Linus Torvalds ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
 
 Misc:
 - Replace all kthread usages with simple works

In  tegra based platform which uses MAX20024 pmic, when
some of regulators are configured FPS_NONE(flexible power sequencer)
causes PMIC GPIO1 to go low which lead to various other rails turning off,
to avoid this MPOK bit of those regulators need to be set to 0

Jisheng Zhang 09f2ba0b0b regulator: gpio: properly check return value of of_get_named_gpio
The function of_get_named_gpio() could return -ENOENT, -EPROBE_DEFER
-EINVAL and so on. Currently, for the optional property "enable-gpio",
we only check -EPROBE_DEFER, this is not enough since there may be
misconfigured "enable-gpio" in the DTB, of_get_named_gpio() will return
-EINVAL in this case, we should return immediately here. And for the
optional property "gpios", we didn't check the return value, the driver
will continue to the point where gpio_request_array() is called, it
doesn't make sense to continue if we got -EPROBE_DEFER or -EINVAL here.

This patch tries to address these two issues by properly checking the
return value of of_get_named_gpio.

Chen-Yu Tsai 618c808968 regulator: axp20x: Fix axp809 ldo_io registration error on cold boot
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 was previously
corrected by Allwinner's U-boot, which set all regulators on the PMICs
to some pre-configured voltage. With recent progress in U-boot SPL
support, this is no longer the case. In any case we should handle
this quirk in the kernel driver as well.

This invalid setting causes _regulator_get_voltage() to fail with -EINVAL
which causes regulator registration to fail when constrains are used:

[    1.054181] vcc-pg: failed to get the current voltage(-22)
[    1.059670] axp20x-regulator axp20x-regulator.0: Failed to register ldo_io0
[    1.069749] axp20x-regulator: probe of axp20x-regulator.0 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.

This is essentially the same as the commit f40d4896bf ("regulator:
axp20x: Fix axp22x ldo_io registration error on cold boot") for AXP22x
PMICs.

The handling of bypass_val_on that was added in
regulator_get_bypass_regmap is done unconditionally however
several drivers don't define a value for bypass_val_on. This
results in those drivers reporting bypass being enabled when
it is not. In regulator_set_bypass_regmap we use bypass_mask
if bypass_val_on is zero. This patch adds similar handling in

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
   Ni

 - Add resume support for tango thermal driver. From Marc Gonzalez

Linus Torvalds 6a497e9d58 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.

Srinivas Pandruvada 0e70f466fb thermal: Enhance thermal_zone_device_update for events
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

Baoyou Xie 5258beedc3 regulator: dbx500: remove unused functions in dbx500-prcmu.c
We get 2 warnings when building kernel with W=1:
drivers/regulator/dbx500-prcmu.c:78:6: warning: no previous prototype for 'ux500_regulator_suspend_debug' [-Wmissing-prototypes]
drivers/regulator/dbx500-prcmu.c:87:6: warning: no previous prototype for 'ux500_regulator_resume_debug' [-Wmissing-prototypes]

In fact, these functions are unused in
dbx500-prcmu.c, but should be removed.

So this patch removes the unused functions.

Eric Jeong 5ff00f6aa8 regulator: pv88080: Update regulator for PV88080 BB silicon support
Three files are modified, the driver, header file and the binding document.

Updates for the regulator source file include and .of_match_table entry
and node match checking in the probe() function for a compatible pv88080
silicon type. A new "HVBUCK" is added in source file and added
regsiter definition in header file for pv88080 bb silicion.
The binding documentation changes have been made to reflect these updates.

Joonwoo Park 577766175c regulator: core: don't return error with inadequate reason
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().

Jan Remmet 8f9165c981 regulator: tps65910: Work around silicon erratum SWCZ010
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.

Matthias Kaehlcke 73e705bf81 regulator: core: Add set_voltage_time op
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.

Matthias Kaehlcke d89564efe7 regulator: core: Don't skip set_voltage_time when ramp delay disabled
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.

Matthias Kaehlcke 31dfe686ed regulator: core: Simplify error flow in _regulator_do_set_voltage()
If the voltage can not be set jump to the end of the function. This
avoids having to check for an error multiple times and eliminates one
level of nesting in a follow-up change.
