53a5fde05d arm64: Use generic Layerscape SoC family naming
Freescale will be a spinning-out a set of ARMv8 based SoCs which
will be based on a similar overall SoC architecture. So, this patch
converts the existing infrastructure in the arm64/dts, arm64/Kconfig
and arm64/configs to use the generic convention ARCH_LAYERSCAPE
in place of the more specific FSL_LS2085A, to save code duplication
later-on.

4db7062c9a ARM: dts: fix gpio-keys wakeup-source property
The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"

However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.

This patch fixes it by making use of "wakeup-source" property.

8ee57b8182 ARM64: dts: vexpress: Use a symlink to vexpress-v2m-rs1.dtsi from arch=arm
Commit 9ccd608070 "arm64: dts: add device tree for ARM SMM-A53x2 on
LogicTile Express 20MG" added a new dts file to arch/arm64 which
included "../../../../arm/boot/dts/vexpress-v2m-rs1.dtsi", i.e. a
.dtsi supplied by arch/arm.

Unfortunately this causes some issues for the split device tree
repository[0], since things get moved around there. In that context
the new .dts ends up at src/arm64/arm/vexpress-v2f-1xv7-ca53x2.dts
while the include is at src/arm/vexpress-v2m-rs1.dtsi.

The sharing of the .dtsi is legitimate since the baseboard is the same
for various vexpress systems whatever processor they use.

Previously I attempted to resolve this by creating a shared location
for such things but we have been unable to come to a consensus on
where that should be.

Instead this patch simply replaces the use of ../../ in the dts
/include/ with a symlink in arch/arm64/boot/dts/arm pointing to the
file arch/arm/boot/dts.

Since the split device tree repo will shortly be required to flatten
symlinks for other reasons this will cause the dtsi file to appear in
both src/arm and src/arm64 in the split repo, which is an improvement
on not building for arm64 now.

a362ec8f67 arm64: dts: add all hi6220 uart nodes
This patch adds all UART nodes for the Hi6220 SoC. Recently a board[1] has
been developed to standardize UART access across all the 96boards consumer
edition boards. To use this hardware on HiKey we must configure and enable
UART3. However, to ensure backward compatibility we must keep UART0 enabled
as well.

I have removed the hard coded clock index values in favor of using the ones
already defined in include/dt-bindings/clock/hi6220-clock.h.

Since UART0 needs to be soldered, it has been suggested to use the UART3 as
the default console.

This patch was boot tested on top of next-20150930, with both UART
configurations.

a13f18f59d Documentation: arm: Fix typo in the idle-states bindings examples
The idle-states bindings mandate that the entry-method string
in the idle-states node must be "psci" for ARM v8 64-bit systems,
but the examples in the bindings report a wrong entry-method string.
Owing to this typo, some dts in the kernel wrongly defined the
entry-method property, since they likely cut and pasted the example
definition without paying attention to the bindings definitions.

This patch fixes the typo in the DT idle states bindings examples and
respective dts in the kernel so that the bindings and related dts
files are made compliant.

fc7e37c6b2 net: add Hisilicon Network Subsystem support (config and documents)
The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoC. The IP, which is called hns
for short, is a TCP/IP acceleration engine, which can directly decode
TCP/IP stream and distribute them to different ring buffers.

HNS can be configured to work on different mode for different scenario.
This patch make use only some of the mode to make it as standard
ethernet NIC. The other mode will be added soon.

The whole function has 4 kernel sub-modules:

hnae: the HNS acceleration engine framework. It provides a abstract
interface between the engine and the upper layers which make use of the
engine by ring buffer.

hns_enet_drv: a standard ethernet driver that base on the ring buffer.

hns_dsaf: one of the implementation of HNS acceleration engine, which is
applied on Hililicon hip05, Hi1610 and other later-on SoCs

hns_mdio: the mdio control to the PHY, used by acceleration engine

This submit add basic config and documents

a4fdb2a46f arm64 updates for 4.3:
- Support for new architectural features introduced in ARMv8.1:
   * Privileged Access Never (PAN) to catch user pointer dereferences in
     the kernel
   * Large System Extension (LSE) for building scalable atomics and locks
     (depends on locking/arch-atomic from tip, which is included here)
   * Hardware Dirty Bit Management (DBM) for updating clean PTEs
     automatically
 
 - Move our PSCI implementation out into drivers/firmware/, where it can
   be shared with arch/arm/. RMK has also pulled this component branch
   and has additional patches moving arch/arm/ over. MAINTAINERS is
   updated accordingly.
 
