Second round of new device support, cleanups and fixes for IIO in the 4.10 cycle
This includes two branch merges for elements that may also go via MFD.
New device support
* cros_ec
- new driver to support these Chrome OS contiguous sensors which are behind
the Chrome OS embedded controller. Requires a few minor MFD and chrome
platform changes. One follow up fix deals with some dependency issues in
Kconfig.
* mpu-3050
- new driver and device tree bindings for this venerable device.
* st_accel
- support for the lng2dm an
Driver features
* ad7192
- Add DVdd regulator handling
* ad9832
- Add DVDD regulator handling
* at91
- Suspend and resume support
* si7020
- Device tree bindings
* ti-am335x
- DMA support - uses dma to accelerate short bursts of read back rather
than full blown DMA buffer support. Greatly improved performance.
Includes an MFD addition to give access to the address needed for DMA.
* tsl2583
- Device tree bindings
Cleanups and minor fixes
* ad7192
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
- Rename reg variable to reflect which regulator it is
* ad5933
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* ad7746
- Fix a missing return value (fallout from previous patch set)
* ad7780
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* ad9832
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
- Rename reg regulator to reflect which one it is
* ad9834
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* hts221
- Remove a duplicated include
* maxim thermocouple
- Handle a wrong storage side in read function. Prevent any problems that
might be introduced by additions to this driver in future.
* tsl2583 - big set from Brian Masney to drive this towards a staging
graduation.
- Convert to iio_chan_spec and read_raw / write_raw (in a couple of steps)
- Improved error handling in various functions
- Drop redundant power_state custom sysfs attribute.
- Use IIO_*_ATTR* macros for remaining attributes.
- Return an error code to userspace on invalid parameters being writen to
sysfs files.
- Add locking to various attribute accesses to remove possible races.
- Add defines for various magic numbers.
- Use smbus_read_byte_data instead of a write_byte followed by read_byte.
- Query only relevant registers in probe.
- Tidy up ordering of code comments.
- Remove a pointless power off sequence in taos_chip_on.
- Don't bother shutting down the chip when updating the lux table.
The table is held entirely in the driver and doesn't effect the chip at all.
- Drop a redundant i2c call in taos_als_calibrate where the same register
is read twice in a row.

iio: cros_ec_sensors_core: Add common functions for the ChromeOS EC Sensor Hub.
Add the core functions to be able to support the sensors attached behind the ChromeOS Embedded Controller and used by other IIO cros-ec sensor drivers. The cros_ec_sensor_core driver matches with current driver in ChromeOS 4.4 tree, so it includes all the fixes at the moment. The support for this driver was made by Gwendal Grignou. The original patch and all the fixes has been squashed and rebased on top of mainline.

