Once the dependency on PMU driver (for pad retention control) has been
removed, there is no reason to use syscore_ops based suspend/resume.
This patch replaces it with standard platform device pm_ops based solution.

This patch moves pad retention control from S5PV210 machine code to
Exynos pin controller driver. This helps to avoid possible ordering
and logical dependencies between machine and pin control code. Till
now it worked fine only because sys_ops for machine code and pin
controller were called in registration order.

This patch moves pad retention control from PMU driver to Exynos pin
controller driver. This helps to avoid possible ordering and logical
dependencies between machine, PMU and pin control code. Till now it
worked fine only because sys_ops for PMU and pin controller were called
in registration order.
This is also a preparation for adding new features to Exynos pin
controller driver, like runtime power management and suspending
individual pin controllers, which might be a part of some power domain.

Improvements for Exynos PMU driver for v4.11:
Beside basic function of setting proper configuration for low power modes, the
Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
for its registers. This regmap is essential to many other drivers wanting to
or needing to implement low power mode.
Exynos pinctrl driver, before getting support for Runtime Power Management,
needs access to this syscon regmap. Let's do it in a DT ABI friendly way.

PMU is something like a SoC wide service, so add a helper function to get
PMU regmap. This will be used by other Exynos device drivers. This way it
can be avoided to model this dependency in device tree (as phandles to PMU
node) for almost every device in the SoC.

Pull crypto fix from Herbert Xu:
"This fixes a hash corruption bug in the marvell driver"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: marvell - Copy IVDIG before launching partial DMA ahash requests

Currently, inner IV/DIGEST data are only copied once into the hash
engines and not set explicitly before launching a request that is not a
first frag. This is an issue especially when multiple ahash reqs are
computed in parallel or chained with cipher request, as the state of the
request being computed is not updated into the hash engine. It leads to
non-deterministic corrupted digest results.

Pull networking fixes from David Miller:
1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar.
The most important is to not assume the packet is RX just because
the destination address matches that of the device. Such an
assumption causes problems when an interface is put into loopback
mode.
2) If we retry when creating a new tc entry (because we dropped the
RTNL mutex in order to load a module, for example) we end up with
-EAGAIN and then loop trying to replay the request. But we didn't
reset some state when looping back to the top like this, and if
another thread meanwhile inserted the same tc entry we were trying
to, we re-link it creating an enless loop in the tc chain. Fix from
Daniel Borkmann.
3) There are two different WRITE bits in the MDIO address register for
the stmmac chip, depending upon the chip variant. Due to a bug we
could set them both, fix from Hock Leong Kweh.
4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan.

Commit beb0babfb77e ("korina: disable napi on close and restart")
introduced calls to napi_disable() that were missing before,
unfortunately this leaves a small window during which NAPI has a chance
to run, yet we just freed resources since korina_free_ring() has been
called:
Fix this by disabling NAPI first then freeing resource, and make sure
that we also cancel the restart task before doing the resource freeing.

In an IPvlan setup when master is set in loopback mode e.g.
ethtool -K eth0 set loopback on
where eth0 is master device for IPvlan setup.
The failure is caused by the faulty logic that determines if the
packet is from TX-path vs. RX-path by just looking at the mac-
addresses on the packet while processing multicast packets.
In the loopback-mode where this crash was happening, the packets
that are sent out are reflected by the NIC and are processed on
the RX path, but mac-address check tricks into thinking this
packet is from TX path and falsely uses dev_forward_skb() to pass
packets to the slave (virtual) devices.
This patch records the path while queueing packets and eliminates
logic of looking at mac-addresses for the same decision.

because PMU driver registered its sys_ops after pin controller.

Do not hide pinctrl drivers for Mediatek platforms using

Currently we already have two pin configuration related callbacks
available for GPIO chips .set_single_ended() and .set_debounce(). In
future we expect to have even more, which does not scale well if we need
to add yet another callback to the GPIO chip structure for each possible
configuration parameter.
Better solution is to reuse what we already have available in the
generic pinconf.
To support this, we introduce a new .set_config() callback for GPIO
chips. The callback takes a single packed pin configuration value as
parameter. This can then be extended easily beyond what is currently
supported by just adding new types to the generic pinconf enum.
If the GPIO driver is backed up by a pinctrl driver the GPIO driver can
just assign gpiochip_generic_config() (introduced in this patch) to
.set_config and that will take care configuration requests are directed
to the pinctrl driver.
We then convert the existing drivers over .set_config() and finally
remove the .set_single_ended() and .set_debounce() callbacks.

When a GPIO driver is backed by a pinctrl driver the GPIO driver
sometimes needs to call the pinctrl driver to configure certain things,
like whether the pin is used as input or output. In addition to this
there are other configurations applicable to GPIOs such as setting
debounce time of the GPIO.
To support this we introduce a new function pinctrl_gpio_set_config()
that can be used by gpiolib based driver to pass configuration requests
to the backing pinctrl driver.

The current pinconf packed format allows only 16-bit argument limiting
the maximum value 65535. For most types this is enough. However,
debounce time can be in range of hundreths of milliseconds in case of
mechanical switches so we cannot represent the worst case using the
current format.
In order to support larger values change the packed format so that the
lower 8 bits are used as type which leaves 24 bits for the argument.
This allows representing values up to 16777215 and debounce times up to
16 seconds.
We also convert the existing users to use 32-bit integer when extracting
argument from the packed configuration value.

This is less straight-forward than one would hope, as some banks only
have 4 pins rather than 8, others are output only, yet more (W and
X, already supported) are input-only, and in the case of the g4 SoC bank
AC doesn't exist.
Add some structs to describe the varying properties of different banks
and integrate mechanisms to deny requests for unsupported
configurations.

Incorrect video output configuration bits were being tested on pins in
GPIO banks AA and AB for the ROM{8,16} mux functions. The ROM{8,16}
functions are the highest priority for the relevant pins and also the
default function, so we require the relevant video output configuration
be disabled to mux GPIO functionality. As the wrong bits were being
tested a GPIO export would succeed but leave the pin in an unresponsive
state (i.e. value updates were ignored).
This misbehaviour was discovered as part of extending the GPIO
controller's support to cover banks Y, Z, AA, AB and AC (AC in the case
of the g5 SoC).

The Aspeed SoCs have more GPIOs than can be represented with A-Z. The
documentation uses two letter names such as AA and AB, so make the names
a three-character array in the bank struct to accommodate this.

The MSM pinctrl driver currently implements an irq_chip for handling
GPIO interrupts; due to how irq_chip handling is done, it's necessary
for the irq_chip methods to be invoked from hardirq context, even on a
a real-time kernel. Because the spinlock_t type becomes a "sleeping"
spinlock w/ RT kernels, it is not suitable to be used with irq_chips.
A quick audit of the operations under the lock reveal that they do only
minimal, bounded work, and are therefore safe to do under a raw
spinlock.
On real-time kernels, this fixes an OOPs which looks like the following,
as reported by Brian Wrenn:

Support for Exynos4415 is going away because there are no internal nor