 - Better BUG implementation based on the BRK instruction for trapping
 
 - Leaf TLB invalidation for unmapping user pages
 
 - Support for PROBE_ONLY PCI configurations
 
 - Various cleanups and non-critical fixes, including:
   * Always flush FP/SIMD state over exec()
   * Restrict memblock additions based on range of linear mapping
   * Ensure *(LIST_POISON) generates a fatal fault
   * Context-tracking syscall return no longer corrupts return value when
     not forced on.
   * Alternatives patching synchronisation/stability improvements
   * Signed sub-word cmpxchg compare fix (tickled by HAVE_CMPXCHG_LOCAL)
   * Force SMP=y
   * Hide direct DCC access from userspace
   * Fix EFI stub memory allocation when DRAM starts at 0x0

8d01b66b4f ARM: SoC 64-bit changes for v4.3
Here's our branch of ARM64 contents for this merge window.
 
 Most of this is DT contents for new SoCs (or those who have seen new
 device support added). Maybe we should stop separating out the arm64
 contents here to avoid the kind of internal conflicts as we got this
 time around, where 32- and 64-bit contents conflicted.
 
 Anyhow, on the actual contents:
 
 New SoCs:
 
 - Broadcom North Star 2 (ns2)
 - Marvell Berlin4CT
 - Mediatek MT6795
 - Rockchip RK3368
 
 In addition, there are enhancements for the following platforms:
 
 - Mediatek MT8173: cpuidle-dt updates, misc other additions
 - ZyncMP: A bunch of devices added to the existing DTSI
 - Qualcomm MSM8916 and APQ8016 updates for USB, etc.
 
 + A handful of other updates for various platforms

341a670abd ARM64: dts: vexpress: Use assigned-clock-parents for sp810
The sp810 clk driver is calling the clk consumer APIs from
clk_prepare ops to change the parent to a 1 MHz fixed rate clock
for each of the clocks that the driver provides. Use
assigned-clock-parents for this instead of doing it in the driver
to avoid using the consumer API in provider code. This also
allows us to remove the usage of clk provider APIs that take a
struct clk as an argument from the sp810 driver.

0723c05fb7 arm64: enable more compressed Image formats
Plumb up Makefile arguments for the already supported formats in the kbuild
system: lz4, bzip2, lzma, and lzo.

Note that just as with Image.gz, these images are not self-decompressing and
the booting firmware still needs to handle decompression before launching the
kernel image.

Add a large window (up to 64GB) for X-Gene PCIe nodes to support devices
that require huge BARs.

Each X-Gene PCIe node will now have two memory windows: a 32-bit
non-prefetchable window and a 64-bit prefetchable window.

b790c2cab5 arm64: dts: add Rockchip rk3368 core dtsi and board dts for the r88 board
In terms of peripherals the rk3368 is quite similar to the rk3288, which
makes it possible to have a lot basic components working in the first go.
More to follow once I tracked down all the tiny differences that still
exist in some parts.

With these dts files, the R88 board is able to boot from an attached
usb device and most likely from its emmc too, if the emmc uses a standard
partition table instead of Rockchip's own one - the emmc itself is
detected correctly.

Some of these are for drivers/soc, where we're now putting

 - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
 - memory: support for Tegra132 SoC
 - memory: introduce tegra EMC driver for scaling memory frequency
 - misc. updates for ARM CCI and CCN busses
 
  Conflicts:

32270e805a ARM: SoC: driver updates for v4.2
Some of these are for drivers/soc, where we're now putting
 SoC-specific drivers these days. Some are for other driver subsystems
 where we have received acks from the appropriate maintainers.
 
 Some highlights:
 
 - simple-mfd: document DT bindings and misc updates
 - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
 - memory: support for Tegra132 SoC
 - memory: introduce tegra EMC driver for scaling memory frequency
 - misc. updates for ARM CCI and CCN busses
 
  Conflicts:
 	arch/arm64/boot/dts/arm/juno-motherboard.dtsi
 
  Trivial add/add conflict with our dt branch.
  Resolution: take both sides.

