Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex use we have had with an analog front end made from discrete components. Brian Masney's work on moving the tsl2583 driver out of staging also feature extensively! New Drivers * DAC based on a digital potentiometer - New driver for the use of a dpot as a DAC. Includes bindings and Axentia entry in vendor prefixes. * Envelope detector baed on DAC and a comparator including device tree bindings. Staging Graduation * tsl2583. Core new features - Core provision for _available attributes. This one had been stalled for a long time until Peter picked it up and ran with it! - In kernel interface helpers to retrieve available info from channels. Driver new features * mcp4531 - Add range of available raw values (used for the dpot dac driver). Driver cleanups and fixes for issues introduced * ad7766 - Testing the wrong variable following devm_regulator_bulk_get introduced with the driver earlier in this cycle. * ad9832 - Fix a wrong ordering in the probe introduced in the previous set of patches. A use before allocation bug. * cros_ec_sensors - Testing for an error in a u8 will never work. * mpu3050 - Remove duplicate initializer for the module owner. - Add missing i2c dependency. - Inform the i2c mux core how it is used - step one in implifying device tree bindings. * st-sensors - Get rid of large number of uninformative defines in favour of putting the constants where they are relevant. It is clear what they are from where they are used. * tsl2583 - Fix unused function warning when CONFIG_PM disabled and remove the ifdefs in favour of __maybe_unused. - Refactor taos_chip_on to only read relevant registers. - Make sure calibscale and integration time are being set. - Verify chip is in ready to be used before calibration. - Remove some repeated checks for chip status (it's protected by a mutex so can't change until it's released) - Change current state storage from a tristate enum to a boolean seeing as only two values are actually used now. - Drop a redundant write to the control regiser in taos_probe (it's a noop) - Drop the FSF mailing address. - Clean up logging to not use hard coded function names (use __func__ instead). - Cleanup up variable and function name prefixes. - Alignment of #define fixes. - Fix comparison between signed and unsigned integer warnings. - Add some newlines in favour of readability. - Combine the two sysfs ABI docs that somehow ended up in different places. - Fix multiline comment syntax. - Move a code block to inside an else statement as it makes more sense there. - Change tsl2583_als_calibrate to return 0 rather than a value nothing reads. - Drop some pointless brackets - Don't assume 32bit unsigned int. - Change to a per device instance lux table. - Add missing tsl2583 to the list of supported devices in the intro comments. - Improve commment on clearing of interrupts. - Drop some uninformative comments. - Drop a memset call that doesn't do anything useful any more. - Don't initialize some return variables that are always set. - Add Brian Masney as a module author after all these changes. -----BEGIN PGP SIGNATURE----- iQIuBAABCAAYBQJYKMYhERxqaWMyM0BrZXJuZWwub3JnAAoJEFSFNJnE9BaIiNMP /00ZTTfPR/I5VtriTchGTgXN6lDTnypFk9Z4niynK3EIdF6Mw5XphQjtUzg7sJl4 U7yH89lzt0PxAJHylW5x0YOwrr6fyau+rNA2Kj26psaQpf5Yva0UDRexsomTZaad P005cf0yc4fuG/7KvjeONeLeaRXf9Qfs20r8htECLFhIGSE0qsGtfzUMn6tdbyn/ r/hxHR7oE2YThuFytX2sNJEJVmCDz+tTOz7kJv5L0e6Cg6cvMFizYUsoFYcZYGOQ DNicdRfW5FOidBMCqXzYLDBn+oY+a35g90hFV3CvYsfEm+X6BzTgr3FI3PHmtXHT RRAmRdgxg2z/rqp475f5EamRtZxEg0uktbqcs9bH8Bx7IDe8KtoNKLdPdxIT3T1D ZYb0RkpPmfnBq3bDGh7DJVWl+Ht9Fj0jaKRNyWgiyopA9c6zN4MKRA+HNSxKRvD7 Qizw0QIPbtEGkw6WbQrrOSSwzNY/dq51vrT0eBmMaGpjmdDpRKrK53/k7uwk3/Wv hjGWD5kdLRCAHL+EQKFssN/RgLS5PRhXsJQFeIYbH8VJFlEZ28j09gXJnjcpDucK CXv37q8CX6wJ2NB+i+skOvKpxArgv+Mr4oE9LNYZie65EUyN28/Ii1n9vYmTPTlG KXGKPynaR0sfrl+ir6+FCtuFXJnYC5WUqJH/yMRjA2z8 =mPkb -----END PGP SIGNATURE----- Merge tag 'iio-for-4.10c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third set of IIO new device support, features and cleanup for the 4.10 cycle.

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.

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.

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.

iio: Implement counter channel type and info constants
Quadrature encoders, such as rotary encoders and linear encoders, are devices which are capable of encoding the relative position and direction of motion of a shaft. This patch introduces several IIO constants for supporting quadrature encoder counter devices.

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> |

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.
