2c52b1efd6 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.

5c03b53cb7 Pin control fixes for the v4.9 cycle: 
- Fix a host of runtime problems with the Intel
   Cherryview driver: suspend/resume needs to be
   marshalled properly, and strange effects from BIOS
   interaction during suspend/resume need to be
   dealt with.
 
 - A single bit was being set wrong in the Aspeed
   driver.
 
 - Fix an iProc probe ordering fallout resulting from
   v4.9 refactorings for bus population.
 
 - Do not specify a default trigger in the ST Micro
   cascaded GPIO IRQ controller: the kernel will moan.
 
 - Make IRQs optional altogether on the STM32 driver,
   it turns out not all systems have them or want them.
 
 - Fix a re-probe bug in the i.MX driver, it will
   eventually crash if probed repeatedly, not good.

31a3a7b5b2 PCI: rockchip: Add three new resets as required properties 
pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory.  But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst.  The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.

7970b9e6a5 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.

  - 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

* 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.

 could probably have been delayed to 4.10, but they're not scary and just
 plumbing up driver changes that went in during the merge window.

c7c88e998a 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)

   - Fix an endian type related sparse warnings.
 * ad7150
   - Constify the event attribute_group structures.
 * ad7152

   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.

   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

   attributes.

   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.

   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.

Jonathan writes:

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

8eb37aff76 pinctrl: aspeed-g5: Fix pin association of SPI1 function 
The SPI1 function was associated with the wrong pins: The functions that
those pins provide is either an SPI debug or passthrough function
coupled to SPI1. Make the SPI1 mux function configure the relevant pins
and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins
that were already defined.

The notation used in the datasheet's multi-function pin table for the SoC is
often creative: in this case the SYS* signals are enabled by a single bit,
which is nothing unusual on its own, but in this case the bit was also
participating in a multi-bit bitfield and therefore represented multiple
functions. This fact was overlooked in the original patch.

Merge tag 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull more rdma updates from Doug Ledford:
 "This merge window was the first where Huawei had to try and coordinate
  their patches between their net driver and their new roce driver
  (similar to mlx4 and mlx5).

  They didn't do horribly, but there were some issues (and we knew that
  because they simply didn't know what to do in the beginning). As a
  result, I had a set of patches that depended on some patches that
  normally would have come to you via Dave's tree. Those patches have
  been on netdev@ for a while, so I got Dave to give me his approval to
  send them to you. As such, the other 29 patches I had behind them are
  also now ready to go.

  This catches the hns and hns-roce drivers up to current, and for
  future patches we are working with them to get them up to speed on how
  to do joint driver development so that they don't have these sorts of
  cross tree dependency issues again. BTW, Dave gave me permission to
  add his Acked-by: to the patches against the net tree, but I've had
  this branch through 0day (but not linux-next since it was off by
  itself) and I didn't want to rebase the series just to add Dave's ack
  for the 8 patches in the net area.

  Updates to the hns drivers:

   - Small patch set for hns net driver that the roce patches depend on

   - Various fixes to the hns-roce driver

   - Add connection manager support to the hns-roce driver"

This includes the device tree binding and I2C core changes to support
 the i2c-bus subnode that I2C masters can use to describe their slaves
 in a separate namespace and therefore avoid clashing with potentially
 other subnodes.

56e520c7a0 IOMMU Updates for Linux v4.9 
Including:
 
 	* Support for interrupt virtualization in the AMD IOMMU driver.
 	  These patches were shared with the KVM tree and are already
 	  merged through that tree.
 
 	* Generic DT-binding support for the ARM-SMMU driver. With this
 	  the driver now makes use of the generic DMA-API code. This
 	  also required some changes outside of the IOMMU code, but
 	  these are acked by the respective maintainers.
 
 	* More cleanups and fixes all over the place.