First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well
have already been picked up by Greg but git will sort that out for us.
Also some good staging cleanup work from other sources. Thanks Brian and Lars
in particular for this.
New device support
* ACCES 104-quad-8
- New driver for this 8 channel encoder input board. Lots of new ABI with
this one.
* AD7766
- New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and
AD7767-2 24 bit ADCs.
* dmard 10
- New driver for this 3 axis accelerometer.
* Honeywell ABP pressure sensors.
- New driver covering 56 parts in this series (too many to list here!)
* HTS221
- New driver to support this relative humidiy and temperature device.
* LMP91000
- New driver for this potentiostat (form of chemical sensor). Nice example
of use of the buffered consumer interfaces and the use of a consumer
provided trigger.
* MiraMEMS DA311
- New driver for this 3 axis accelerometer.
* MiraMEMS DA280
- New driver for this 3 axis accelerometer. Follow up caught up with
vendor prefixes for these.
Staging graduations
* isl29018 light sensor
- Fixes and cleanups listed below (thanks for your hard work on this Brian!)
* sca3000
- Fixes and cleanups listed below. This was one of the small set of drivers
that went into staging when IIO was first added. Turns out it had a few
bugs and needed to be brought into the modern era! Not clear if I am
the only person who actually has one of these still wired to a board.
New features (Core)
- Add an iio_trigger_validate_own_device helper which relies on the device
and trigger having the same parent. Convenient to have this for some
of the more complex trigger / device interactions. Was hand rolled in
a few drivers already so good to bring it into the core.
- Add an iio_read_channel_offset in kernel access helper (similar to
the existing one for scale).
- IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These
lead some rather contrived function naming, but there is no denying they
do reduced boilerplate. I'm going to resist their introduction in
drivers 'unless' they form part of a larger set of cleanups.
- Counter channel type and index type.
New features (Drivers)
* hdc100x
- Triggered buffer support.
* mcp4725
- Device tree bindings and support.
- Voltage reference selection.
* ti-adc0832
- Triggered buffer support.
* ti-adc161s626
- Add regulator support allowing _scale and _offset values to be established
and exported.
New features (Tools)
* iio_generic_buffer
- -A option to force enable all channels rather than faulting if some are
already enabled (like -a does). Followup patches tidied this support up.
Cleanups (Core)
- Use kmalloc_array in iio_scan_mask_set.
- Take event_attrs field of iio_info structure constant
- Staging todo list updates. Most of it was long done.
- MAINTAINERS had a wrong directory listing.
Cleanups (Drivers)
* Missing i2c trivial devices entries.
* ad5592r
- Fix an endian type related sparse warnings.
* ad7150
- Constify the event attribute_group structures.
* ad7152
- Add some blank lines to improve readability.
- Sampling frequency control via chan-info element rather than hand rolled
attributes.
- add a new lock to avoid use of mlock for non state change related locking.
* ad7280
- Constify atrribute_group structure (second patch covers the event ones)
* ad7606 (Lars is driving most of the cleanup on this with some additions from
Eva)
- Fix improper setting of oversampling pins. This has been broken a very
long time in this staging driver, so not going to push this back to stable.
- Implement oversampling configuration via the chan_info mask element.
- Remove an unused int_vref_mv field.
- Remove a reundant name field from ad7606_chip_info.
- Remove default device configuration from platform_data in favour of
whatever the power on defaults are.
- Remove out of band error reporting in the kernel log as not providing
much information.
- Fix oversampling ratio by having 1 be the value for no oversampling.
- Avoid allocating buffer for each data capture.
- Factor out common code between periodic and one-shot capture.
- Move set_drvdat into common code.
- Let the common probe function return int rather than jumping through
an ERR_PTR.
- Pass struct device * into common remove to simplify code.
- Always run trigger handler only once per event (no one can remember why
it was being possibly done twice).
- Move over to the GPIO descriptor API to shorten and clarify code.
- Move the buffer code into the main file as it's not optional and is
now rather short in this driver.
- Fix the naming of the supply regulator.
- Rework regulator handling to handle errors including deferred probing.
- Tidy up a ptr_err or 0 return.
* ad7746
- Sampling frequency control via info_mask element rather than hand rolled
* ad7758
- Sampling frequency control via info_mask element rather than hand rolled
attributes.
* ad7816
- Constify the event attribute_group structure.
* adt7316
- Constify the event attribute group structures.
* ak8974
- Cleanup some sparse warnings about endian types.
* ak8975
- Cleanup some sparse warnings about endian types.
* bmi160
- Spare endian warning cleanups.
* isl29018 (towards staging graduation)
- Remove unusedvariables and defines.
- Improve consistency of error handling.
- Signed / unsigned comparison fixes.
- Use the IIO_DEVICE_ATTR_{RO, RW} macros
- Fix a race in in_illuminance_scale_available_show.
- Cleanup exit points of _read_raw
- Sanity check if in suspended state during a write_raw call as was already
done for read_raw.
- Document device tree bidnings.
- Document infrared supression controls.
- Add some newlines to improve readability and drop one that shouldn't be
there.
- Fix a poorly named functions name.
- Fix multiline coment syntax.
- Tidy up a pair or return statements by unifying them.
- Rename description in Kconfig for consistency with similar drivers.
* lidar
- cleanup power management by dropping unnecessary call.
* ltr501
- Use the claim_direct_mode helpers. Fix a race condition along the way.
* max1027
- Fix a dubious x | !y sparse warning.
- Use the new iio_trigger_validate_own_device helper.
* max440000
- Clean up some sparse warnings about endian types.
* mcp4725
- Use the regulator framework to establish the reference voltage rather than
getting it from platform data.
- Tidy up a comment typo.
- Fix a wrong PTR_ERR query (wrong regulator).
* mma7660
- Take a mma7660_nscale static.
* mma8452
- Use the new iio_trigger_validate_own_device helper.
- Use claim_direct_mode helpers - fix a race condition along the way.
* mpl3115
- Use claim_direct_mode helpers - fix a race condition along the way.
* ms65611
- Tidy up regulator error handling and clean out a static warning in the mix.
* sca3000
- Avoid a potential unitialized variable if a hardware read returns a value
that isn't actually supported (mostly warning supression).
- Fix a use before setting of the indio_dev->buffer pointer. Broken for
a very long time so not going to rush this into stable.
- Merge buffer file with core file. We used to always split these.
Sometimes it's just not worth the hassle. In this case the device's main
feature is it's hardware fifos so unlikely anyone would want to run it
without.
- Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
once we have only one file.
- Fix cleaning of flag + setting of size of scan. Without this you can't
start the buffer twice and expect sensible (or any) results. Again,
broken for a long time so not heading for stable.
- Drop the custom watershed setting ABI - for now we'll just support one
value.
- Move to a hybrid hard / soft buffer design (how we've been doing it
for similar devices for a while now!)
- Cleanup some unusued variables.
- Use a fake channel to support core handling of freefall event registration.
- Cleanup the register defines.
- Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
Been broken since first admission of IIO to the staging tree.
- Add readback of the 3db low pass filter frequency and later writing
allowing droppign of custom measurement mode attributes as they can
be represented by the filter choices that is their main characteristic.
- Drop non standard revision attr and replace with dev_info on probe.
- Avoid a race in probe.
- Various formatting fixes.
- Kernel-docify docs that were very nearly in the write format.
* tsl2583
- Constify attribute_group structure.
* zpa2326
- Drop a redundant DEBUG ifdef.
Cleanups (Tools)
* iio_generic_buffer
- Fix the ? arguement. Previously it sort of worked as you got the help
message as a result of it not recognising the arguement.

