9ce92da84f iio: imx7d_adc: Introduce a definition for the input clock
Since the input clock is always 24MHz, there is no need for storing
this value into a variable.

Use a definition instead, which is more appropriate in this case.

fe93116459 iio: imx7d_adc: Remove unneeded error message
In case of ioremap failure, the core code will take care of printing
the error message, so there is no need for having a local error
message in the driver.

936d3e536d iio:core: Fix bug in length of event info_mask and catch unhandled bits set in masks.
The incorrect limit for the for_each_set_bit loop was noticed whilst fixing
this other case.  Note that as we only have 3 possible entries a the moment
and the value was set to 4, the bug would not have any effect currently.
It will bite fairly soon though, so best fix it now.

See commit ef4b485659 ("iio:core: Fix bug in length of event info_mask and
catch unhandled bits set in masks.") for details.

The device dependent options which are going to be different for devices
which will be supported  in the future by this driver,
were moved in chip info for a more generic driver. This patch allows
supporting more devices by the driver. Also, it is an intermediate

Here is another set of reviewed patches that adds SPDX tags to different

 comments to try to determine that the license of the file is
 "GPL-2.0-or-later" or "GPL-2.0-only".  Only the "obvious" versions of
 these matches are included here, a number of "non-obvious" variants of
 text have been found but those have been postponed for later review and
 analysis.
 
 There is also a patch in here to add the proper SPDX header to a bunch
 of Kbuild files that we have missed in the past due to new files being
 added and forgetting that Kbuild uses two different file names for
 Makefiles.  This issue was reported by the Kbuild maintainer.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.

389fc70b60 iio: temperature: mlx90632 Relax the compatibility check
Register EE_VERSION contains mixture of calibration information and DSP
version. So far, because calibrations were definite, the driver
compatibility depended on whole contents, but in the newer production
process the calibration part changes. Because of that, value in EE_VERSION
will be changed and to avoid that calibration value is same as DSP version
the MSB in calibration part was fixed to 1.
That means existing calibrations (medical and consumer) will now have
hex values (bits 8 to 15) of 83 and 84 respectively. Driver compatibility
should be based only on DSP version part of the EE_VERSION (bits 0 to 7)
register.

e0dccbdf5a Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
 
 Lots of tiny fixes all over the staging and IIO driver trees here, along
 with some new IIO drivers.
 
 Also we ended up deleting two drivers, making this pull request remove a
 few hundred thousand lines of code, always a nice thing to see.  Both of
 the drivers removed have been replaced with "real" drivers in their
 various subsystem directories, and they will be coming to you from those
 locations during this merge window.
 
 There are some core vt/selection changes in here, that was due to some
 cleanups needed for the speakup fixes.  Those have all been acked by the
 various subsystem maintainers (i.e. me), so those are ok.
 
 We also added a few new drivers, for some odd hardware, giving new
 developers plenty to work on with basic coding style cleanups to come in
 the near future.
 
 Other than that, nothing unusual here.
 
 All of these have been in linux-next for a while with no reported
 issues, other than an odd gcc warning for one of the new drivers that
 should be fixed up soon.

Merge tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull pidfd updates from Christian Brauner:
 "This patchset makes it possible to retrieve pidfds at process creation
  time by introducing the new flag CLONE_PIDFD to the clone() system
  call. Linus originally suggested to implement this as a new flag to
  clone() instead of making it a separate system call.

  After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
  parent_tidptr argument. This means we can give back the associated pid
  and the pidfd at the same time. Access to process metadata information
  thus becomes rather trivial.

  As has been agreed, CLONE_PIDFD creates file descriptors based on
  anonymous inodes similar to the new mount api. They are made
  unconditional by this patchset as they are now needed by core kernel
  code (vfs, pidfd) even more than they already were before (timerfd,
  signalfd, io_uring, epoll etc.). The core patchset is rather small.
  The bulky looking changelist is caused by David's very simple changes
  to Kconfig to make anon inodes unconditional.

  A pidfd comes with additional information in fdinfo if the kernel
  supports procfs. The fdinfo file contains the pid of the process in
  the callers pid namespace in the same format as the procfs status
  file, i.e. "Pid:\t%d".

  To remove worries about missing metadata access this patchset comes
  with a sample/test program that illustrates how a combination of
  CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
  access to process metadata through /proc/<pid>.

  Further work based on this patchset has been done by Joel. His work
  makes pidfds pollable. It finished too late for this merge window. I
  would prefer to have it sitting in linux-next for a while and send it
  for inclusion during the 5.3 merge window"

5c25531d4b iio: adc: rcar-gyroadc: Remove devm_iio_device_alloc() error printing
devm_iio_device_alloc() can only fail due to a memory or IDA allocation
failure.  Hence there is no need to print a message, as the memory
allocation or IIO core code already takes care of that.

f1d8a071d4 counter: 104-quad-8: Add Generic Counter interface support
This patch adds support for the Generic Counter interface to the
104-QUAD-8 driver. The existing 104-QUAD-8 device interface should not
be affected by this patch; all changes are intended as supplemental
additions as perceived by the user.

Generic Counter Counts are created for the eight quadrature channel
counts, as well as their respective quadrature A and B Signals (which
are associated via respective Synapse structures) and respective index
Signals.

The new Generic Counter interface sysfs attributes are intended to
expose the same functionality and data available via the existing
104-QUAD-8 IIO device interface; the Generic Counter interface serves
to provide the respective functionality and data in a standard way
expected of counter devices.

The previous version of the chip was never released to customers
