6a8b25abf1 1st round of IIO new device support, features and cleanup for the 4.18 cycle 
A nice mix this time of excellent cleanups (many to send drivers
 speeding toward staging graduations) and new drivers / device support.
 A good part of this is Brian Masney's never ending task on the tsl2x7x
 driver.  The end is in sight so hopefully we'll get that one out of
 staging very soon!
 
 New device support

   - Support AD5685R (was wrongly present as AD5685)
   - Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
     SPI DACs with various precisions.
   - Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
     I2C DACs with various percisions and numbers of channels.
 * Analog front end rescale driver - New driver.
   - Support current sensing usings a shunt resistor.
   - Support simple voltage dividers.
   - support simple current sense amplifiers.
 * TI dac5571
   - New driver and device bindings supporting:
     dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
     dac5573, dac6573 and dac7573
 * Meson-adc
   - Support for Meson AXG with DT bindings.
 * mpu6050
   - Support the mpu9255 which only requires additional WHOAMI entry and
     compatible string.
 * st_lsm6dsx
   - Support for lsm330dlc combinded accelerometer and gyro sensors with
     DT bindings.
 * stm32_adc
   - Add support for STM32MP1 with bindings.
 
 Staging graduations
 * adis16201 after some excelent cleanup by Himanshu Jha.
 * adis16029 after some excelent cleanup by Shreeya Patel.
 
 New features:
 * ABI docs
   - Add core ABI docs for angle channels.
 * inv_mpu6050
   - Provide support for the full range of interrupts the device
     supports.
 * st_accel
   - Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
 * stx104
   - Provide a multiple gpio get function.
 
 Cleanups / Minor fixes
 * core
   - Use new nested structure support to improve kernel-doc.
 * ad2s1200
   - Use be16_to_cpup instead of opencoding.
 * ad5686
   - Indentation tidy up.
   - Switch to SPDX
   - Refactor to allow various numbers of channels.
   - Refactor to separate core and SPI specific support, prior to
     addition of i2c equivalent devices.
 * ad7606
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * ad7746
   - Replace opencoded byte swapped i2c calls with _swapped variants.
   - White space and line break readability improvements.
   - Reorder includes and variable declarations where appropriate.
 * ad7791
   - Changes to the AD ADC library used by this driver took in the
     sampling frequency.  This lead to be the wrong path being the one
     tied to the resulting attribute, so it didn't work, and a warning
     to be printed.
 * ad7780
   - Remove apparent support for sampling frequency control on devices
     that don't support changing the sampling attributes.
 * ade7854
   - Fix a read of the wrong number of bits.
   - Improve error handling on i2c read/write errors.
   - Rework i2c and spi code to reduce duplication.
 * adis16201 (staging)
   - Improve meaning inherent in some macro names by adding units etc
     where relevant.
   - Adjust comments to improve detail and drop the irrelevant.
   - Rename register address definitions definitions to add a _REG
     postfix, clearly separating them from field definitions. Reorganize
     the definitions to group register address and fields.
   - Use sign_extend32 rather than open coding.
   - Reverse Xmas tree ordering where appropriate and align function args.
   - Remove unused headers.
   - Use GENMASK where appropriate instead of open coding.
 * adis16209 (staging)
   - Indent field definitions to visually separate them from
     register address definitions.
   - Use reverse xmas tree ordering where appropriate.
   - Add some whitespace where it will help readability.
   - Drop some unused headers.
   - Use GENMASK where appropriate.
 * ad2s1200
   - Drop unnecessary includes and reorder alphabetically.
   - Reverse xmas tree and blank line cleanups.
 * atlas-ph-sensor
   - Use msleep instead of usleep_range where the precise value doesn't
     matter and the delays are long.
 * bcm150
   - Drop transaction splitting as core now handles it.
 * cros_ec
   - Move the shared header to the include/iio/common directory.
     This brings it inline with the other multiple type devices.
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * hid-sensors
   - Use drvdata directly from device rather than boucing via the
     platform_device structure.
 * inv_mpu6050
   - Clear out a second function definition for the same function.
   - Don't flush fifo when the iio buffer is full but just drop excess
     data.

