c1d1e91aff platform/chrome: mfd/cros_ec_dev: Add sysfs entry to set keyboard wake lid angle
This adds a sysfs attribute (/sys/class/chromeos/cros_ec/kb_wake_angle)
used to set and get the keyboard wake lid angle. This attribute is
present only if 2 accelerometers are controlled by the EC.

This patch also moves the cros_ec features check before the device is
added so the features map obtained from the EC is ready on time.

fbe173e3ff Merge tag 'rtc-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
 "This contains a few series that have been in preparation for a while
  and that will help systems with RTCs that will fail in 2038, 2069 or
  2100.

  Subsystem:
   - Add tracepoints
   - Rework of the RTC/nvmem API to allow drivers to discard struct
     nvmem_config after registration
   - New range API, drivers can now expose the useful range of the RTC
   - New offset API the core is now able to add an offset to the RTC
     time, modifying the supported range.
   - Multiple rtc_time64_to_tm fixes
   - Handle time_t overflow on 32 bit platforms in the core instead of
     letting drivers do crazy things.
   - remove rtc_control API

  New driver:
   - Intersil ISL12026

  Drivers:
   - Drivers exposing the RTC non volatile memory have been converted to
     use nvmem
   - Removed useless time and date validation
   - Removed an indirection pattern that was a cargo cult from ancient
     drivers
   - Removed VLA usage
   - Fixed a possible race condition in probe functions
   - AB8540 support is dropped from ab8500
   - pcf85363 now has alarm support"

df34df483a Merge tag 'staging-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO updates from Greg KH:
 "Here is the big set of Staging/IIO driver patches for 4.17-rc1.

  It is a lot, over 500 changes, but not huge by previous kernel release
  standards. We deleted more lines than we added again (27k added vs.
  91k remvoed), thanks to finally being able to delete the IRDA drivers
  and networking code.

  We also deleted the ccree crypto driver, but that's coming back in
  through the crypto tree to you, in a much cleaned-up form.

  Added this round is at lot of "mt7621" device support, which is for an
  embedded device that Neil Brown cares about, and of course a handful
  of new IIO drivers as well.

  And finally, the fsl-mc core code moved out of the staging tree to the
  "real" part of the kernel, which is nice to see happen as well.

  Full details are in the shortlog, which has all of the tiny cleanup
  patches described.

  All of these have been in linux-next for a while with no reported
  issues"

Jonathan writes:

First round of new devices, features and cleanups for IIO in the 4.17 cycle.

Outside of IIO
* Strongly typed 64bit int_sqrt function needed by the mlx90632

New device support
* adc081s
  - New driver supporting adc081s, adc101s and adc121s TI ADCs.
* ad5272
  - New driver supproting the ad5272 and ad5274 ADI digital potentiometers
    with DT bindings.
* axp20x_adc
  - support the AXP813 ADC - includes rework patches to prepare for this.
* mlx90632
  - New driver with dt bindings for this IR temperature sensor.

* axp20x_adc
  - Add DT bindings and probing.
* dht11
  - The sensor has a wider range than advertised in the datasheet - support it.
* st_lsm6dsx
  - Add hardware timestamp su9pport.

Cleanups
* ABI docs
  - Update email contact for Matt Ranostay
* SPDX changes
  - Matt Ranostay has moved his drivers over to SPDX.  Currently we are making
    this an author choice in IIO.
* ad7192
  - Disable burnout current on misconfiguration.  No actually effect as
    they simply won't work otherwise.
* ad7476
  - Drop a license definition that was replicating information in SPDX tag.
* ade7758
  - Expand buf_lock to cover both buffer and state protection allowing
    unintented uses of mlock in the core to be removed.
* ade7759
  - Align parameters to opening parenthesis.
* at91_adc
  - Depend on sysfs instead of selecting it - for try wide consistency.
* ccs811
  - trivial naming type for a define.
* ep93xx
  - Drop a redundant return as a result checking platform_get_resource.
* hts221
  - Regmap conversion which simplifies the driver somewhat.
  - Clean up some restricted endian cast warnings.
  - Drop a trailing whitespace from a comment
  - Drop an unnecessary get_unaligned by changing to the right 16bit data type.
* ms5611
  - Fix coding style in the probe function (whitespace)
* st_accel
  - Use strlcpy instead of strncpy to avoid potentially truncating a string.

When setting up a fixed regulator on the DA9055, pass a descriptor
instead of a global GPIO number. This facility is not used in the

1a3f675564 iio: adc: axp20x_adc: add support for AXP813 ADC
The X-Powers AXP813 PMIC is really close to what is already done for
AXP20X/AXP22X.

There are two pairs of bits to set the rate (one for Voltage and Current
measurements and one for TS/GPIO0 voltage measurements) instead of one.

The register to set the ADC rates is different from the one for
AXP20X/AXP22X.

GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X.