As usual, quite a few device-tree updates in ARM land.  There was ome
 minor churn in DTs due to relicensing under a dual-license, and lots
 of little additions of new peripherals, features etc, but nothing
 really exciting to call to your attention.  Some higlights, focsuing
 on support for new SoCs and boards:

 - tegra: HDA support
 - bcm: new platforms: Buffalo WXR-1900DHP, SmartRG SR400ac, ASUS RT-AC87U

   boards, DLink DNS-327L
 - OMAP: new platforms: Baltos IR5221, LogicPD Torpedo, Toby-Churchill SL50
 - ARM: added support for Juno r1 board
 - sunxi: A33 SoC support; new boards: A23 EVB, SinA33, GA10H-A33, Mele A1000G
 - imx: i.MX7D SoC support; new boards: Armadeus Systems APF6,

53bdd72c68 ARM64: juno: add GPIO keys
The Juno board has two keys connected to a PL061 GPIO block,
in accordance to DDI0524B "ARM Versatile Express Juno Development
Platform" revision 1.0, table 2-4 "GPIO (0) and GPIO (1) used
for additional user key entry". By trial-and-error I found that
these are connected to the two keys named "power" and "home"
on the motherboard.

Register the GPIO block and these two keys in the device tree
using the PL061 GPIO driver and the generic gpio keys.

- Map POWER, HOME, VOL+ and VOL- to the obvious input events.
- Map RLOCK to KEY_SCREENLOCK/KEY_COFFEE unless someone can
  explain better what this is for.
- Map the NMI button to KEY_SYSREQ as this is used like so
  in the SYSREQ debugging hack.

18c0b01530 arm64: Juno: Fix the GIC node address label and the frequency of FAXI clock.
During the review of the Juno DT files I've noticed that the GIC
node label had two digits swapped leading to a different address
being shown in the /sys/devices fs.

Sudeep also pointed that public revisions of the Juno documentation
list a different frequency for the FAXI system than what the one
I've been using when creating the DT file. Verified with the firmware
people to be the correct value in the shipped systems.

3ebee5a2e1 arm64: dts: kill skeleton.dtsi
While skeleton.dtsi was initially conceived as a simple way to bootstrap
writing a dts, it has proven to be problematic:

* The #address-cells and #size-cells values used in skeleton.dtsi may
  not match what a user wants (e.g. when they need to describe a range
  larger than 4GB).

* For dts files where memory nodes have unit-addresses, it adds a
  redundant /memory node, for which the reg entry may not be
  appropriately sized (e.g. where #size-cells has been overridden).

* For dts files which assume that a bootloader will fill in the memory
  node(s), no node is present in the dts (and hence there is no attached
  comment), making it hard to distinguish these cases from bad dts
  files, and masking any warnings dtc may produce w.r.t. missing nodes.

* The default empty /chosen and /aliases are somewhat useless, and it
  would be preferable for dts to fill these in (e.g. for
  /aliases/serial0 and /chosen/stdout-path).

This patch removes skeleton.dtsi from arm64. There are currently no
users, so we can remove it before any appear.

3bb1555c0d ARM64: juno: add sp810 support and fix sp804 clock frequency
The clock generator in IOFPGA generates the two source clocks: 32kHz and
1MHz for the SP810 System Controller.

The SP810 System Controller selects 32kHz or 1MHz as the sources for
TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but
the maximum of "refclk" and "timclk" is chosen by the SP810 driver.

This patch adds support for SP810 system controller and also fixes the
SP804 timer clock frequency.

However the SP804 driver needs to be enabled on ARM64 to test this,
which requires SP804 driver to be moved out of arch/arm.

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.

Dots aren't usually used in node names even though ePAPR permits
them.  However, this can easily be avoided by expressing the
frequency in Hz, not kHz.

This patch changes the name to refclk7273800hz, reflecting the
actual clock speed.

Commit 5d425c1865 ("arm64: kernel: add support for cpu cache

architectural way of detecting the cpus that share particular cache,
device tree can be used and the core cacheinfo already supports the
same.

This patch adds the L2 cache topology on Juno board, FVP/RTSM and
foundation models.

71a59b1272 ARM: SoC fixes
A week's worth of fixes for various ARM platforms. Diff wise, the
 largest fix is for OMAP to deal with how GIC now registers interrupts
 (irq_domain_add_legacy() -> irq_domain_add_linear() changes).
 
