Merge tag 'staging-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging / IIO driver updates from Greg KH:
 "Here is the large set of staging and IIO driver updates for 5.10-rc1.

  Included in here are:

   - new IIO drivers

   - new IIO driver frameworks

   - various IIO driver fixes and updates

   - IIO device tree conversions to yaml

   - so many minor staging driver coding style cleanups

   - most cdev driver moved out of staging

   - no staging drivers added or removed

  Full details are in the shortlog.

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

+title: ADC on an STMPE multifunction device.
+
+maintainers:
+  - Stefan Agner <stefan@agner.ch>
+
+description:
+  This ADC forms part of an ST microelectronics STMPE multifunction device .
+  The ADC is shared with the STMPE touchscreen. As a result some ADC related
+  settings are specified in the parent node.
+  The node name myst be stmpe_adc and should be a child node of the stmpe node
+  to which it belongs.
