Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Support Touchpad MCU as a special of CrOS EC devices. The current
Touchpad MCU is used on Eve Chromebook and used the same protocol as
other CrOS EC devices.

When a MCU has touchpad support (aka EC_FEATURE_TOUCHPAD), it is
instantiated as a special CrOS EC device with device name 'cros_tp'. So
regardless of the probing order between the actual cros_ec and cros_tp,
the userspace and other kernel drivers should not confuse them.

Su Bao Cheng a9bf6aa699 mfd: intel_quark_i2c_gpio: Adjust IOT2000 matching
Since there are more IOT2040 variants with identical hardware but
different asset tags, the asset tag matching should be adjusted to
support them.

For the board name "SIMATIC IOT2000", currently there are 2 types of
hardware, IOT2020 and IOT2040. Both are identical regarding the
intel_quark_i2c_gpio. In the future there will be no other devices with
the "SIMATIC IOT2000" DMI board name but different hardware. So remove
the asset tag matching from this driver.

Maxime Ripard 4f799e47ad mfd: axp20x: Allow the AXP223 to be probed by I2C
The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.

Let's add that possibility.

Tony Lindgren 48171d0ea7 mfd: twl6040: Fix device init errors for ACCCTL register
I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:

twl6040 0-004b: Failed to write 2d = 19: -121

And then any following register access will produce errors.

There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.

To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.

Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.

Masahiro Yamada 4c11edfcf7 Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.

A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.

To avoid the build errors, the lines referencing to the undefined
macro must be removed.

The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.

For now, I am touching only the offending lines.

There are two drivers that are relying on the iDMA 64-bit driver name
to match. Instead of duplicating string in both of them, dedicate
a header file and share it between users.

Since this driver only has a dependency on ARCH_SUNXI just because it

enable it through COMPILE_TEST as well to get some build coverage.

Thor Thayer f36e789a1f mfd: altera-sysmgr: Add SOCFPGA System Manager
The SOCFPGA System Manager register block aggregates different
peripheral functions into one area.
On 32 bit ARM parts, handle in the same way as syscon.
On 64 bit ARM parts, the System Manager can only be accessed by
EL3 secure mode. Since a SMC call to EL3 is required, this new
driver uses regmaps similar to syscon to handle the SMC call.

Since regmaps abstract out the underlying register access, the
changes to drivers accessing the System Manager are minimal.

Andreas Kemnade 20bb907f7d mfd: twl-core: Disable IRQ while suspended
Since commit 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")
on gta04 we have handle_twl4030_pih() called in situations where pm_runtime_get()
in i2c-omap.c returns -EACCES.

This happens when we wakeup via something behing twl4030 (powerbutton or rtc
alarm). This goes on for minutes until the system is finally resumed.
Disable the irq on suspend and enable it on resume to avoid
having i2c access problems when the irq registers are checked.

Linus Torvalds 3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be
   phased over to use pin control. We do not yet provide a
   userspace ABI for this pull up-down setting but I suspect
   the makers are going to ask for it soon enough. PCA953x
   is the first user of this new API.
 
 - The GPIO mockup driver has been revamped after some
   discussion improving the IRQ simulator in the process.
   The idea is to make it possible to use the mockup for
   both testing and virtual prototyping, e.g. when you do
   not yet have a GPIO expander to play with but really
   want to get something to develop code around before
   hardware is available. It's neat. The blackbox testing
   usecase is currently making its way into kernelci.
 
 - ACPI GPIO core preserves non direction flags when updating
   flags.
 
 - A new device core helper for devm_platform_ioremap_resource()
   is funneled through the GPIO tree with Greg's ACK.
 
 New drivers:
 
 - TQ-Systems QTMX86 GPIO controllers (using port-mapped
   I/O)
 
 - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
 
 - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
 
 - Fintek F81804 & F81966 subvariants.
 
 - PCA953x now supports NXP PCAL6416.
 
 Driver improvements:
 
 - IRQ support on the Nintendo Wii (Hollywood) GPIO.
 
 - get_direction() support for the MVEBU driver.
 
 - Set the right output level on SAMA5D2.
 
 - Drop the unused irq trigger setting on the Spreadtrum
   driver.
 
 - Wakeup support for PCA953x.
 
 - A slew of cleanups in the various Intel drivers.

Linus Torvalds 384d11fa0e ARM: SoC driver updates for 5.1
As usual, the drivers/tee and drivers/reset subsystems get merged
 here, with the expected set of smaller updates and some new hardware
 support. The tee subsystem now supports device drivers to be attached
 to a tee, the first example here is a random number driver with its
 implementation in the secure world.
 
