native-timing = <&timing1>;
				timing1: etm0700g0dh6 {
					hactive = <800>;
					vactive = <480>;
					clock-frequency = <33260000>;
					hsync-len = <128>;
					hback-porch = <88>;
					hfront-porch = <40>;
					vsync-len = <2>;
					vback-porch = <33>;
					vfront-porch = <10>;
					hsync-active = <0>;
					vsync-active = <0>;
					...
				};
			};
			...
		};
	};

After:
	ldb {
		...

		lvds-channel@0 {
			...

			port@4 {
				reg = <4>;

				lvds_out: endpoint {
					remote_endpoint = <&panel_in>;
				};
			};
		};
	};

	panel {
		compatible = "edt,etm0700g0dh6", "simple-panel";
		...

		port {
			panel_in: endpoint {
				remote-endpoint = <&lvds_out>;

f4f4673b75 iio: add support for hardware fifo
Some devices have hardware buffers that can store a number of samples
for later consumption. Hardware usually provides interrupts to notify
the processor when the FIFO is full or when it has reached a certain
watermark level. This helps with reducing the number of interrupts to
the host processor and thus it helps decreasing the power consumption.

This patch enables usage of hardware FIFOs for IIO devices in
conjunction with software device buffers. When the hardware FIFO is
enabled the samples are stored in the hardware FIFO. The samples are
later flushed to the device software buffer when the number of entries
in the hardware FIFO reaches the hardware watermark or when a flush
operation is triggered by the user when doing a non-blocking read
on an empty software device buffer.

In order to implement hardware FIFO support the device drivers must
implement the following new operations: setting and getting the
hardware FIFO watermark level, flushing the hardware FIFO to the
software device buffer. The device must also expose information about
the hardware FIFO such it's minimum and maximum watermark and if
necessary a list of supported watermark values. Finally, the device
driver must activate the hardware FIFO when the device buffer is
enabled, if the current device settings allows it.

The software device buffer watermark is passed by the IIO core to the
device driver as a hint for the hardware FIFO watermark. The device
driver can adjust this value to allow for hardware limitations (such
as capping it to the maximum hardware watermark or adjust it to a
value that is supported by the hardware). It can also disable the
hardware watermark (and implicitly the hardware FIFO) it this value is
below the minimum hardware watermark.

Since a driver may support hardware FIFO only when not in triggered
buffer mode (due to different semantics of hardware FIFO sampling and
triggered sampling) this patch changes the IIO core code to allow
falling back to non-triggered buffered mode if no trigger is enabled.

415f1cb29d ASoC: rsrc-card: add Renesas sampling rate convert sound card support
Renesas sound card has "sampling rate convert" feature which
should be implemented via DPCM.
But, sound card driver point of view, it is difficult to add
this DPCM feature on simple-card driver. Especially, DT binding
support is very difficult.

This patch implements DPCM feature on DT as Renesas specific sound card.
This new driver is copied from current simple-card driver.
Main difference between simple-card and this driver are...
 1. removed unused feature from simple-card
 2. removed driver named prefix from DT property
 3. CPU will be FE, CODEC will be BE with snd-soc-dummy
 4. it supports sampling rate convert via .be_hw_params_fixup
 5. board specific routing is implemented in driver

ioctls when the MSA capability is enabled (exposed in a later patch) and

The MSA vector registers use the same register numbers as the FPU
registers except with a different size (128bits). Since MSA depends on
Status.FR=1, these registers are inaccessible when Status.FR=0. These
registers are returned as a single native endian 128bit value, rather
than least significant half first with each 64-bit half native endian as
the kernel uses internally.

Add Config4 and Config5 co-processor 0 registers, and add capability to
write the Config1, Config3, Config4, and Config5 registers using the KVM
API.

Only supported bits can be written, to minimise the chances of the guest
being given a configuration from e.g. QEMU that is inconsistent with
that being emulated, and as such the handling is in trap_emul.c as it
may need to be different for VZ. Currently the only modification
permitted is to make Config4 and Config5 exist via the M bits, but other
bits will be added for FPU and MSA support in future patches.

