Pull char/misc/IIO/etc driver updates from Greg KH:
 "Here is the big set of char, misc, iio, counter, fpga, and other small
  driver subsystems for 7.3-rc1.

  Overall, due to some driver removals we only added a bit more code
  than removed, which was a nice change. Highlights in this merge
  request are:

   - Loads of IIO driver updates and additions

   - binder driver updates (more on that below...)

   - Removal of the SGI XP and GRU drivers as they are not used anymore
     and turn out to be pretty insecure overall

   - Removal of the obsolete ibmasm driver as it's not being used
     anymore

   - Coresight driver updates and additions

   - Mei driver udpates

   - Counter driver updates

   - FPGA driver updates

   - ICC driver updates

   - lots and lots of other tiny driver updates to resolve reported
     issues

  All of these have been in linux-next for a while"

  specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc
- Add RV1106 which is compatible with the RV3588.

Features
--------

buffer-dmaengine
- Allow cyclic buffers, useful for repeating sequence generation with DACs.

Cleanups, minor fixes
---------------------

Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.

Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
  mark_last_busy part inside the put, these provide no useful code
  deduplication or readability advantages over directly calling the
  runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
  info for deferred probe debugging.
- Drop some redundant error prints where the called function already
  provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
  improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. Often part of a more significant series.
- Remove abstractions designed to allow a driver to support multiple device
  types, when they have been around a long time and only the original part
  showed up.
- Initialize spi_device_id arrays using member names following dropping of
  driver data from drivers that didn't actually use it.
- Catch up with i2c_device_id tables added since previous effort to use
  named initializers for all those.
- Use kernel types in a few places instead of standard C ones or bare
  unsigned.

Misc
- Update Xilinx AMS maintainer.
- Update email address for Maxwell Doose.
- Update email address for Siratul Islam.
- Update email address for Tomasz Duszynski and re-add Tomasz to
  various maintainer entries.
Docs
- Encourage use of differential channel naming even when there is no
  flexibility in input to differential pair mapping. Intended to
  provide a strong signal to userspace that a channel is differential.
adi,ad_sigma_delta
- Allow COMPILE_TEST without any users.
adi,ad2s1201
- Refactor trigger handler to avoid mix of guard() and goto.
adi,ad5686
- Avoid potential NULL dereference is user forces a driver bind.
adi,ad5696
- Add a couple of missing entries to the of_match_id table and update
  binding to match.

  the setup is done to avoid potentially dropping data.
honeywell,abp2030pa
- Drop an unreachable return.
invensens,icm45600
- Harden against bad value of FIFO sample count from device.
- Use i2c_match_data if firmware table sourced match data isn't available.
nxp,mpl1115
- Ensure runtime_pm is balanced on error in probe.
rohm,bm1390
- Make the driver slightly more likely to recover from transient errors.
sensiron,sgp30
- Handle thread creation errors.
st,lsm6dsx
- Update the enable mask when doing sensor fusion to avoid incorrect fifo
  data handling.
st,stm32-dfsdm
- Treat dt flags as booleans.
ti,ads1015
- Switch to devm helpers which simplified code and closed a resource leak.
ti,opt3001
- Split complicated opt3001_get_processed() logic into irq an no irq
  helper functions.
- Use devm to simplify code.
- Use guard() to simplify code.
- Reorder probe so final call exposes userspace interfaces.

pdata->core_data is allocated in init_temp_data() when the first core
temp_data of a package is created, but it is only released from
destroy_temp_data(), and only in the branch that handles the package
temp_data.

Package temp_data is created solely when the CPU supports
X86_FEATURE_PTS. On a CPU without it, coretemp_cpu_online() never calls
coretemp_add_core() with pkg_flag set, so pdata->pkg_data stays NULL.
coretemp_cpu_offline() then skips the removal of the package interface,
destroy_temp_data() is never called for package data, and the array is
still allocated when coretemp_device_remove() frees the platform data
that pointed at it.

Release the array in coretemp_device_remove(). destroy_temp_data() sets
pdata->core_data to NULL when it frees it, so the added kfree() is a
no-op on CPUs that do have PTS.

Tested on an Intel Core i5-1135G7. The driver was instrumented to log
every allocation and release of pdata->core_data, and the PTS check in
coretemp_cpu_online() was patched out to emulate a CPU without package
thermal support. Without this change the array was allocated and never
released, and coretemp_device_remove() still saw a non-NULL pointer.
With it the array is released and the pointer accounting balances. On an
unmodified build the release still happens via the package temp_data and
the added kfree() sees NULL, with no slab warnings over repeated module
load and unload cycles.

max6621_read() reads the CONFIG2 offset and the critical alert threshold
registers into a u32 and scales them without sign extension:

	/* offset */ *val = (regval >> MAX6621_REG_TEMP_SHIFT) * 1000L;
	/* crit   */ *val = regval * 1000L;

Both attributes are writable and their write paths clamp to a negative
minimum and encode negative values, so a value written as negative is read
back as a large positive number. For example, writing a -10 degrees C
offset stores max6621_temp_mc2reg(-10000) = (-10 << 6) = 0xfd80; the read
then computes 0xfd80 >> 6 = 1014 -> 1014000 instead of -10000.

Cast the register value to s16 before scaling so the read preserves the
sign the write path encodes. The temperature input path already uses an s8
intermediate and is left unchanged.

MAX6621_TEMP_INPUT_MIN and MAX6621_TEMP_INPUT_MAX are used to clamp the
writable offset and critical thresholds. They are defined as -127000 and
128000.

The driver decodes the temperature through an s8 and its own comment in
max6621_read() documents an 8-bit two's complement value, whose range is
-128 to +127 degrees C. The current limits therefore reject the valid
-128 degrees C and accept +128 degrees C, which does not fit the 8-bit
range.

Correct the limits to -128000 and 127000.