 Three new power domain drivers get added for specific chip families:
  - Broadcom BCM283x chips (used in Raspberry Pi)
  - Qualcomm Snapdragon phone chips
  - Xilinx ZynqMP FPGA SoCs
 
 One new driver is added to talk to the BPMP firmware on NVIDIA
 Tegra210
 
 Existing drivers are extended for new SoC variants from NXP,
 NVIDIA, Amlogic and Qualcomm.

Currently the sm501 mfd driver can be compiled without any dependencies,
but through the use of dma_declare_coherent it really depends on
having DMA and iomem support.  Normally we don't explicitly require DMA
support as we have stubs for it if on UML, but in this case the driver
selects support for dma_declare_coherent and thus also requires
memmap support.  Guard this by an explicit dependency.

Now that ssbi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.

This change was tested on an APQ8060 DragonBoard.

Brian Masney ee08e24c2e mfd: pm8xxx: disassociate old virq if hwirq mapping already exists
Check to see if the hwirq is already associated with another virq on
this IRQ domain. If so, then disassociate it before associating the
hwirq with the new virq.

This is a temporary hack that is needed in order to not break git
bisect for existing boards. The next patch in this series converts
ssbi-gpio to be a hierarchical IRQ chip, then there are several patches
to update all of the device tree files, and finally this patch will be
reverted within the same patch series.

IRQs for ssbi-gpio are all initially setup without an IRQ hierarchy
this driver is probed due to the interrupts property in device tree.
Once ssbi-gpio is converted to be a hierarchical IRQ chip in the next
patch, existing users of gpio[d]_to_irq() will call pmic_gpio_to_irq(),
and that will use the new IRQ chip code in ssbi-gpio that sets up the
IRQ in an IRQ hierarchy. The hwirq is now associated with two Linux
virqs and interrupts will not work as expected. This patch corrects
that issue.

Brian Masney 3324a7c1a2 mfd: pm8xxx: convert to v2 irq interfaces to support hierarchical IRQ chips
Convert the PM8XXX IRQ code to use the version 2 IRQ interface in order
to support hierarchical IRQ chips. This is necessary so that ssbi-gpio
can be setup as a hierarchical IRQ chip with PM8xxx as the parent. IRQ
chips in device tree should be usable from the start without having to
make an additional call to gpio[d]_to_irq() to get the proper IRQ on the
parent.

pm8821_irq_domain_ops and pm8821_irq_domain_map are removed by this
patch since the irq_chip is now contained in the pm_irq_data struct, and
that allows us to use a common IRQ mapping function.

While ioctls normally return a negative error or 0 on success, this is not
the case for CROS_EC_DEV_IOCXCMD in the cros_ec driver, which returns the
number of bytes read instead. However, CROS_EC_DEV_IOCRDMEM in the same

Paul Gortmaker 66265e719b mfd: tps68470: Drop unused MODULE_DEVICE_TABLE
The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_TPS68470
drivers/mfd/Kconfig:    bool "TI TPS68470 Power Management / LED chips"

...meaning that it currently is not being built as a module by anyone.

Hence we remove the MODULE_DEVICE_TABLE since it is a no-op for
non-modular code.

There is no removal of <linux/module.h> here because there isn't one.
Instead, it is relying on including that implicitly from an ACPI header.

In cleaning up the ACPI instance of module.h (which also isn't strictly
needed), then this mfd driver breaks when MODULE_DEVICE_TABLE becomes
undefined here.

The easiest dependency solution is to simply defer the ACPI cleanup
until this change is present in mainline.

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board. Audio system topology,
clocking and power can all be controlled through the Lochnagar
controller chip, allowing the device under test to be used in
a variety of possible use cases.

As the Lochnagar is a fairly complex device this MFD driver
allows the drivers for the various features to be bound
in. Initially clocking, regulator and pinctrl will be added as
these are necessary to configure the system. But in time at least
audio and voltage/current monitoring will also be added.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

Fix this by making above options to depend on I2C_DESIGNWARE_PLATFORM
being built-in. I2C_DESIGNWARE_PLATFORM is a visible symbol with
dependencies so in general the select should be avoided.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

A trivial function rename from wm8400_module_init to the name
wm8400_driver_init is also done to reduce possible confusion.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

Enric Balletbo i Serra 0545625baa mfd / platform: cros_ec_vbc: Instantiate only if the EC has a VBC NVRAM
The cros-ec-vbc driver is DT-only and there is a DT property that
indicates if the EC has the VCB NVRAM, in such case instantiate the
driver but don't instantiate on the other cases.

To do this move the check code to its parent instead of play with the
attribute group visibility. This changes a bit the actual behaviour.
Before the patch if an EC doesn't have a VBC NVRAM an empty vbc folder
is created in /sys/class/chromeos/<ec-device-name>, after the patch the
empty folder is not created, so, the folder is only created if the vbc
is set.

