ARM: dts: am437x-sk-evm: Reduce i2c0 bus speed for tps65218
Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

ARM: OMAP2+: timer: add probe for clocksources
A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource. This will tick in periodic mode, preventing any deeper idle states. While here, also drop one unnecessary check for populated DT before existing clocksource_probe() call.

arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections
KASAN needs to know whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. Move the definition of __irq_entry to <linux/interrupt.h> so that the users don't need to pull in <linux/ftrace.h>. Also introduce the __softirq_entry macro which is similar to __irq_entry, but puts the corresponding functions to the .softirqentry.text section.

asm-generic changes for 4.6
There are only three patches this time, most other changes to files in include/asm-generic tend to go through the tree of whoever depends on the change. Two patches are cleanups for stuff that is no longer needed, the main change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to make it behave consistently with BUG(). This avoids undefined behavior along with a number of warnings about that undefined behavior in randconfig builds when we keep going on after hitting a BUG_ON(). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVvRXDGCrR//JCVInAQKUFRAAmp23pohv08LZzXL8Qu7XfFN+b1RkZ936 WYBeiA9PEWufQs2hgXaEUXy0onO7ah4cs2NWfkaBPyxT+I9mN+ThdzqVrlTE+AEO 2K0f2RaZANC238zB86Yv/YvTj7FegH0DDdMBq/P06vlYdgBegx49U3pMpguxl3d0 /q9MyqTzo9j4uOEK4ix4/Dko+4eKIS5Y/xeb0TkeKA6HiBVzAhGLZFl+eMku07Bf ap8B705hBDXSBFeWcK9AvKjHZCM+FCkb+C3TXo9x5tUu8g5OIG1t962OQvT9ldsP rvo5ppRh/TAY2Z9chN3cKrsvshbHiZ9uRzeksCunL+SK+dOhEIPCVzLXndQpi3RD NgeNKgo6gKYdle44pEj0EH2ktuvr0u8sbjQg9SY2miC1H4DmEbCakSqtQegHXTKd chJ6xyNiQXktdfo0pFOtCA2gjqiAriugttBqUtGcK9zRqjGGpP5hOUQVm3jR7UMp Hjb+oj5o+Gjz5J1t5zsjbhFINDCHAgXRzqqaoT9RfE9+QlUftUhu+N9KVFgzhe9I 93VHaqgGIRoi856BO7UZSaMGhy7ljm1nQ18jP9aZl/tBco0kpd3AO8og9dJ0u2j+ 3fEqAHH30ia8GJCfIDnolxTL6uaqcCIeAoLgGcmn+QZS7ka+tD+000rtgd2pdy9/ gy/VPpFG064= =8tPL -----END PGP SIGNATURE----- Merge tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are only three patches this time, most other changes to files in include/asm-generic tend to go through the tree of whoever depends on the change.

ARM: DT changes, part 2
Here are some final updates for ARM SoC specific dts files:
* The i.MX changes were sent relatively late, and had a dependency
on the clk tree, so I delayed that a bit. Support for the new
i.MX6qp SoC and a couple of new boards is added in this branch.
* Uniphier renames a few files to match the final product names
that were decided by the company, kudos to the kernel developer(s)
for getting support upstream before the product release.
Also two boards are added. The patches were posted early enough
and nice overall, but we forgot to apply them and decided to
give it some more time in linux-next
* at91 has two small bug fixes.

The clk changes for this release cycle are mostly dominated by
new device support in terms of LoC, but there has been some cleanup
in the core as well as the usual minor clk additions to various
drivers.
Core:
- parent tracking has been simplified
- CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
- of_clk_init() doesn't consider disabled DT nodes anymore
- clk_unregister() had an error path bug squashed
- of_clk_get_parent_count() has been fixed to only return unsigned ints
- HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
New Drivers:
- NXP LPC18xx creg
- QCOM IPQ4019 GCC
- TI dm814x ADPLL
- i.MX6QP
Updates:
- Cyngus audio clks found on Broadcom iProc devices
- Non-critical fixes for BCM2385 PLLs
- Samsung exynos5433 updates for clk id errors, HDMI support,
suspend/resume simplifications
- USB, CAN, LVDS, and FCP clks on shmobile devices
- sunxi got support for more clks on new SoCs and went through a minor
refactoring/rewrite to use a simpler factor clk construct
- rockchip added some more clk ids and added suport for fraction dividers
- QCOM GDSCs in msm8996
- A new devm helper to make adding custom actions simpler (acked by Greg)

xen: audit usages of module.h ; remove unnecessary instances
Code that uses no modular facilities whatsoever should not be sourcing module.h at all, since that header drags in a bunch of other headers with it. Similarly, code that is not explicitly using modular facilities like module_init() but only is declaring module_param setup variables should be using moduleparam.h and not the larger module.h file for that. In making this change, we also uncover an implicit use of BUG() in inline fcns within arch/arm/include/asm/xen/hypercall.h so we explicitly source <linux/bug.h> for that file now.