cxl: Prevent adapter reset if an active context exists
This patch prevents resetting the cxl adapter via sysfs in presence of
one or more active cxl_context on it. This protects against an
unrecoverable error caused by PSL owning a dirty cache line even after
reset and host tries to touch the same cache line. In case a force reset
of the card is required irrespective of any active contexts, the int
value -1 can be stored in the 'reset' sysfs attribute of the card.
The patch introduces a new atomic_t member named contexts_num inside
struct cxl that holds the number of active context attached to the card
, which is checked against '0' before proceeding with the reset. To
prevent against a race condition where a context is activated just after
reset check is performed, the contexts_num is atomically set to '-1'
after reset-check to indicate that no more contexts can be activated on
the card anymore.
Before activating a context we atomically test if contexts_num is
non-negative and if so, increment its value by one. In case the value of
contexts_num is negative then it indicates that the card is about to be
reset and context activation is error-ed out at that point.

iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8
The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

usb: core: Introduce a USB port LED trigger
This commit adds a new trigger responsible for turning on LED when USB device gets connected to the selected USB port. This can can useful for various home routers that have USB port(s) and a proper LED telling user a device is connected. The trigger gets its documentation file but basically it just requires enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1). There was a long discussion on design of this driver. Its current state is a result of picking them most adjustable solution as others couldn't handle all cases. 1) It wasn't possible for the driver to register separated trigger for each USB port. Some physical USB ports are handled by more than one controller and so by more than one USB port. E.g. USB 2.0 physical port may be handled by OHCI's port and EHCI's port. It's also not possible to assign more than 1 trigger to a single LED and implementing such feature would be tricky due to syncing triggers and sysfs conflicts with old triggers. 2) Another idea was to register trigger per USB hub. This wouldn't allow handling devices with multiple USB LEDs and controllers (hubs) controlling more than 1 physical port. It's common for hubs to have few ports and each may have its own LED. This final trigger is highly flexible. It allows selecting any USB ports for any LED. It was also modified (comparing to the initial version) to allow choosing ports rather than having user /guess/ proper names. It was successfully tested on SmartRG SR400ac which has 3 USB LEDs, 2 physical ports and 3 controllers. It was noted USB subsystem already has usb-gadget and usb-host triggers but they are pretty trivial ones. They indicate activity only and can't have ports specified. In future it may be good idea to consider adding activity support to usbport as well. This should allow switching to this more generic driver and maybe marking old ones as obsolete. This can be implemented with another sysfs file for setting mode. The default mode wouldn't change so there won't be ABI breakage and so such feature can be safely implemented later. There was also an idea of supporting other devices (PCI, SDIO, etc.) but as this driver already contains some USB specific code (and will get more) these should be probably separated drivers (triggers).