 Besides this, a few more renesas platforms needed the GIC instatiation
 done for legacy boards. There's also a fix that disables coherency of
 mvebu due to issues, and a few other smaller fixes.

e0b2180010 arm64: dts: add baud rate to Juno stdout-path
Without explicit command-line parameters, the Juno UART ends up running
at 57600 baud in the kernel, which is at odds with the 115200 baud used
by the rest of the firmware. Since commit 7914a7c565 now lets us
fix this by specifying default options in stdout-path, do so.

6c9e92476b ARM: SoC cleanups for 3.19
The remaining cleanups for 3.19 are to a large part result of
 devicetree conversion nearing completion on two other platforms
 besides AT91:
 
 * Like AT91, Renesas shmobile is in the process to migrate to DT and
   multiplatform, but using a different approach of doing it one
   SoC at a time. For 3.19, the r8a7791 platform and associated\
   "Koelsch" board are considered complete and we remove the non-DT
   non-multiplatform support for this.
 
 * The ARM Versatile Express has supported DT and multiplatform
   for a long time, but we have still kept the legacy board files
   around, because not all drivers were fully working before. We
   have finally taken the last step to remove the board files.
 
 Other changes in this branch are preparation for the later branches
 or just unrelated to the more interesting changes:
 * The dts files for arm64 get moved into per-vendor directories for
   a clearer structure.
 * Some dead code removal (zynq, exynos, davinci, imx)
 * Using pr_*() macros more consistently instead of printk(KERN_*)
   in some platform code.

Pull "dts, kbuild: Implement support for dtb vendor subdirs" from
Robert Richter:

dts, kbuild: Implement support for dtb vendor subdirs

For arm64 we want to put dts files into vendor's subdirectories from
the beginning. This patch set implements this. As this is a generic
kbuild implementation, vendor subdirs will be also available for
arch/arm and other architectures. The subdirectory tree is also
reflected in the install path.

A new makefile variable dts-dirs is introduced to point to dts
subdirs. This variable is used by kbuild for building and installation
of dtb files.

A dts Makefile looks now as follows:

----
dtb-$(CONFIG_...) += some_file_1.dtb
dtb-$(CONFIG_...) += some_file_2.dtb

dts-dirs          += dir_vendor_a
dts-dirs          += dir_vendor_b

always         := $(dtb-y)
subdir-y       := $(dts-dirs)
clean-files    := *.dtb
----

This patches also introduces the dtbs_install make target for
arm64. Install rules are moved to Makefile.dtbinst using the same
style and calling convention like for modinst and fwinst.

e2b6b35ee7 arm64: vexpress: Add CLCD support to the ARMv8 model platform
This patch enables CLCD support for the VE platform emulated by the
ARMv8 software model (DT bindings are based on Pawel's vexpress
patches) together with defconfig entries for SERIO_AMBAKMI and
FB_ARMCLCD.

323a028d39 dts, kbuild: Implement support for dtb vendor subdirs
This patch adds support of vendor sub directories for dtb files.
Subdirectories can be specified in $(dts-dirs). Kbuild traverses over
all directories while building and installing dtb files. The directory
tree is also reflected in the install path.

d38726c485 dts, arm/arm64: Remove dtbs build rules in sub-makes
Add dtb files to build targets and let kbuild handle them. Thus,
special dtbs rules can be removed. This eases Makefiles and the
implementation of the support of vendor dtb subdirectories.

9fb5e53722 dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst
Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be
defined. Another advantage is that install goals are not encoded in
targets anymore (%.dtb_dtbinst_).

862f464a54 dts, arm64: Add dtbs_install make target
This adds the dtbs_install make target to arm64. The target has been
introduced already to arch/arm with the following commit:

 f4d4ffc03e kbuild: dtbs_install: new make target

Implementation for arm64 is the same as for arm.

With 'dtbs_install' all config enabled dtb files are installed to
either the INSTALL_DTBS_PATH directory or the default location:

 $INSTALL_PATH/dtbs/$KERNELRELEASE

d5935b07da ARM64: SoC changes for 3.18
Starting with 3.18, we are merging SoC-specific changes for arm64 through
 the arm-soc tree, like we have been doing for arm32.
 
 This time, there is only one set of changes, adding support for the
 Cavium "Thunder" Soc family. Since the changes are relatively small,
 this includes Kconfig, defconfig and DT changes.
 
 If all goes well, we will never require adding actual C source code
 for platform support in arm64, given that the architecture is more
 clearly defined and we have moved out a lot of the platform specifics
 into device drivers for arm32 already.

3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver
