    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.
   14 
   15 Sub-nodes:
   16 - regulators : Contain the regulator nodes. The DA9052/53 regulators are
   17   bound using their names as listed below:

   23     ldo1      : regulator LDO1
   24     ldo2      : regulator LDO2
   25     ldo3      : regulator LDO3
   26     ldo4      : regulator LDO4
   27     ldo5      : regulator LDO5
   28     ldo6      : regulator LDO6
   29     ldo7      : regulator LDO7
   30     ldo8      : regulator LDO8
