   1 * Dialog DA9052/53 Power Management Integrated Circuit (PMIC)
   2
   3 Required properties:
   4 - compatible : Should be "dlg,da9052", "dlg,da9053-aa",
   5                          "dlg,da9053-ab", or "dlg,da9053-bb"
   6
   7 Optional properties:
   8 - dlg,tsi-as-adc : Boolean, if set the X+, X-, Y+, Y- touchscreen
   9                     input lines are used as general purpose analogue
  10                                         input.
  11 - tsiref-supply: Phandle to the regulator, which provides the reference
  12                  voltage for the TSIREF pin. Must be provided when the
  13                              touchscreen pins are used for ADC purposes.

  15 Sub-nodes:
  16 - regulators : Contain the regulator nodes. The DA9052/53 regulators are
  17   bound using their names as listed below:
