A patch to fix the return value of clk_round_rate()
* tag 'davinci-for-v3.14/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
ARM: davinci: clock: return 0 upon error from clk_round_rate()
DT-enabled Marvell Kirkwood and Dove SoCs make use of an irqchip
driver. As expected for irqchip drivers, it uses a C-style
interrupt handler and therefore selects MULTI_IRQ_HANDLER.
Now, compiling a kernel with both non-DT and DT support enabled,
selecting MULTI_IRQ_HANDLER will break ASM irq handler used by
non-DT boards.
Therefore, we provide a C-style irq handler even for non-DT boards,
if MULTI_IRQ_HANDLER is set. By installing the C-style irq handler
in orion_irq_init this is transparent to all non-DT board files.
While the regression report was filed on Marvell Kirkwood, also
Marvell Dove non-DT boards are affected and fixed by this patch.

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).
This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the

Previously the custom GPIO header for the S3C24xx would in turn
bring in the custom pin control implementation from

the dependency explicit by explicitly including the pin

The first variants of Armada XP SoCs (A0 stepping) have issues related
to the i2c controller which prevent to use the offload mechanism and
lead to a kernel hang during boot.
This commit add quirk in the mvebu platform code to check the SoC
version and then update the compatible string for the i2c controller
according to the revision of the SoC. Currently only some OpenBlocks
AX3-4 boards are known to use an A0 revision so the check is done only
for these boards.

Add the syscalls needed for supporting scheduling algorithms
with extended scheduling parameters (e.g., SCHED_DEADLINE).
In general, it makes possible to specify a periodic/sporadic task,
that executes for a given amount of runtime at each instance, and is
scheduled according to the urgency of their own timing constraints,
i.e.:
- a (maximum/typical) instance execution time,
- a minimum interval between consecutive instances,
- a time constraint by which each instance must be completed.
Thus, both the data structure that holds the scheduling parameters of
the tasks and the system calls dealing with it must be extended.
Unfortunately, modifying the existing struct sched_param would break
the ABI and result in potentially serious compatibility issues with
legacy binaries.
For these reasons, this patch:
- defines the new struct sched_attr, containing all the fields
that are necessary for specifying a task in the computational
model described above;
- defines and implements the new scheduling related syscalls that
manipulate it, i.e., sched_setattr() and sched_getattr().
Syscalls are introduced for x86 (32 and 64 bits) and ARM only, as a
proof of concept and for developing and testing purposes. Making them
available on other architectures is straightforward.
Since no "user" for these new parameters is introduced in this patch,
the implementation of the new system calls is just identical to their
already existing counterpart. Future patches that implement scheduling
policies able to exploit the new data structure must also take care of
modifying the sched_*attr() calls accordingly with their own purposes.

Kexec disables outer cache before jumping to reboot code, but it doesn't
flush it explicitly. Flush is done implicitly inside of l2x0_disable().
But some SoC's override default .disable handler and don't flush cache.
This may lead to a corrupted memory during Kexec reboot on these
platforms.
This patch adds cache flush inside of OMAP4 and Highbank outer_cache.disable()
handlers to make it consistent with default l2x0_disable().

A number of situations currently require the heavyweight smp_mb(),
even though there is no need to order prior stores against later
loads. Many architectures have much cheaper ways to handle these
situations, but the Linux kernel currently has no portable way
to make use of them.
This commit therefore supplies smp_load_acquire() and
smp_store_release() to remedy this situation. The new
smp_load_acquire() primitive orders the specified load against
any subsequent reads or writes, while the new smp_store_release()
primitive orders the specifed store against any prior reads or
writes. These primitives allow array-based circular FIFOs to be
implemented without an smp_mb(), and also allow a theoretical
hole in rcu_assign_pointer() to be closed at no additional
expense on most architectures.
In addition, the RCU experience transitioning from explicit
smp_read_barrier_depends() and smp_wmb() to rcu_dereference()
and rcu_assign_pointer(), respectively resulted in substantial
improvements in readability. It therefore seems likely that
replacing other explicit barriers with smp_load_acquire() and
smp_store_release() will provide similar benefits. It appears
that roughly half of the explicit barriers in core kernel code
might be so replaced.

The MPIDR contains specific bitfields(MPIDR.Aff{2..0}) which uniquely
identify a CPU, in addition to some non-identifying information and
reserved bits. The ARM cpu binding defines the 'reg' property to only
contain the affinity bits, and any cpu nodes with other bits set in
their 'reg' entry are skipped.
As such it is not necessary to mask the phys_id with MPIDR_HWID_BITMASK,
and doing so could lead to matching erroneous CPU nodes in the device
tree. This patch removes the masking of the physical identifier.

The EXYNOS cpuidle driver code assumes that cpuidle core will handle
dev->state_count smaller than drv->state_count but currently this is
untrue (dev->state_count is used only for handling cpuidle state sysfs
entries and drv->state_count is used for all other cases) and will not
be fixed in the future as dev->state_count is planned to be removed.
Fix the issue by checking for the max supported idle state in AFTR
state's ->enter handler (exynos4_enter_lowpower()) and entering AFTR
mode only when cores other than CPU0 are offline.

