Merge tag 'char-misc-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-miscHEADmaster

Pull Char/Misc/IIO/others driver updates from Greg KH:
 "Here is the big set of char/misc/android/iio and other small driver
  subsystem patches for 7.4-rc1. Loads of stuff in here, larger than
  normal. Highlights include:

   - removal of the C binder code, the rust version is stable and will
     be used going forward in a few billion devices. Great job by those
     developers

   - loads and loads of IIO driver updates and feature additions

   - speakup driver fixes and updates

   - mhi driver updates

   - mei driver updates

   - xillybus driver fixes

   - comedi driver fixes

   - lots of coresight driver updates

   - Interconnect driver updates

   - nvmem driver updates and fixes

   - slimbus driver updates and fixes

   - spmi driver updates and fixes

   - lots of tiny misc and char driver fixes based on people scanning
     for things

  All of these have been in linux-next for a while with no reported
  issues, other than a merge conflict with one of the rust tree files,
  which should be simple to resolve"

+Description:
+		Read-only attribute containing the sysfs name prefix of the parent
+		channel for hierarchical channel relationships (e.g. "out_altvoltage0").
+		The prefix uniquely identifies the parent channel and can be used by
+		userspace to organize channels in tree-like structures that reflects
+		virtual or logical relationships between them.
+
+		For example, an IIO device may expose a primary output channel as
+		"out_voltage0" together with a set of profile-based or mode-based
+		subchannels used to configure or compose the output signal. These
+		subchannels may carry common attributes such as frequency, phase, etc.
+		They do not represent physical outputs, but rather logical/virtual
+		channels grouping configurations that affect the primary output.
+		Each subchannel exposes a <dir>_<type>[Y]_parent attribute reading
+		"out_voltage0", allowing userspace to group controls under the output
+		channel they belong to rather than treating them as unrelated top-level
+		channels.
