When the thermal subsystem is a loadable module, the u8500 driver
fails to build:drivers/thermal/built-in.o: In function `db8500_thermal_probe':
db8500_thermal.c:(.text+0x96c): undefined reference to `thermal_zone_device_register'
drivers/thermal/built-in.o: In function `db8500_thermal_work':
db8500_thermal.c:(.text+0xab4): undefined reference to `thermal_zone_device_update'This changes the symbol to a tristate, so Kconfig can track the
dependency correctly.Signed-off-by: Arnd Bergmann

Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better
reflect the fact that this is not the GPIO struct device
abstraction. We will add that soon so this would be totallt
confusing.- It was noted that the driver .get_value() callbacks was sometimes
reporting negative -ERR values to the gpiolib core, expecting them
to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than
zero" to indicate that a line was active. As some would have bit
31 set to indicate "line active" it clashed with negative error
codes. This is fixed by the largeish series clamping values in all
drivers with !!value to [0,1] and then augmenting the code to
propagate error codes to consumers. (Includes some ACKed patches
in other subsystems.)- Add a void *data pointer to struct gpio_chip. The container_of()
design pattern is indeed very nice, but we want to reform the
struct gpio_chip to be a non-volative, stateless business, and keep
states internal to the gpiolib to be able to hold on to the state
when adding a proper userspace ABI (character device) further down
the road. To achieve this, drivers need a handle at the internal
state that is not dependent on their struct gpio_chip() so we add
gpiochip_add_data() and gpiochip_get_data() following the pattern
of many other subsystems. All the "use gpiochip data pointer"
patches transforms drivers to this scheme.- The Generic GPIO chip header has been merged into the general
header, and the custom header for that
removed. Instead of having a separate mm_gpio_chip struct for
these generic drivers, merge that into struct gpio_chip,
simplifying the code and removing the need for separate and
confusing includes.Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.- Incremental driver features for PXA, PCA953X, Lantiq (patches from
the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
but the branch is merged here too to account for infrastructural
changes).- The sx150x driver now supports the sx1502"

Pull oower management and ACPI updates from Rafael Wysocki:
"As far as the number of commits goes, ACPICA takes the lead this time,
followed by cpufreq and the device properties framework changes.The most significant new feature is the debugfs-based interface to the
ACPICA's AML debugger added in the previous cycle and a new user space
tool for accessing it.On the cpufreq front, the core is updated to handle governors more
efficiently, particularly on systems where a single cpufreq policy
object is shared between multiple CPUs, and there are quite a few
changes in drivers (intel_pstate, cpufreq-dt etc).The device properties framework is updated to handle built-in (ie
included in the kernel itself) device properties better, among other
things by adding a fallback mechanism that will allow drivers to
provide default properties to be used in case the plaform firmware
doesn't provide the properties expected by them.The Operating Performance Points (OPP) framework gets new DT bindings
and debugfs support.A new cpufreq driver for ST platforms is added and the ACPI driver for
AMD SoCs will now support the APM X-Gene ACPI I2C device.The rest is mostly fixes and cleanups all over.
Specifics:
- Add a debugfs-based interface for interacting with the ACPICA's AML
debugger introduced in the previous cycle and a new user space tool
for that, fix some bugs related to the AML debugger and clean up
the code in question (Lv Zheng, Dan Carpenter, Colin Ian King,
Markus Elfring).- Update ACPICA to upstream revision 20151218 including a number of
fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe
Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael
Wysocki).In particular, the previously added erroneous support for the _SUB
object is dropped, the concatenate operator will support all ACPI
objects now, the Debug Object handling is improved, the SuperName
handling of parameters being control methods is fixed, the
ObjectType operator handling is updated to follow ACPI 5.0A and the
handling of CondRefOf and RefOf is updated accordingly, module-
level code will be executed after loading each ACPI table now
(instead of being run once after all tables containing AML have
been loaded), the Operation Region handlers management is updated
to fix some reported problems and a the ACPICA code in the kernel
is more in line with the upstream now.- Update the ACPI backlight driver to provide information on whether
or not it will generate key-presses for brightness change hotkeys
and update some platform drivers (dell-wmi, thinkpad_acpi) to use
that information to avoid sending double key-events to users pace
for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu,
Adrien Schildknecht).- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
- Fix the handling of the list of device IDs of device objects found
in the ACPI namespace and add a helper for checking if there is a
device object for a given device ID (Lukas Wunner).- Change the logic in the ACPI namespace scanning code to create
struct acpi_device objects for all ACPI device objects found in the
namespace even if _STA fails for them which helps to avoid device
enumeration problems on Microsoft Surface 3 (Aaron Lu).- Add support for the APM X-Gene ACPI I2C device to the ACPI driver
for AMD SoCs (Loc Ho).- Fix the long-standing issue with the DMA controller on Intel SoCs
where ACPI tables have no power management support for the DMA
controller itself, but it can be powered off automatically when the
last (other) device on the SoC is powered off via ACPI and clean up
the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts
to fix that problem (Andy Shevchenko).- Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
Sinan Kaya).- Update the device properties framework for better handling of
built-in properties, add support for built-in properties to the
platform bus type, update the MFD subsystem's handling of device
properties and add support for passing default configuration data
as device properties to the intel-lpss MFD drivers, convert the
designware I2C driver to use the unified device properties API and
add a fallback mechanism for using default built-in properties if
the platform firmware fails to provide the properties as expected
by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus,
Andrew Morton).- Add new Device Tree bindings to the Operating Performance Points
(OPP) framework and update the exynos4412 DT binding accordingly,
introduce debugfs support for the OPP framework (Viresh Kumar,
Bartlomiej Zolnierkiewicz).- Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng
Chen).- Update the cpufreq core to make the handling of governors more
efficient, especially on systems where policy objects are shared
between multiple CPUs (Viresh Kumar, Rafael Wysocki).- Fix cpufreq governor handling on configurations with
CONFIG_HZ_PERIODIC set (Chen Yu).- Clean up the cpufreq core code related to the boost sysfs knob
support and update the ACPI cpufreq driver accordingly (Rafael
Wysocki).- Add a new cpufreq driver for ST platforms and corresponding Device
Tree bindings (Lee Jones).- Update the intel_pstate driver to allow the P-state selection
algorithm used by it to depend on the CPU ID of the processor it is
running on, make it use a special P-state selection algorithm (with
an IO wait time compensation tweak) on Atom CPUs based on the
Airmont and Silvermont cores so as to reduce their energy
consumption and improve intel_pstate documentation (Philippe
Longepe, Srinivas Pandruvada).- Update the cpufreq-dt driver to support registering cooling devices
that use the (P * V^2 * f) dynamic power draw formula where V is
the voltage, f is the frequency and P is a constant coefficient
provided by Device Tree and update the arm_big_little cpufreq
driver to use that support (Punit Agrawal).- Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob
Tanenbaum, Markus Elfring).- cpuidle core tweaks related to polling and measured_us calculation
(Rik van Riel).- Removal of modularity from a few cpuidle drivers (clps711x, ux500,
exynos) that cannot be built as modules in practice (Paul
Gortmaker).- PM core update to prevent devices from being probed during system
suspend/resume which is generally problematic and may lead to
inconsistent behavior (Grygorii Strashko).- Assorted updates of the PM core and related code (Julia Lawall,