Sinan Kaya 9baddb61df mfd: Fix unmet dependency warning for MFD_TPS68470
After commit 5d32a66541 ("PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set") dependencies on CONFIG_PCI that previously were
satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly.

WARNING: unmet direct dependencies detected for I2C_DESIGNWARE_PLATFORM
  Depends on [n]: I2C [=y] && HAS_IOMEM [=y] && (ACPI [=y] && COMMON_CLK [=n] || !ACPI [=y])
  Selected by [y]:
  - MFD_TPS68470 [=y] && HAS_IOMEM [=y] && ACPI [=y] && I2C [=y]=y

MFD_TPS68470 is an ACPI only device and selects I2C_DESIGNWARE_PLATFORM.

I2C_DESIGNWARE_PLATFORM does not have any configuration today for ACPI
support without CONFIG_PCI set.

For sake of a quick fix this introduces a new mandatory dependency to
the driver which may survive without it. Otherwise we need to revisit
the driver architecture to address this properly.

Jonathan Hunter ac4ca4b9f4 mfd: tps6586x: Handle interrupts on suspend
The tps6586x driver creates an irqchip that is used by its various child
devices for managing interrupts. The tps6586x-rtc device is one of its
children that uses the tps6586x irqchip. When using the tps6586x-rtc as
a wake-up device from suspend, the following is seen:

 PM: Syncing filesystems ... done.
 Freezing user space processes ... (elapsed 0.001 seconds) done.
 OOM killer disabled.
 Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done.
 Disabling non-boot CPUs ...
 Entering suspend state LP1
 Enabling non-boot CPUs ...
 CPU1 is up
 tps6586x 3-0034: failed to read interrupt status
 tps6586x 3-0034: failed to read interrupt status

The reason why the tps6586x interrupt status cannot be read is because
the tps6586x interrupt is not masked during suspend and when the
tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is
seen before the i2c controller has been resumed in order to read the
tps6586x interrupt status.

The tps6586x-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent tps6586x interrupt.
However, the tps6586x-rtc driver cannot disable it's interrupt during
suspend otherwise we would never be woken up and so the tps6586x must
disable it's interrupt instead.

Prevent the tps6586x interrupt handler from executing on exiting suspend
before the i2c controller has been resumed by disabling the tps6586x
interrupt on entering suspend and re-enabling it on resuming from
suspend.

Revert the above patch, so the struct is allocated using kzalloc and we
have a release function for it that frees the allocated memory, otherwise
it is broken.

 ------------[ cut here ]------------
 Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

regulator: wm8994: Pass descriptor instead of GPIO number
Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.

There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.

The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d4846
"gpio: of: Support regulator nonstandard GPIO properties".

When trying to read any MC13892 ADC channel on a imx51-babbage board:

The MC13892 PMIC shutdowns completely.

After debugging this issue and comparing the MC13892 and MC13783
initializations done in the vendor kernel, it was noticed that the
CHRGRAWDIV bit of the ADC0 register was not being set.

This bit is set by default after power on, but the driver was
clearing it.

After setting this bit it is possible to read the ADC values correctly.

RaviChandra Sadineni 61cc15dac0 mfd: cros_ec: Check for mkbp events on resume only if supported.
Currently on every resume we check for mkbp events and notify the
clients. This helps in identifying the wakeup sources. But on devices
that do not support mkbp protocol, we might end up querying key state of
the keyboard in a loop which blocks the resume. Instead check for events
only if mkbp is supported.

Krzysztof Kozlowski eef0594aee mfd: sec-core: Allow building as module
The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module.  The dependent clock,
regulator and RTC drivers already can be built as a module.

Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.

This also add required module authors to sec-irq.c file based on recent
main contributors.

Linus Torvalds ca9eb48fe0 regulator: Regulator updates for next release
The biggest chunk of the regulator changes for this release outside of
 the new drivers is the conversion of the fixed regulator to use the GPIO
 descriptor API, there's a small addition to the GPIO API plus a bunch of
 updates to board files to implement it.  This is some really welcome
 work from Linus Walleij that's had a bunch of review and has been
 sitting in -next for a while so I'm fairly happy there's no major
 issues.
 
  - Helpers for overlapping linear ranges.
  - Display opmode and consumer requested load in the regualtor_summary
    file in debugfs, plus a fix there.
  - Support for the fun and entertaining power off mechanism that the
    pfuze100 hardware implements.
  - Conversion of the fixed regulator API to use GPIO descriptors,
    including pulling in a bunch of patches to a bunch of board files.
  - New drivers for Cirrus Logic Lochnagar, Qualcomm PMS405, Rohm
    BD71847, ST PMIC1, and TI LM363x devices.

