Pull thermal managament updates from Zhang Rui:
- Enhance thermal "userspace" governor to export the reason when a
thermal event is triggered and delivered to user space. From Srinivas
Pandruvada
- Introduce a single TSENS thermal driver for the different versions of
the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
msm8916, msm8960, msm8974 and msm8996 families is also added. From
Rajendra Nayak
- Introduce hardware-tracked trip points support to the device tree
thermal sensor framework. The framework supports an arbitrary number
of trip points. Whenever the current temperature is changed, the trip
points immediately below and above the current temperature are found,
driver callback is invoked to program the hardware to get notified
when either of the two trip points are triggered. Hardware-tracked
trip points support for rockchip thermal driver is also added at the
same time. From Sascha Hauer, Caesar Wang
- Introduce a new thermal driver, which enables TMU (Thermal Monitor
Unit) on QorIQ platform. From Jia Hongtao
- Introduce a new thermal driver for Maxim MAX77620. From Laxman
Dewangan
- Introduce a new thermal driver for Intel platforms using WhiskeyCove
PMIC. From Bin Gao
- Add mt2701 chip support to MTK thermal driver. From Dawei Chien
- Enhance Tegra thermal driver to enable soctherm node and set
"critical", "hot" trips, for Tegra124, Tegra132, Tegra210. From Wei

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.9 series:
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"

Added one additional parameter to thermal_zone_device_update() to provide
caller with an optional capability to specify reason.
Currently this event is used by user space governor to trigger different
processing based on event code. Also it saves an additional call to read
temperature when the event is received.
The following events are cuurently defined:
- Unspecified event
- New temperature sample
- Trip point violated
- Trip point changed
- thermal device up and down
- thermal device power capability changed

drms_uA_update() always returns failure when it cannot find regulator's
input voltage. But if hardware supports load configuration with
ops->set_load() and the input regulator isn't specified with valid reason
such as the input regulator is battery, not finding input voltage is
normal so such case should not return with an error.
Avoid such inadequate error return by checking input/output voltages
only when drms_uA_update() is about to configure load with enum based
ops->set_mode().

http://www.ti.com/lit/pdf/SWCZ010:
DCDC o/p voltage can go higher than programmed value
Impact:
VDDI, VDD2, and VIO output programmed voltage level can go higher than
expected or crash, when coming out of PFM to PWM mode or using DVFS.
Description:
When DCDC CLK SYNC bits are 11/01:
* VIO 3-MHz oscillator is the source clock of the digital core and input
clock of VDD1 and VDD2
* Turn-on of VDD1 and VDD2 HSD PFETis synchronized or at a constant
phase shift
* Current pulled though VCC1+VCC2 is Iload(VDD1) + Iload(VDD2)
* The 3 HSD PFET will be turned-on at the same time, causing the highest
possible switching noise on the application. This noise level depends
on the layout, the VBAT level, and the load current. The noise level
increases with improper layout.
When DCDC CLK SYNC bits are 00:
* VIO 3-MHz oscillator is the source clock of digital core
* VDD1 and VDD2 are running on their own 3-MHz oscillator
* Current pulled though VCC1+VCC2 average of Iload(VDD1) + Iload(VDD2)
* The switching noise of the 3 SMPS will be randomly spread over time,
causing lower overall switching noise.
Workaround:
Set DCDCCTRL_REG[1:0]= 00.

The new op is analogous to set_voltage_time_sel. It can be used by
regulators which don't have a table of discrete voltages. The function
returns the time for the regulator output voltage to stabilize after
being set to a new value, in microseconds. If the op is not set a
default implementation is used to calculate the delay.
This change also removes the ramp_delay calculation in the PWM
regulator, since the driver now uses the core code for the calculation
of the delay.