The scales to apply to the different inputs are unlike the ones from
AXP20X and AXP22X.

b860b419d9 mfd: Fix RTS5227 (and others) powermanagement
Commit 8275b77a15 ("mfd: rts5249: Add support for RTS5250S power
saving") adds powersaving support for device-ids 5249 524a and 525a.

But as a side effect it breaks ASPM support for all the other device-ids,
causing e.g. the Haswell CPU on a Lenovo T440s to not go into a higher
c-state then PC3, while previously it would go to PC7, causing the
machine to idle at 7.4W instead of 6.6W!

The problem here is the new option.dev_aspm_mode field, which only gets
explicitly initialized in the new code for the device-ids 5249 524a and
525a. Leaving the dev_aspm_mode 0 for the other device-ids.

The default dev_aspm_mode 0 is mapped to DEV_ASPM_DISABLE, but the
old behavior of calling rtsx_pci_enable_aspm() when idle and
rtsx_pci_disable_aspm() when busy happens when dev_aspm_mode ==
DEV_ASPM_DYNAMIC.

This commit changes the enum so that 0 = DEV_ASPM_DYNAMIC matching the
old default behavior, fixing the pm regression with the other device-ids.

e455b69ddf misc: rtsx: Move Realtek Card Reader Driver to misc
Because Realtek card reader drivers are pcie and usb drivers,
and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.

 "There are no big surprising changes in this cycle, yet not too boring,
  either. The biggest change from diffstat POV is the removal of the

  As new features in ASoC side, there are two things: a new AC97 bus
  implementation and AMD Stony platform support. Both include the
  relevant changes shared with other subsystems, e.g. AC97 MFD changes
  and DRM AMD changes.

  Some other highlighted topics are:

   - A bunch of USB-audio drivers got the hardening against the
     malicious device accesses with a new helper code for endpoint
     sanity check

   - Lots of cleanups for ASoC Intel platform code, including support
     for their open source audio firmware

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

7b9651103b extcon: max77843: Add OTG power control to the MUIC driver
Enabling power on VBUS micro-usb pin is required only when passive OTG
cable is connected. Initially OTG VBUS power control was planned to be
done in charger driver. However such information is not really available
from the extcon notifications, so VBUS power control has to be done
directly in MUIC driver, which has all information about the attached
accessory.

For example SmartDock is externally powered accessory, provides OTG
(USB HOST) functionality and use VBUS pin for charging a device battery,
so the VBUS charging pump should be disabled in such case.

176aa36012 extcon: Split out extcon header file for consumer and provider device
The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect the
   state/properties of external connector. Also, it notifies the
   state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
   from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API for
both provider and consumer device driver. To clarify the meaning of
header file and to remove the wrong use-case on consumer device,
this patch separates into extcon.h and extcon-provider.h.

[Description for include/linux/{extcon.h|extcon-provider.h}]
- extcon.h includes the extcon API and data structure for extcon consumer
  device driver. This header file contains the following APIs:
  : Register/unregister the notifier to catch the change of extcon device
  : Get the extcon device instance
  : Get the extcon device name
  : Get the state of each external connector
  : Get the property value of each external connector
  : Get the property capability of each external connector

- extcon-provider.h includes the extcon API and data structure for extcon
  provider device driver. This header file contains the following APIs:
  : Include 'include/linux/extcon.h'
  : Allocate the memory for extcon device instance
  : Register/unregister extcon device
  : Set the state of each external connector
  : Set the property value of each external connector
  : Set the property capability of each external connector

511cb17448 mfd: tps65217: Introduce dependency on CONFIG_OF
Currently the driver boots only via device tree hence add a
dependency on CONFIG_OF. This leaves with a bunch of unused code
so clean that up. This patch also makes use of probe_new function
in place of the probe function so as to avoid passing i2c_device_id.

d81851c176 regulator: axp20x: Add support for AXP813 regulators
The AXP813 PMIC has 7 DC-DC buck regulators, 16 LDOs (including the
fixed RTC LDO and 2 GPIO LDOs), and 1 switchable. The drive-vbus
feature is also supported. All the hardware details are very similar
to the AXP803, with the following exceptions:

  - Extra DCDC7 buck regulator, with the same range as DCDC6

  - SWitch now has a separate supply pin, instead of being chained
    internaly from DCDC1

  - RTC LDO output voltage is now 1.8V

  - FLDO3 is an LDO with switchable supplies, but unconfigurable output
    voltage. The voltage is always half that of its supply.

Support for FLDO3 is currently unimplemented, as it requires runtime
switching of its supplies, something the regulator subsystem does not
support. It is not used in either the reference designs nor actually
produced boards available.

a5c6951c49 mfd: wm97xx-core: core support for wm97xx Codec
The WM9705, WM9712 and WM9713 are highly integrated codecs, with an
audio codec, DAC and ADC, GPIO unit and a touchscreen interface.

Historically the support was spread across drivers/input/touchscreen and
sound/soc/codecs. The sharing was done through ac97 bus sharing. This
model will not withstand the new AC97 bus model, where codecs are
discovered on runtime.