   - Refactor to pull raw data read out of read_raw function.
   - Simplify data reading error paths.
   - Only enable the i2c mux for chips with the i2c aux bus (not icm20608)

 * mcp4018
   - Switch to using i2c .probe_new.
 * mcp4351
   - switch to using i2c .probe_new.

     directions on the threshold events into a single value as the
     hardware doesn't separate them.
   - Move integration_time* attributes from light channel to
     intensity value as they effect the intensity readings directly
     and the light reading only indirectly.  Hence this better
     reflects reality. Also move the calibscale_available.
   - Avoid returning an error in the IRQ handler.
   - Hard code the reg value in _clear_interrupts as it only takes
     one value in the code.   Result is the function has little
     purpose so opencode the two remaining i2c_smbus_write_byte
     calls.
   - Drop some unnecessary checking of the chip status register.
   - Tidy up return path in _write_interrupt_config.
   - Tidy up the ID verification code.

The AFFS filesystem is still in use by m68k community (Link #2), but as
there was no code activity and no maintainer, the filesystem appeared on
the list of candidates for staging/removal (Link #1).

I volunteer to act as a maintainer of AFFS to collect any fixes that
might show up and to guard fs/affs/ against another spring cleaning.

8b74816b5a iio: afe: rescale: new driver 
If an ADC channel measures the midpoint of a voltage divider, the
interesting voltage is often the voltage over the full resistance.
E.g. if the full voltage is too big for the ADC to handle.
Likewise, if an ADC channel measures the voltage across a shunt
resistor, with or without amplification, the interesting value is
often the current through the resistor.

This driver solves these problems by allowing to linearly scale a channel
and/or by allowing changes to the type of the channel.

Here are some small char and misc driver fixes for 4.17-rc3
 
 A variety of small things that have fallen out after 4.17-rc1 was out.
 Some vboxguest fixes for systems with lots of memory, amba bus fixes,
 some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other
 minor things that resolve problems that people reported.
 
 The amba bus fixes took twice to get right, the first time I messed up
 applying the patches in the wrong order, hence the revert and later
 addition again with the correct fix, sorry about that.
 
 All of these have been in linux-next with no reported issues.

  Some vboxguest fixes for systems with lots of memory, amba bus fixes,
  some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other
  minor things that resolve problems that people reported.

  The amba bus fixes took twice to get right, the first time I messed up
  applying the patches in the wrong order, hence the revert and later
  addition again with the correct fix, sorry about that.

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

Here are 2 staging driver fixups for 4.17-rc3.
 
 The first is the remaining stragglers of the irda code removal that you
 pointed out during the merge window.  The second is a fix for the
 wilc1000 driver due to a patch that got merged in 4.17-rc1.
 
 Both of these have been in linux-next for a while with no reported

ee7141c929 ARM: SoC fixes for 4.17 
This round of fixes has two larger changes that came in last week:
 
 - A set of a couple of patches all intended to finally turn on
   USB support on various Amlogic SoC based boards. The respective
   driver were not finalized until very late before the merge window
   and the DT portion is the last bit now.
 - A defconfig update for gemini that had repeatedly missed the
   cut but that is required to actually boot any real machines
   with the default build.
 
 The rest are the usual small changes:
 
 - A fix for a nasty build regression on the OMAP memory drivers
 - A fix for a boot problem on Intel/Altera SocFPGA
 - A MAINTAINER file update
 - A couple of fixes for issues found by automated testing
   (kernelci, coverity, sparse, ...)
 - A few incorrect DT entries are updated to match the hardware

Pull libnvdimm fixes from Dan Williams:
 "A regression fix, new unit test infrastructure and a build fix:

   - Regression fix addressing support for the new NVDIMM label storage
     area access commands (_LSI, _LSR, and _LSW).

     The Intel specific version of these commands communicated the
     "Device Locked" status on the label-storage-information command.

     However, these new commands (standardized in ACPI 6.2) communicate
     the "Device Locked" status on the label-storage-read command, and
     the driver was missing the indication.

     Reading from locked persistent memory is similar to reading
     unmapped PCI memory space, returns all 1's.

   - Unit test infrastructure is added to regression test the "Device
     Locked" detection failure.

   - A build fix is included to allow the "of_pmem" driver to be built
     as a module and translate an Open Firmware described device to its
     local numa node"

4177381b44 iio:dac:ad5686: Add AD5671R/75R/94/94R/95R/96/96R support 
The AD5694/AD5694R/AD5695R/AD5696/AD5696R are a family of 4 channel DACs
with 12-bit, 14-bit and 16-bit precision respectively. The devices have
either no built-in reference, or built-in 2.5V reference.

The AD5671R/AD5675R are similar, except that they have 8 instead of 4
channels.

These devices are similar to AD5672R/AD5676/AD5676R and
AD5684/AD5684R/AD5684/AD5685R/AD5686/AD5686R, except that they use i2c
instead of spi.