The current code assumes that only the ramp_delay is used to determine
the time needed for the voltage to stabilize. This may be true for the
calculation done by regulator_set_voltage_time_sel(), however regulators
can implement their own set_voltage_time_sel() op which would be skipped
if no ramp delay is specified. Remove the check in
_regulator_do_set_voltage(), the functions calculating the ramp delay
return 0 anyway when the ramp delay is not configured.

differing step sizes and the pma8084 ftsmps supports two. These

respectively. Port these ranges over to the RPM SMD regulator

The continuous mode allows one to declare a PWM regulator without having
to declare the voltage <-> dutycycle association table. It works fine as
long as your voltage(dutycycle) function is linear, but also has the
following constraints:
- dutycycle for min_uV = 0%
- dutycycle for max_uV = 100%
- dutycycle for min_uV < dutycycle for max_uV
While the linearity constraint is acceptable for now, we sometimes need to
restrict of the PWM range (to limit the maximum/minimum voltage for
example) or have a min_uV_dutycycle > max_uV_dutycycle (this could be
tweaked with PWM polarity, but not all PWMs support inverted polarity).
Add the pwm-dutycycle-range and pwm-dutycycle-unit DT properties to define
such constraints. If those properties are not defined, the PWM regulator
use the default pwm-dutycycle-range = <0 100> and
pwm-dutycycle-unit = <100> values (existing behavior).

This fix alters the minimum and maximum BUCK voltage limits for DA9052 and
DA9053. It does so for the following cases:
DA9052
- BUCK3 (MEM)
min: 0.925V -> 0.950V
max: 2.500V -> 2.525V
DA9053
- BUCK3 (MEM)
min: 0.925V -> 0.950V
max: 2.500V -> 2.525V
- BUCK4 (PERI)
min: 0.925V -> 0.950V
max: 2.500V -> 2.525V
The voltage range remains the same, but the limits are shifted by +0.025V.
This change is provided on DA9052:MEM, DA9053:MEM and DA9053:PERI
and is a voltage difference of 0.025V, compared to those measured before
this fix is applied. The patch has the effect of decreasing *all* measured
voltages on those BUCKs when compared against the previously measured
values for the same software voltage request.
For example, with this fix applied for DA9052:MEM, DA9053:MEM and
DA9053:PERI, the following is true.
Because the previous software defined slot 0 as being 0.925V, if a request
for 0.950V was previously sent, the slot 1 voltage would have been used.
This would have corresponded to an actual measured voltage of 0.975V. But,
with this patch fix, and with slot 0 properly aligned to 0.950V, if a
voltage of 0.950V is requested by software, a measured value of 0.950V will
be provided.

The MT6323 is a regulator found on boards based on MediaTek MT7623 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

Addition of device tree support for DA9210.
Two files are modified, the driver source file and the binding document.
Updates for the regulator source file include an .of_match_table entry and
node match checking in the probe() function for a compatible da9210 string.
Minor binding documentation changes have been made to the title and the
example.

This node pointer is returned by of_get_child_by_name() with
refcount incremented in this function. of_node_put() is missing
when exitting this function while invalid device type. Fix it
by move of_get_child_by_name() code after device type check.

There is only one instance of ab8500_regulator_platform_data, and it's
safe to assume we won't ever merge another one, so it's rather pointless
to pass it through multiple levels of platform data pointers.
This moves the structure and everything referenced by it into the
driver that uses it.

The pm8x41_hfsmps ranges overlap. The first range is from 375000
to 1562500:
375000 + (95 * 12500) == 1562500
and the second range starts at 1550000. Interestingly, the second
range ends at the correct value when it's set to be the
appropriate start value, 1575000:
1575000 + ((158 - 96) * 25000) == 3125000

The continuous PWM voltage regulator is caching the voltage value in
the ->volt_uV field. While most of the time this value should reflect the
real voltage, sometime it can be sightly different if the PWM device
rounded the set_duty_cycle request.
Moreover, this value is not valid until someone has modified the regulator
output.
Remove the ->volt_uV field and always rely on the PWM state to calculate
the regulator output.
