Pull ARM SoC fixes from Arnd Bergmann:
"Here are the latest bug fixes for ARM SoCs, mostly addressing recent
regressions. Changes are across several platforms, so I'm listing
every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent users from
relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be reworked
for 4.7 to avoid breaking boards other than the one they were
intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change with the
setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting clock on
the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after the
power domain changes for dra7
- On Mediatek, revert part of the power domain initialization changes
that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx suspend/resume
code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect for some
modern CPU cores.
- A hardware errata woraround for clockdomains on TI DRA7"

This is more prep-work for the upcoming pty changes. Still just code
cleanup with no actual semantic changes.
This removes a bunch pointless complexity by just having the slave pty
side remember the dentry associated with the devpts slave rather than
the inode. That allows us to remove all the "look up the dentry" code
for when we want to remove it again.
Together with moving the tty pointer from "inode->i_private" to
"dentry->d_fsdata" and getting rid of pointless inode locking, this
removes about 30 lines of code. Not only is the end result smaller,
it's simpler and easier to understand.
The old code, for example, depended on the d_find_alias() to not just
find the dentry, but also to check that it is still hashed, which in
turn validated the tty pointer in the inode.
That is a _very_ roundabout way to say "invalidate the cached tty
pointer when the dentry is removed".
The new code just does
dentry->d_fsdata = NULL;
in devpts_pty_kill() instead, invalidating the tty pointer rather more
directly and obviously. Don't do something complex and subtle when the
obvious straightforward approach will do.
The rest of the patch (ie apart from code deletion and the above tty
pointer clearing) is just switching the calling convention to pass the
dentry or file pointer around instead of the inode.

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.
This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.
Fixes bugs 113331 and 114941.

This patch introduces kexec support for mlx5.
When switching kernels, kexec() calls shutdown, which unloads
the driver and cleans its resources.
In addition, remove unregister netdev from shutdown flow. This will
allow a clean shutdown, even if some netdev clients did not release their
reference from this netdev. Releasing The HW resources only is enough as
the kernel is shutting down

Set and report vport MTU rather than physical MTU,
Driver will set both vport and physical port mtu and will
rely on the query of vport mtu.
SRIOV VFs have to report their MTU to their vport manager (PF),
and this will allow them to work with any MTU they need
without failing the request.
Also for some cases where the PF is not a port owner, PF can
work with MTU less than the physical port mtu if set physical
port mtu didn't take effect.

In the error flow of adding flow rule to auto-grouped flow
table, we call to tree_remove_node.
tree_remove_node locks the node's parent, however the node's parent
is already locked by mlx5_add_flow_rule and this causes a deadlock.
After this patch, if we failed to add the flow rule, we unlock the
flow table before calling to tree_remove_node.

Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe()
in stmmac_main.c functions call devm_reset_control_get() to register an
reset controller for the stmmac. This results in an attempt to register
two reset controllers for the same non-shared reset line.
The first attempt to register the reset controller works fine. The second
attempt fails with warning from the reset controller core, see below.
The warning is produced because the reset line is non-shared and thus
it is allowed to have only up-to one reset controller associated with
that reset line, not two or more.
The solution has multiple parts. First, the original socfpga_dwmac_init()
is tweaked to use reset controller pointer from the stmmac_priv (private
data of the stmmac core) instead of the local instance, which was used
before. The local re-registration of the reset controller is removed.
Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the
probe function. This order is legal according to Altera and it makes the
code much easier, since there is no need to temporarily register and
unregister the reset controller ; the reset controller is already registered
by the stmmac_dvr_probe().
Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary,
since the functionality is already performed by the stmmac core.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Merge "omap fixes against v4.6-rc2" from Tony Lindgren
Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.
It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.
Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.
Also included is a fix for dra7 sys_32k_ck clock source that is not
enabled on boot making system fall back to using emulated clock.

The exynos5 I2C controller driver always prepares and enables a clock
before using it and then disables unprepares it when the clock is not
used anymore.
But this can cause a possible ABBA deadlock in some scenarios since a
driver that uses regmap to access its I2C registers, will first grab
the regmap lock and then the I2C xfer function will grab the prepare
lock when preparing the I2C clock. But since the clock driver also
uses regmap for I2C accesses, preparing a clock will first grab the
prepare lock and then the regmap lock when using the regmap API.
An example of this happens on the Exynos5422 Odroid XU4 board where a
s2mps11 PMIC is used and both the s2mps11 regulators and clk drivers
share the same I2C regmap.
The possible deadlock is reported by the kernel lockdep:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
*** DEADLOCK ***
Fix it by leaving the code prepared on probe and use {en,dis}able in
the I2C transfer function.
This patch is similar to commit 34e81ad5f0b6 ("i2c: s3c2410: fix ABBA
deadlock by keeping clock prepared") that fixes the same bug in other
driver for an I2C controller found in Samsung SoCs.

Haswell and Broadwell can be configured to hash the channel
interleave function using bits [27:12] of the physical address.
On those processor models we must check to see if hashing is
enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and
act accordingly.

In commit:
eb1af3b71f9d ("Fix computation of channel address")
I switched the "sck_way" variable from holding the log2 value read
from the h/w to instead be the actual number. Unfortunately it
is needed in log2 form when used to shift the address.

Commit 0881841f7e78 introduced a regression by inverting a test check
after calling clocksource_mmio_init(). That results on the system to
hang at boot time.
Fix it by inverting the test again.
