The maximum supported voltage for ldo_io# is 3.3V, but on cold
boot the selector comes up at 0x1f, which maps to 3.8V.
This causes _regulator_get_voltage() to fail with -EINVAL which
causes regulator registration to fail when constrains are used:
[ 1.467788] vcc-touchscreen: failed to get the current voltage(-22)
[ 1.474209] axp20x-regulator axp20x-regulator: Failed to register ldo_io1
[ 1.483363] axp20x-regulator: probe of axp20x-regulator failed with error -22
This commits makes the axp20x regulator driver accept the 0x1f register
value, fixing this.
The datasheet does not guarantee reliable operation above 3.3V, so on
boards where this regulator is used the regulator-max-microvolt setting
must be 3.3V or less.

The minium voltage of 1800mV is a copy and paste error from the axp20x
regulator info. The correct minimum voltage for the ldo_io regulators
on the axp22x is 700mV.

The current linear voltage range for the LDO4 regulator found in the APX20X
PMICs assumes that the voltage is linear between 2.5 and 3.1V.
However, the PMIC can output up to 3.3V on that regulator by skipping the
2.6V and 2.9V steps.
Fix the ranges to read and set the proper voltages.

The buck9 regulator of S2MPS11 PMIC had incorrect vsel_mask (0xff
instead of 0x1f) thus reading entire register as buck9's voltage. This
effectively caused regulator core to interpret values as higher voltages
than they were and then to set real voltage much lower than intended.
The buck9 provides power to other regulators, including LDO13
and LDO19 which supply the MMC2 (SD card). On Odroid XU3/XU4 the lower
voltage caused SD card detection errors on Odroid XU3/XU4:
mmc1: card never left busy state
mmc1: error -110 whilst initialising SD card
During driver probe the regulator core was checking whether initial
voltage matches the constraints. With incorrect vsel_mask of 0xff and
default value of 0x50, the core interpreted this as 5 V which is outside
of constraints (3-3.775 V). Then the regulator core was adjusting the
voltage to match the constraints. With incorrect vsel_mask this new
voltage mapped to a vere low voltage in the driver.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel v4.6. There is quite a
lot of interesting stuff going on.
The patches to other subsystems and arch-wide are ACKed as far as
possible, though I consider things like per-arch <asm/gpio.h> as
essentially a part of the GPIO subsystem so it should not be needed.
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
- X-Gene (ARM64) standby GPIO controller"

At boot time the regulator driver can be initialized before the
gpio, in which case the call to of_get_named_gpio will return
EPROBE_DEFER. This value is silently passed to regulator_register
which will return success, although the gpio is not registered
(regulator_ena_gpio_request not called) as the value passed is
detected as invalid. The gpio_regulator_probe will therefore
succeed win no gpio requested.

This problem was introduced by:
commit daad134d6649 ("regulator: core: Request GPIO before creating
sysfs entries")
The error path was not updated correctly after moving GPIO registration
code and in case regulator_ena_gpio_free failed, device_unregister() was
called even though device_register() was not yet called.
This problem breaks the boot at least on all Tegra 32-bit devices. It
will also crash each device that specifices GPIO that is unavaiable at
regulator_register call. Here's error log I've got when forced GPIO to
be invalid:

regulator_attr_is_visible (which is a .is_visible callback of
regulator_dev_group attribute_grpup) checks rdev->ena_pin to decide if
"status" file should be present in sysfs. This field is set at the end
of regulator_ena_gpio_request so it has to be called before
device_register() otherwise this test will always fail, causing "status"
file to not be visible.
Since regulator_attr_is_visible also tests for is_enabled() op, this
problem is only visible for regulators that does not define this
callback, like regulator-fixed.c.

i2c_master_send() returns the number of bytes written on success.
So current code returns 2 if ad5398_write_reg() success.
This return value is propagated to .set_current_limit, .enable and .disable
callbacks of regulator_ops. This can be a problem, for example, if the
users test if the return value of regulator_set_current_limit() is 0.
Fix it by making ad5398_write_reg() return 0 on success.

The s5m8767_pmic_probe() function calls s5m8767_get_register() to
read data without checking the return code, which produces a compile-time
warning when that data is accessed:
drivers/regulator/s5m8767.c: In function 's5m8767_pmic_probe':
drivers/regulator/s5m8767.c:924:7: error: 'enable_reg' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/regulator/s5m8767.c:944:30: error: 'enable_val' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes the s5m8767_get_register() function to return a -EINVAL
not just for an invalid register number but also for an invalid
regulator number, as both would result in returning uninitialized
data. The s5m8767_pmic_probe() function is then changed accordingly
to fail on a read error, as all the other callers of s5m8767_get_register()
already do.
In practice this probably cannot happen, as we don't call
s5m8767_get_register() with invalid arguments, but the gcc
warning seems valid in principle, in terms writing safe
error checking.

Originally the helper macros used uppercase regulator names, which
are primarily used to expand to the regulator ID enum, as the default
names. This is aestheticly unpleasent.
Since the of_match bits are the same, just lowercase, use that as the
default names instead.

It's perfectly valid to use the LTC3589 without an interrupt pin
connected to it. Currently, the driver probing fails when client->irq
is 0 (which means "no interrupt"). Don't register the interrupt
handler in that case but successfully finish the device probing instead.

The max77686 and max77802 regulator drivers are for sub-devices of a MFD
driver for some PMIC blocks. But the same object file name (max77686.o)
was used for both the common MFD driver and the max77686 regulator one.
This confuses kbuild if both drivers are built as module causing the MFD
driver to not be copied when installing the modules.
Also, max77{686,802} are a quite generic name for MFD subdevices drivers
so it is better to rename them to max77{686,802}-regulator like it's the
case for most regulator drivers.

The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.

This patch adds support for TPS65912 PMIC regulators.
The regulators set consists of 4 DCDCs and 10 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.
