 "CrOS EC / MFD / IIO:

   - Contains tag-ib-chrome-mfd-iio-input-5.5, which is the first part
     of a series from Gwendal to refactor sensor code between MFD, CrOS
     EC, iio and input in order to add a new sensorhub driver and FIFO
     processing

  Wilco EC:

   - Add support for Dell's USB PowerShare policy control, keyboard
     backlight LED driver, and a new test_event file.

   - Fixes use after free in wilco_ec's telemetry driver.

  Misc:

   - bugfix in cros_usbpd_logger (missing destroy workqueue)"

+Description:
+               Control the USB PowerShare Policy. USB PowerShare is a policy
+               which affects charging via the special USB PowerShare port
+               (marked with a small lightning bolt or battery icon) when in
+               low power states:
+               - In S0, the port will always provide power.
+               - In S0ix, if usb_charge is enabled, then power will be
+                 supplied to the port when on AC or if battery is > 50%.
+                 Else no power is supplied.
+               - In S5, if usb_charge is enabled, then power will be supplied
+                 to the port when on AC. Else no power is supplied.
+
+               Input should be either "0" or "1".