Care should be taken by userland not to change bits without fully
handling the possible extra state that may then exist and which the
guest may begin to use and depend on.

772742a6c7 arm-cci: Get rid of secure transactions for PMU driver
Avoid secure transactions while probing the CCI PMU. The
existing code makes use of the Peripheral ID2 (PID2) register
to determine the revision of the CCI400, which requires a
secure transaction. This puts a limitation on the usage of the
driver on systems running non-secure Linux(e.g, ARM64).

Updated the device-tree binding for cci pmu node to add the explicit
revision number for the compatible field.

The supported strings are :
	arm,cci-400-pmu,r0
	arm,cci-400-pmu,r1
	arm,cci-400-pmu - DEPRECATED. See NOTE below

NOTE: If the revision is not mentioned, we need to probe the cci revision,
which could be fatal on a platform running non-secure. We need a reliable way
to know if we can poke the CCI registers at runtime on ARM32. We depend on
'mcpm_is_available()' when it is available. mcpm_is_available() returns true
only when there is a registered driver for mcpm. Otherwise, we assume that we
don't have secure access, and skips probing the revision number(ARM64 case).

The MCPM should figure out if it is safe to access the CCI. Unfortunately
there isn't a reliable way to indicate the same via dtb. This patch doesn't
address/change the current situation. It only deals with the CCI-PMU, leaving
the assumptions about the secure access as it has been, prior to this patch.

This patch adds a new optional device tree entry that can configure this
delay in terms of nanoseconds. The kernel will calculate the
best-fitting amount of parent clock ticks to program the controller with
based on that.

735f00bdf2 ARM64 / ACPI: additions of ACPI documentation for arm64
One more documentation file are also being added:

A section by section review of the ACPI spec (acpi_object_usage.txt)
to note recommendations and prohibitions on the use of the numerous
ACPI tables and objects.  This sets out the current expectations of
the firmware by Linux very explicitly (or as explicitly as I can, for
now).

5590f3196b drivers/core/of: Add symlink to device-tree from devices with an OF node
So I've been annoyed lately with having a bunch of devices such as i2c
eeproms (for use by VPDs, server world !) and other bits and pieces that
I want to be able to identify from userspace, and possibly provide
additional data about from FW.

Basically, it boils down to correlating the sysfs device with the OF
tree device node, so that user space can use device-tree info such as
additional "location" or "label" (or whatever else we can come up with)
propreties to identify a given device, or get some attributes of use
about it, etc...

Now, so far, we've done that in some subsystem in a fairly ad-hoc basis
using "devspec" properties. For example, PCI creates them if it can
correlate the probed device with a DT node. Some powerpc specific busses
do that too.

However, i2c doesn't and it would be nice to have something more generic
since technically any device can have a corresponding device tree node.

This patch adds an "of_node" symlink to devices that have a non-NULL
dev->of_node pointer, the patch is pretty trivial and seems to work just
fine for me.

b10d79f760 ARM64 / ACPI: Introduce early_param "acpi=" to enable/disable ACPI
This implements the following policy to decide whether ACPI should
be used to boot the system:
- acpi=off: ACPI will not be used to boot the system, even if there is
  no alternative available (e.g., device tree is empty)
- acpi=force: only ACPI will be used to boot the system; if that fails,
  there will be no fallback to alternative methods (such as device tree)
- otherwise, ACPI will be used as a fallback if the device tree turns out
  to lack a platform description; the heuristic to decide this is whether
  /chosen is the only node present at depth 1

      and approach taken in this patch are complex.  Basically there is no

 * itg3200 - suspend/resume support
 * mcp320x - add more ADCs to the kconfig to reflect what the driver supports
      (this patch and the bindings got left behind when the support was added

 * mcp3422 - DT bindings.
 * mcp320x - DT bindings
 * ABI docs for event threshold scale attributes, in_magn_offset, proximity
   scan_element and thresh falling/rising values for accelerometers.  All
   elements long in use that have slipped by being explicitly documented.
 * Tidy up the tools previously in drivers/staging/iio/Documentation and move
   them out to /tools/iio. Yet another move that should have happened long ago.
   This time Roberta Dobrescu did the leg work.  Thanks!
 