0357e488b8 iio:dac:ad5686: Refactor the driver 
In this patch restructures the existing ad5686 driver by adding a module
for SPI and a header file, while the baseline module deals with the
chip-logic.

This is a necessary step, as this driver should support in the future
similar devices which differ only in the type of interface used (I2C
instead of SPI).

ca4e7c5120 The large diff this time around is from the addition of a new clk driver 
for the TI Davinci family of SoCs. So far those clks have been supported
 with a custom implementation of the clk API in the arch port instead of in
 the CCF. With this driver merged we're one step closer to having a single
 clk API implementation.
 
 The other large diff is from the Amlogic clk driver that underwent some
 major surgery to use regmap. Beyond that, the biggest hitter is Samsung
 which needed some reworks to properly handle clk provider power domains
 and a bunch of PLL rate updates.
 
 The core framework was fairly quiet this round, just getting some cleanups
 and small fixes for some of the more esoteric features. And the usual
 set of driver non-critical fixes, cleanups, and minor additions are here as
 well.
 
 Core:
  - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
  - debugfs ops macroized to shave some lines of boilerplate code
  - Always calculate the phase instead of caching it in clk_get_phase()
  - More __must_check on bulk clk APIs
 
 New Drivers:
  - TI's Davinci family of SoCs
  - Intel's Stratix10 SoC
  - stm32mp157 SoC
  - Allwinner H6 CCU
  - Silicon Labs SI544 clock generator chip
  - Renesas R-Car M3-N and V3H SoCs
  - i.MX6SLL SoCs
 
 Removed Drivers:
  - ST-Ericsson AB8540/9540
 
 Updates:
  - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
  - STM32F469 DSI and STM32F769 sdmmc2 support
  - GPIO clks can sleep now
  - Spreadtrum SC9860 RTC clks
  - Nvidia Tegra MBIST workarounds and various minor fixes
  - Rockchip phase handling fixes and a memory leak plugged
  - Renesas drivers switch to readl/writel from clk_readl/clk_writel
  - Renesas gained CPU (Z/Z2) and watchdog support
  - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
  - Qualcomm PM8921 PMIC XO buffers
  - Amlogic migrates to regmap APIs
  - TI Keystone clk latching support
  - Allwinner H3 and H5 video clk fixes
  - Broadcom BCM2835 PLLs needed another bit to enable
  - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix

The number of I2C host controller drivers keeps increasing, and although
I had some success acquiring specific driver maintainers, my bandwidth
is by far not enough to act as a fallback for the rest of the drivers.
To reflect this status-quo in MAINTAINERS, add a separate entry for I2C

Merge tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "This cycle was was not something I ever want to repeat as there were
  several late changes that have only now just settled.

  Half of the branch up to commit d2c997c0f1 ("fs, dax: use
  page->mapping to warn...") have been in -next for several releases.
  The of_pmem driver and the address range scrub rework were late
  arrivals, and the dax work was scaled back at the last moment.

  The of_pmem driver missed a previous merge window due to an oversight.
  A sense of obligation to rectify that miss is why it is included for
  4.17. It has acks from PowerPC folks. Stephen reported a build failure
  that only occurs when merging it with your latest tree, for now I have
  fixed that up by disabling modular builds of of_pmem. A test merge
  with your tree has received a build success report from the 0day robot
  over 156 configs.

  An initial version of the ARS rework was submitted before the merge
  window. It is self contained to libnvdimm, a net code reduction, and
  passing all unit tests.

  The filesystem-dax changes are based on the wait_var_event()
  functionality from tip/sched/core. However, late review feedback
  showed that those changes regressed truncate performance to a large
  degree. The branch was rewound to drop the truncate behavior change
  and now only includes preparation patches and cleanups (with full acks
  and reviews). The finalization of this dax-dma-vs-trnucate work will
  need to wait for 4.18.

  Summary:

   - A rework of the filesytem-dax implementation provides for detection
     of unmap operations (truncate / hole punch) colliding with
     in-progress device-DMA. A fix for these collisions remains a
     work-in-progress pending resolution of truncate latency and
     starvation regressions.

   - The of_pmem driver expands the users of libnvdimm outside of x86
     and ACPI to describe an implementation of persistent memory on
     PowerPC with Open Firmware / Device tree.

   - Address Range Scrub (ARS) handling is completely rewritten to
     account for the fact that ARS may run for 100s of seconds and there
     is no platform defined way to cancel it. ARS will now no longer
     block namespace initialization.

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