ARM: SoC driver updates for v4.6
Driver updates for ARM SoCs, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons:
- Rockchip rk3368 gains power domain support
- Small updates for the ARM spmi driver
- The Atmel PMC driver saw a larger rework, touching both
arch/arm/mach-at91 and drivers/clk/at91
- All reset controller driver changes alway get merged through
arm-soc, though this time the largest change is the addition
of a MIPS pistachio reset driver
- One bugfix for the NXP (formerly Freescale) i.MX weim bus driver

ARM: SoC defconfig updates for v4.6
As usual, a bunch of commits, mostly adding drivers and other options to defconfigs. The realview_smp_defconfig and realview_defconfig got merged into one, so we are now down to 110 files. For stm32, we have now added a Kconfig fragment, the first such file on arch/arm. The purpose here is to have a shared defconfig file that works for all boards, while the DRAM offset has to be hardwired on NOMMU machines at compile time. The Exynos defconfig changes depend on changes in the RTC tree, so this is pulled in here, but has already been merged into 4.6 now. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVu67N2CrR//JCVInAQIW4A//YRCJQV8655S9OmFtGU7/Yl541KIvlaYs mrmiGtqtjQ4rJjtW1f9vhQsls+ZC1eFL194/beS/9FNThJNp5ZuZTkXce1j/m2xY umcsV8emYx0KATIyUIrrXu1LX/BwdXwcZxu0WZDIYdtRgY+94PmS0xqHM98jCmKV yRuPgYk4cre8GWX2Bg4WdzqKCK/TIdJYz2uprP3xQ7QDi8BFDPx8EuKXLgDwzZ3a WRztWMzK2aAoJjZBSxr8jMx6F2Cl1xYm+Hjt81u2czqSHx3q8s9JWiEGqZqurRdh DbQ4jAeqh1shEemf85wcPthDZGVxSmJs0Ct0ewIpjnMqYAaxiVShUtTjxgcmdyyK XsRRgcWXZdFT0+plyh08BvzXPMWsYif/BPFnXFILSyrUGulN1rV75Xi47OfooPOD RwyiieE/u8iEbcPKH5rxQmUb7uKdNJ1xu3XfTJibXd8cp8LnbLjfTPE8V0/DPKZb 88DoxovjTFPHRNT4YlFFeK8qjzngPoGwysX1X8bvsMuk5c0ibA5H5XmRHqh7KiUH Qjk1RNkZ2t6W2YVNwt5qTyaXdIH4Itschy0d8L+pdhsZ7ysB7jMwsQvMm3CQhm84 5xHjHuZgGbJZNOpLs1jbyBx7V0cOpafaZTfDeLhfBmnofJwWGv6Yw1Mz+VzZXOW9 KcwWvYGiYUA= =d4mQ -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Arnd Bergmann: "As usual, a bunch of commits, mostly adding drivers and other options to defconfigs.

ARM: SoC cleanups for v4.6
A few simple cleanups across multiple platforms, not much standing out:
- lpc32xx removes its private implementation of the clk API, after
generic code was merged in 4.5
- all unused Makefile.boot files get removed
- a number of simplifications for shmobile
- asm/clkdev.h gets replaced with the asm-generic version after
all mach/clkdev.h implementations are gone

"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

During the review process of the UniPhier System Bus driver (drivers/bus/uniphier.c), the current binding of the System Bus Controller turned out to be no good.

ARM: uniphier: rework SMP code to support new System Bus binding
During the review process of the UniPhier System Bus driver (drivers/bus/uniphier.c), the current binding of the System Bus Controller turned out to be no good. In order to use the driver, some nodes in the device trees must be tweaked. It would also have impacts on the SMP code because the SMP related registers are located in the System Bus Controller block.

This is the bulk of GPIO changes for kernel v4.6:
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.
- Texas Instruments TPIC2810
- Texas Instruments TPS65218
- Texas Instruments TPS65912
- X-Gene (ARM64) standby GPIO controller

arm64 updates for 4.6:
- Initial page table creation reworked to avoid breaking large block
mappings (huge pages) into smaller ones. The ARM architecture requires
break-before-make in such cases to avoid TLB conflicts but that's not
always possible on live page tables
- Kernel virtual memory layout: the kernel image is no longer linked to
the bottom of the linear mapping (PAGE_OFFSET) but at the bottom of
the vmalloc space, allowing the kernel to be loaded (nearly) anywhere
in physical RAM
- Kernel ASLR: position independent kernel Image and modules being
randomly mapped in the vmalloc space with the randomness is provided
by UEFI (efi_get_random_bytes() patches merged via the arm64 tree,
acked by Matt Fleming)
- Implement relative exception tables for arm64, required by KASLR
(initial code for ARCH_HAS_RELATIVE_EXTABLE added to lib/extable.c but
actual x86 conversion to deferred to 4.7 because of the merge
dependencies)
- Support for the User Access Override feature of ARMv8.2: this allows
uaccess functions (get_user etc.) to be implemented using LDTR/STTR
instructions. Such instructions, when run by the kernel, perform
unprivileged accesses adding an extra level of protection. The
set_fs() macro is used to "upgrade" such instruction to privileged
accesses via the UAO bit
- Half-precision floating point support (part of ARMv8.2)
- Optimisations for CPUs with or without a hardware prefetcher (using
run-time code patching)
- copy_page performance improvement to deal with 128 bytes at a time
- Sanity checks on the CPU capabilities (via CPUID) to prevent
incompatible secondary CPUs from being brought up (e.g. weird
big.LITTLE configurations)
- valid_user_regs() reworked for better sanity check of the sigcontext
information (restored pstate information)
- ACPI parking protocol implementation
- CONFIG_DEBUG_RODATA enabled by default
- VDSO code marked as read-only
- DEBUG_PAGEALLOC support

There are few things about *pte_alloc*() helpers worth cleaning up: - 'vma' argument is unused, let's drop it; - most __pte_alloc() callers do speculative check for pmd_none(), before taking ptl: let's introduce pte_alloc() macro which does the check. The only direct user of __pte_alloc left is userfaultfd, which has different expectation about atomicity wrt pmd. - pte_alloc_map() and pte_alloc_map_lock() are redefined using pte_alloc().