 Core Cleanups
 * Export userspace IIO headers.  We should have done the appropriate header
   splitting a long time ago. Thanks to Daniel for sorting this out.
 
 * Refactor the registring of attributes for buffers to move all non-custom
   ones to a vector allowing easier additions to the current set in the future.
 
 Driver Cleanups
 * gpiod related cleanups.  Make use of the additional parameter to specify
   	initial direciton to avoid extra code.
 * bmc150 - Various refactorings to reduce code repitition and prepare for
            hardware buffer support.  Some of these cleanups are good even
 	   without the new functionality.
 * kmx61 - direct use of index to an array avoiding a structure element which
           was always the index to an element in an array of that structure.
 * vf610 - avoid incorrect type for return from wait_for_completion_timeout.
 * gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
 * ade7754 - improve error handling including suppressing some build warnings.
 * ade7759 - improve error handling including suppressing some build warnings.
 * hmc5843 - Long line and indentation fixes. Also some constifying of various

 * ad2s1210 - fix wrong printf format string.
 * mxs-lradc - fix wrong printf format string.
 * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
 * periodic rtc trigger - make the frequency type an unsigned int as it
   is always treated as such.
 * jsa1212 - constify struct regmap_config as it is constant.
 * ad7793 - typo in the MODULE_DESCRIPTION
 * mma9551 - check gpiod_to_irq errors.  Note that this doesn't actually cause

If vlan offloading takes place then vlan header is removed from frame
and its contents, both vlan_tci and vlan_proto, is available to user
space via TPACKET interface. However, only vlan_tci can be used in BPF
filters.

This commit introduces a new BPF extension. It makes possible to load
the value of vlan_proto (vlan TPID) to register A. Support for classic
BPF and eBPF is being added, analogous to skb->protocol.

71bbf038ea dt: pmu: extend ARM PMU binding to allow for explicit interrupt affinity
The current ARM PMU binding relies on the PMU interrupts being listed in
CPU logical order, which the device-tree author simply cannot know
anything about.

This patch introduces a new "interrupt-affinity" property, which makes
the relationship between the PMU interrupts and their corresponding
CPU explicit.

Currently 'Playback Volume' is the correct way to express an analogue
volume control. However, this control name has initialisation defaults
applied when using 'alsactl restore' and in some cases this is not
appropriate. An example would be a control that has a selection of
0db and -6dB of gain that is intended to set the fullscale ouput
voltage of a DAC. The TI pcm512x family of DAcs have such a control.
In this case the device/driver reset defaults are preferred.

9a391c7ba7 net: netcp: ethss: enhancement to support NetCP 1.5 ethss
NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.

To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.

For more reading on the details of this peripheral, please refer to the
User Guide available at http://www.ti.com/lit/pdf/spruhz3

21e0e0ddda net: netcp: use separate reg region for individual ethss modules
Ethss has multiple modules within the sub system
 - switch sub system
 - sgmii
 - mdio
 - switch module

NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.

Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

a736775db6 Input: add MT_TOOL_PALM
Currently there are only two "tools" that can be specified by a multi-touch
driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
vendor) and discussing their next-gen devices it seems that it will be
useful to have more tools so that their devices can give the upper layers
of the stack hints as to what is touching the sensor.

In particular they have new experimental firmware that can better
differentiate between palms vs fingertips and would like to plumb a patch
so that we can use their hints in higher-level gesture soft- ware.  The
firmware on the device can reasonably do a better job of palm detection
because it has access to all of the raw sensor readings as opposed to just
the width/pressure/etc that are exposed by the driver.  As such, the
firmware can characterize what a palm looks like in much finer-grained
detail and this change would allow such a device to share its findings with
the kernel.