genirq: Expose interrupt information through sysfs
Information about interrupts is exposed via /proc/interrupts, but the format of that file has changed over kernel versions and differs across architectures. It also has varying column numbers depending on hardware. That all makes it hard for tools to parse. To solve this, expose the information through sysfs so each irq attribute is in a separate file in a consistent, machine parsable way. This feature is only available when both CONFIG_SPARSE_IRQ and CONFIG_SYSFS are enabled. Examples: /sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7 /sys/kernel/irq/18/chip_name: IR-IO-APIC /sys/kernel/irq/18/hwirq: 18 /sys/kernel/irq/18/name: fasteoi /sys/kernel/irq/18/per_cpu_count: 0,0 /sys/kernel/irq/18/type: level /sys/kernel/irq/25/actions: ahci0 /sys/kernel/irq/25/chip_name: IR-PCI-MSI /sys/kernel/irq/25/hwirq: 512000 /sys/kernel/irq/25/name: edge /sys/kernel/irq/25/per_cpu_count: 29036,0 /sys/kernel/irq/25/type: edge [ tglx: Moved kobject_del() under sparse_irq_lock, massaged code comments and changelog ] Signed-off-by: Craig Gallek <kraig@google.com> Cc: David Decotigny <decot@google.com> Link: http://lkml.kernel.org/r/1473783291-122873-1-git-send-email-kraigatgoog@gmail.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de> |

The unmapping cleanup would then be handled by the generic hotunplug code paths in multipahd like is done for iSCSI, FC/FCOE, SAS, etc. Signed-off-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |

arm64: cpuinfo: Expose MIDR_EL1 and REVIDR_EL1 to sysfs
It can be useful for JIT software to be aware of MIDR_EL1 and REVIDR_EL1 to ascertain the presence of any core errata that could affect code generation. This patch exposes these registers through sysfs: /sys/devices/system/cpu/cpu$ID/regs/identification/midr_el1 /sys/devices/system/cpu/cpu$ID/regs/identification/revidr_el1 where $ID is the cpu number. For big.LITTLE systems, one can have a mixture of cores (e.g. Cortex A53 and Cortex A57), thus all CPUs need to be enumerated. If the kernel does not have valid information to populate these entries with, an empty string is returned to userspace.

ACPI: add support for loading SSDTs via configfs
New tables can be loaded by creating directories under /config/table/ and writing the AML code into the aml table attribute. Various table attributes will be readable once the table is successfully loaded. Unloading tables is not supported at the moment, but it can be easily implemented once ACPI loading functions provide a table handle to be used for unloading.

iio:core: timestamping clock selection support
Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.

USB fixes for 4.7-rc4
Here are a bunch (65) of USB fixes for 4.7-rc4. Sorry about the quantity, I've been slow in getting these out. The majority are the "normal" gadget, musb, and xhci fixes, that we all are used to. There are also a few other tiny fixes resolving a number of reported issues that showed up in 4.7-rc1. All of these have been in linux-next.

First round of IIO new device support, features and cleanups for the 4.8 cycle.
New device support
* ads1015
- add ads1115 support
* bma220 accelerometer
- new driver
- triggered buffer support.
* bmc150
- add bmm150 support.
* bmp280
- bme280 support with addition of humidity channel.
* max5487 potentiometer
- new driver
* MMA7660FC accelerometer.
- New driver
* st-pressure
- support for the lps22hb
* loop trigger.
- This one is *nasty* but we have real applications (parrot drones) where
it is useful. The trigger basically spins as hard as it can firing off
a new trigger each time all triggered devices come back to say they are
done. It doesn't hang a machine even when doing it on a dummy driver.
A lot nicer than having this implemented within lots of device drivers
anyway.
Core stuff
* Add support to create IIO devices via configfs (similar to we did for
triggers a while back) + docs.
* New channel types
- IIO_ELECTRICAL_CONDUCTIVITY
* Couple of MAINTAINERS patches to list the device tree bindings.
* Make trigger ops structure non optional (comment fix). It hasn't been for
an awful long time, but that's not what the description said.
New features
* ak8975
- support adapters that are limited to byte data only by allowing the
emulated block read i2c function that was recently introduced.
* atlas-ph
- support atlas-ec (electrical conductivity sensor)
* bmi160
- add available frequency and scale attributes to make the driver
more user friendly (and avoid having to read the datasheet to know
what will work).
* dummy
- move creation to configfs interface. It's not real hardware so we
are not that worried about the ABI breakage ;)
* mma8452
- oversampling ration support
* nau7802
- expose available gains to make life easier for userspace.
* st-sensors
- allow use of emulation for SMBus block reads as all the st parts support
it.
* ti-ads1015
- list datasheet names to allow their use by inkernel consumers.
* Various module alias additions to help auto probing. Drop one redundant one
as well.
Cleanups
* ad7266, ad7476, ad7887, ad7923, ad799x
- use direct mode claim function rather than open coding it during sensor
read (prevents switching on buffers mid read).
* ad7793, ad7791
- use direct mode claim to prevent frequency changes when buffers running.
* afe440x - These are ABI breaking but the driver requires custom userspace
code to do anything useful anyway and that is still being written and under
control of TI. Ultimately we may have other libraries to do pulse
oximetry with these devices but we aren't aware of any yet.
- kernel-doc format fixes
- drop ifdef fun around of_match_ptr - it's not worth the mess to save
a tiny amount of space.
- drop some unnecessary register initializations.
- drop the weird locked gain modes as they gain us nothing (can just set
all gains separately).
- remove handling of offset attributes seeing as no channels actually have
them (oops)
- Drop the LED3 input channel as it's an alias for ALED2.
- *big one* remove channel names - an experiment that turned out to not
make sense - see patch for details.
- use regmap fields to clean up code.
- tie the tia gain stages to appropriate channels in the ABI as that is
what they really effect. Same with the LED currents.
- cleanout some unused defines and fix a missnamed one.
* atlas-ph
- reorganise to allow support of other similar parts.
* bmc150
- document supported chips in kconfig help.
* jsa1212
- drop an unneeded i2c functionality check for functionality the driver
doesn't use.
* mxs-lradc
- simply touch screen registration code.
- remove the touch screen unregister as all devm based now.
- disable only those channels that are masked in hardware stop (others
are already dealt with elsewhere)
* st-sensors
- unexport st_sensors_get_buffer_element as nothing outside the st-sensors
core driver uses it.
- fix handling of failure to start up regulators.
* tpl0102
- drop an i2c functionality test for features that aren't needed.
* ti-am335x
- use variable name rather than type in sizeof for clarity.
- use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.
Tools
* Add install / uninstall to makefile. Someone cares, so presumably
some people will find it useful!
* generic_buffer
- rename to iio_generic_buffer to line up with other tools.
- handle cleanup when receiving signals
- Add a --device-num option and a --trigger-num option rather than
relying on naming which doesn't work if you have two of the same part.