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.Cc: Lee Jones

Add device tree bindings to support specifying outputs from the chip as
mono outputs. Whilst we are doing it change the out_mono pdata from a
bool to an int, because Sparse gets upset about using ARRAY_SIZE on
bools.Signed-off-by: Charles Keepax

Allow support for the DA9063 PMIC to be modular, cfr. DA9062, which
allows to decrease size of multi-platform kernels (e.g.
multi_v7_defconfig).Signed-off-by: Geert Uytterhoeven

Currently the driver requests the boot done and control interface IRQs
before it has requested its own IRQ line. This can cause problems on
edge triggered IRQ systems as if an edge occurs before the parent IRQ is
enabled it will be missed. Whilst we are changing the error handling
remove an unused label as well.Signed-off-by: Charles Keepax

The newly introduced as3722_i2c_suspend/resume functions are built
unconditionally, but only used when power management is enabled,
so we get a warning otherwise:drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function]
drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function]This marks them both as __maybe_unused, which avoids an ugly #ifdef
and gives us best compile-time coverage. When they are unused, the
compiler will silently drop the functions from its output.Signed-off-by: Arnd Bergmann

These new helpers simplify implementing multi-driver modules and
properly handle failure to register one driver by unregistering all
previously registered drivers.Signed-off-by: Thierry Reding

Revision ID registers are available only on devices with
Slave IDs that are even, so don't make access to unavailable

wm831x_unique_id_show currently displays an interesting pattern of '0'
and '3' characters which isn't very useful (figuring out why is left
as an exercise for the reader). Presumably "buf[i]" should have been
"id[i] & 0xff".But while there, it is much simpler to simply use %phN and do all the
formatting at once.Signed-off-by: Rasmus Villemoes

Currently syscon has a fixed configuration of 32 bits for register and
values widths. In some cases, it would be desirable to be able to
customize the value width.For example, certain boards (like the ones manufactured by Technologic
Systems) have a FPGA that is memory-mapped, but its registers are only
16-bit wide.This patch adds an optional "reg-io-width" DT binding for syscon that
allows to change the width for the data bus (i.e. val_bits). If this
property is provided, it will also set the register stride to
reg-io-width's value. If not provided, the default configuration is
used.Signed-off-by: Damien Riegel