It currently only works if the parent bus uses "simple-bus". We
currently try to probe children with non-existing compatible values.

the driver, so let's remove __init and __exit.

The IRQ work is added before the struct rtc is allocated and registered,
but this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.

Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before calling menelaus_add_irq_work.

Also, this solves a possible leak as the RTC is never released.

regmap: split up regmap_config.use_single_rw
Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.

Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

Linus Torvalds 99cc7ad46b Merge branch 'i2c/for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:

 - the core has now a lockless variant of i2c_smbus_xfer. Some open
   coded versions of this got removed in drivers. This also enables
   proper SCCB support in regmap.

 - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
   and we know use i2c_lock_bus() consistently with flags like
   I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.

 - the gpio fault injector got a new delicate testcase

 - the bus recovery procedure got fixed to handle the new testcase
   correctly

 - a new quirk flag for controllers not able to handle zero length
   messages together with driver updates to use it

 - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
   family S900

 - and a good set of driver improvements and bugfixes

In case of Device Tree platforms, even though the Samsung PMIC sec
device is instantiated from DT, the driver is still matched through I2C

alias instead of DT one.

This could change in the future so export DT module alias.

The AXP806 can operate in a standalone "self-working" mode, in which it
is also responsible for power control of the overall system. This mode
is similar to the master mode, but the EN/PWRON pin functions as a power

This patch adds code checking for the new "x-powers,self-working-mode"
property, and a separate mfd_cell list that includes the power button
(PEK) sub-device.

__usb_hcd_giveback_urb() and therefore it is required for the callback

The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

Charles Keepax f99fea9497 mfd: arizona: Don't use regmap_read_poll_timeout
Some Arizona CODECs have a small timing window where they will
NAK an I2C transaction if it happens before the boot done bit is
set. This can cause the read of the register containing the boot
done bit to fail until it is set. Since regmap_read_poll_timeout
will abort polling if a read fails it can't be reliably used to
poll the boot done bit over I2C.

Do a partial revert of ef84f885e0 ("mfd: arizona: Refactor
arizona_poll_reg"), removing the regmap_read_poll_timeout but
leaving the refactoring to make the arizona_poll_reg take more
sensible arguments.

platform/chrome: Move cros-ec transport drivers to drivers/platform.
There are some cros-ec transport drivers (I2C, SPI) living in MFD, while
others (LPC) living in drivers/platform. The transport drivers are more
platform specific. So, move the I2C and SPI transport drivers to the
platform/chrome directory. The patch also removes the MFD_ prefix of
their Kconfig symbols.

Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

It is not mandatory that platform data is passed along the ac97

This is for example the case for the PXA zylonite platform, so fix the

Linus Torvalds 68cc38ff33 regulator: Updates for v4.18
Quite a lot of core work this time around, though not 100% successful.
 
 We gained support for runtime mode changes thanks to David Collins and
 improved support for write only regulators (ones where we can't read
 back the configuration) from Douglas Anderson.
 
 There's been quite a bit of work from Linus Walleij on converting from
 specfying GPIOs by numbers to descriptors.  Sadly the testing turned out
 to be less good than we had hoped and so a lot of this had to be
 reverted.
 
 We also have the start of updates to use coupled regulators from Maciej
 Purski, unfortunately there are further problems there so the last
 couple of patches have been reverted.
 
 We also have new drivers for BD71837 and SY8106A devices, SAW regulators
 on Qualcomm SPMI and dropped support for some preproduction chips
 that never made it to market from the AB8500 driver.

Linus Torvalds ea125dedbc This is the bulk of GPIO changes for the v4.18 development
cycle.
 
 Core changes:
 
 - We have killed off VLA from the core library and all drivers.
   The background should be clear for everyone at this point:
   https://lwn.net/Articles/749064/
   Also I just don't like VLA's, kernel developers hate it when
   compilers do things behind their back. It's as simple as that.
   I'm sorry that they even slipped in to begin with.
   Kudos to Laura Abbott for exorcising them.
 
 - Support GPIO hogs in machines/board files.
 
 New drivers and chip support:
 
 - R-Car r8a77470 (RZ/G1C)
 - R-Car r8a77965 (M3-N)
 - R-Car r8a77990 (E3)
 - PCA953x driver improvements to accomodate more variants.
 
 Improvements and new features:
 
 - Support one interrupt per line on port A in the DesignWare
   dwapb driver.
 
 Misc:
 
 - Random cleanups, right header files in the drivers, some
   size optimizations etc.

Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

   - Introduce arithmetic overflow test helper functions (Rasmus)

   - Use overflow helpers in 2-factor allocators (Kees, Rasmus)