First round of iio fixes for the 4.7 cycle.
A slightly bumper set due to travel delaying the pull request and a fair few
issues with the recent merge window patches. Patches all over the place.
The st-sensors one is probably the most involved, but definitly solves the
issues seen. Note there are some other issues around that handler
(and the fact that a lot of boards tie a level interrupt chip to an
edge interrupt only irq chip). These are not regressions however, so
will turn up the slow route.
* core
- iio_trigger_attach_pollfunc had some really badly wrong error handling.
Another nasty triggered whilst chasing down issues with the st sensors
rework below.
* ad5592r
- fix an off by one error when allocating channels.
* am2315
- a stray mutex unlock before we ever take the lock.
* apds9960
- missing a parent in the driver model (which should be the i2c device).
Result is it doesn't turn up under /sys/bus/i2c/devices which some
userspace code uses for repeatable device identification.
* as3935
- ABI usage bug which meant a processed value was reported as raw. Now
reporting scale as well to ensure userspace has the info it needs.
- Don't return processed value via the buffer - it doesn't conform to
the ABI and will overflow in some cases.
- Fix a wrongly sized buffer which would overflow trashing part of the
stack. Also move it onto the heap as part of the fix.
* bh1780
- a missing return after write in debugfs lead to an incorrect read and
a null pointer dereference.
- dereferencing the wrong pointer in suspend and resume leading to
unpredictable results.
- assign a static name to avoid accidentally ending up with no name if
loaded via device tree.
* bmi160
- output data rate for the accelerometer was incorrectly reported. Fix it.
- writing the output data rate was also wrong due to reverse parameters.
* bmp280
- error message for wrong chip ID gave the wrong expected value.
* hdc100x
- mask for writing the integration time was wrong allowin g us to get
'stuck' in a particular value with no way back.
- temperature reported in celsius rather than millicelsius as per the
ABI.
- Get rid of some incorrect data shifting which lead to readings being
rather incorrect.
* max44000
- drop scale attribute for proximity as it is an unscaled value (depends
on what is in range rather than anything knowable at the detector).
* st-pressure
- ABI compliance fixes - units were wrong.
* st-sensors
- We introduced some nasty issues with the recent switch over to a
a somewhat threaded handler in that we broke using a software trigger
with these devices. Now do it properly. It's a larger patch than ideal
for a fix, but the logic is straight forward.
- Make sure the trigger is initialized before requesting the interrupt.
This matters now the interrupt can be shared. Before it was ugly and wrong
but short of flakey hardware could not be triggered.
- Hammer down the dataready pin at boot - otherwise with really
unlucky timing things could get interestingly wedged requiring a hard power
down of the chip.
