Merge tag 'acpi-6.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull more ACPI updates from Rafael Wysocki:
 "These add two ACPI-related quirks and extend support for Apple device
  properties supplied via ACPI _DSM.

  Specifics:

   - Do not turn off unused power resources during initialization on the
     Toshiba Click Mini (Hans de Goede)

   - Support strings in device properties supplied by ACPI _DSM on Apple
     platforms (Hector Martin)

   - Add an ACPI device ID quirk for Lenovo Yoga Tablet 2 (Marius Hoch)"
