Add support for the rk809 and rk817 regulator driver.
Their specifications are as follows：
1. The RK809 and RK809 consist of 5 DCDCs, 9 LDOs
and have the same registers for these components except dcdc5.
2. The dcdc5 is a boost dcdc for RK817 and is a buck for RK809.
3. The RK817 has one switch but The Rk809 has two.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338
and BCM6345.
- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns.

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

"This is the bulk of GPIO changes for kernel v4.6. There is quite a

essentially a part of the GPIO subsystem so it should not be needed.

The driver depends on MFD_STW481X but there isn't a build dependency so
it's a good idea to allow the driver to always be built when the

That way, the driver can be built with a config generated by make
allyesconfig and check if a patch would break the build.

The main thing this time around is support for suspend mode
configuration from DT which will enable some very useful power savings
on systems where we can't rely on the bootloader configuration. We
still don't really support dynamic configuration of this at runtime,
that may come later if there is any demand.
- Support for specifying the target regulation mode and voltage during
system suspend via DT, enabling power savings in that mode.
- Reduce the default verbosity of the logging on boot, improving boot
times especially for systems with very large numbers of regulators.
- Lots of cleanups and fixes for Maxim PMIC drivers.
- New driver for Richtek RT5033.

The bulk of the changes for this release are a few new drivers however
there are a couple of noticable core changes and the usual stream of
cleanups and fixes:
- Move disable of unused regulators later in init so it comes after
deferred probe has iterated making startup smoother.
- Fixes reference counting of the DT nodes for constraints from Charles
Keepax. This has little practical impact since all real users of
the regulator bindings use FDT which doesn't need the reference
counting.
- Lots of cleanups, especially to the Samsung drivers.
- Support for Linear Technologies LTC3589, Texas Instruments TPS658640

On some STMicroelectronics hardware reside regulators consisting
partly of a PWM input connected to the feedback loop. As the PWM
duty-cycle is varied the output voltage adapts. This driver
allows us to vary the output voltage by adapting the PWM input
duty-cycle.

Add support for S2MPS14 PMIC regulators to s2mps11 driver. The S2MPS14
has fewer BUCK-s and LDO-s than S2MPS11. It also does not support
controlling the BUCK ramp delay.

A respin of the merges in the previous pull request with one extra fix.
A quiet release for the regulator API, quite a large number of small
improvements all over but other than the addition of new drivers for the
AS3722 and MAX14577 there is nothing of substantial non-local impact.

MAX14577 chip is a multi-function device which includes MUIC,
charger and voltage regulator. The driver is located in drivers/mfd.
This patch adds regulator driver for MAX14577 chip. There are two
regulators in this chip:
1. Safeout LDO with constant voltage output of 4.9V. It can be only
enabled or disabled.
2. Current regulator for the charger. It provides current from 90mA up
to 950mA.
Driver supports Device Tree.

When a system has said that it has fully specified constraints for its
regulators it is still possible that some supplies may be missing,
especially if regulator support has been added to a driver after the
board was integrated. We can handle such situations more gracefully by
providing a dummy regulator.
Unless the caller has specifically indicated that the system design may
not include a given regulator by using regulator_get_optional() or that
it needs its interactions to have an effect using regulator_get_exclusive()
provide a dummy regulator if we can't locate a real one.
The kconfig option REGULATOR_DUMMY that provided similar behaviour for all
regulators has been removed, systems that need it should flag that they
have full constraints instead.