Hopefully the last set of arm-soc fixes for 3.13, or at least only a
few stray patches after this.
There are a few fixes for Renesas platforms to fixup DMA masks (this
started causing errors once the DMA API added checks for valid masks in
3.13). Two more dealing with resources for MMC and PWM setup.
There's also a few TI/OMAP/DRA fixes for smaller stuff and a fix for
compilation failures on a PXA platform.

The THP code in KVM/ARM is a bit restrictive in not allowing a THP
to be used if the VMA is not 2MB aligned. Actually, it is not so much
the VMA that matters, but the associated memslot:
A process can perfectly mmap a region with no particular alignment
restriction, and then pass a 2MB aligned address to KVM. In this
case, KVM will only use this 2MB aligned region, and will ignore
the range between vma->vm_start and memslot->userspace_addr.
It can also choose to place this memslot at whatever alignment it
wants in the IPA space. In the end, what matters is the relative
alignment of the user space and IPA mappings with respect to a
2M page. They absolutely must be the same if you want to use THP.

The omap3_pmx_core pinmux device in the device tree handles the system
controller module (SCM) PADCONFS fonction. Its control registers are
split in two distinct areas, with other SCM registers in-between. Those
other registers can't thus be requested by other drivers as the memory
region gets reserved by the pinmux driver.
Split the omap3_pmx_core device tree node in two for the two memory
regions. The second region address and size depends on the SoC model.
The change in omap3.dtsi fixes an "external abort on non-linefetch" when
doing
cat /sys/kernel/debug/pinctrl/.../pins

The 'xen_hvm_resume_frames' used to be an 'unsigned long'
and contain the virtual address of the grants. That was OK
for most architectures (PVHVM, ARM) were the grants are contiguous
in memory. That however is not the case for PVH - in which case
we will have to do a lookup for each virtual address for the PFN.
Instead of doing that, lets make it a structure which will contain
the array of PFNs, the virtual address and the count of said PFNs.
Also provide a generic functions: gnttab_setup_auto_xlat_frames and
gnttab_free_auto_xlat_frames to populate said structure with
appropriate values for PVHVM and ARM.
To round it off, change the name from 'xen_hvm_resume_frames' to
a more descriptive one - 'xen_auto_xlat_grant_frames'.
For PVH, in patch "xen/pvh: Piggyback on PVHVM for grant driver"
we will populate the 'xen_auto_xlat_grant_frames' by ourselves.
v2 moves the xen_remap in the gnttab_setup_auto_xlat_frames
and also introduces xen_unmap for gnttab_free_auto_xlat_frames.

Samsung Clock fixes for 3.13-rc7
* Several patches fixing up incorrectly defined register addresses and
bitfield offsets that could lead to undefined operation when accessing
respective registers or bitfields.
1) clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks
2a) clk: samsung: exynos5250: Fix ACP gate register offset
2b) clk: samsung: exynos5250: Add MDMA0 clocks
2c) ARM: dts: exynos5250: Fix MDMA0 clock number
3) clk: samsung: exynos4: Correct SRC_MFC register
All three issues have been present since Exynos5250 and Exynos4 clock
drivers were added by commits 6e3ad26816 ("clk: exynos5250:
register clocks using common clock framework") and e062b57177
("clk: exynos4: register clocks using common clock framework")
respectively.
* Patch to fix automatic disabling of Exynos5250 sysreg clock that could
cause undefined operation of several peripherals, such as USB, I2C,

* Patch fixing compilation warning in clk-exynos-audss driver when
CONFIG_PM_SLEEP is disabled.
5) clk: exynos: File scope reg_save array should depend on PM_SLEEP
Present since the driver was added by commit 1241ef94cc ("clk:
samsung: register audio subsystem clocks using common clock
framework").
This fixes the issue introduced by the following commit:
b448c904f5 "ARM: shmobile: r8a7790: add I2C support"
The R8A7790 is an R-Car Gen2 SoC. The clock division factor
(CDF) width is 3 bits on Gen2 as opposed to 2 bits on Gen1.
Fix the device names for R8A7790 SoC to make the R-Car I2C
driver configure the hardware properly.
Changes in V2:
* rebased on top of the latest branch;
* capitalized ARM in the subject line;
* noted the commit that caused the issue in the log.

Pull ARM fixes from Russell King:
"Another set of small fixes for ARM, covering various areas.
Laura fixed a long standing issue with virt_addr_valid() failing to
handle holes in memory. Steve found a problem with dcache flushing
for compound pages. I fixed another bug in footbridge stuff causing
time to tick slowly, and also a problem with the AES code which can
cause linker errors.
A patch from Rob which fixes Xen problems induced by a lack of
consistency in our naming of ioremap_cache() - which thankfully has
very few users"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:

The BCM2835 SoC contains a DWC2 USB controller. Add this to the DT.
Set up the pin controller to fully enable the USB controller on the
Raspberry Pi. The GPIO setup works because the default output value for
GPIO 6 (LAN_RUN/n_reset) just happens to be 1, which enables the
USB/LAN chip.
Note that you'll need a U-Boot which enables power to the USB controller;
search for U-Boot patch "ARM: rpi_b: power on SDHCI and USB HW modules".

ERR007265: CCM: When improper low-power sequence is used, the SoC
enters low power mode before the ARM core executes WFI.
Software workaround:
1) Software should trigger IRQ #32 (IOMUX) to be always pending
by setting IOMUX_GPR1_GINT.
2) Software should then unmask IRQ #32 in GPC before setting CCM
Low-Power mode.
