* Dialog DA9052/53 Power Management Integrated Circuit (PMIC)

Required properties:
- compatible : Should be "dlg,da9052", "dlg,da9053-aa",
			 "dlg,da9053-ab", or "dlg,da9053-bb"

Optional properties:
- dlg,tsi-as-adc : Boolean, if set the X+, X-, Y+, Y- touchscreen
                    input lines are used as general purpose analogue
					input.
- tsiref-supply: Phandle to the regulator, which provides the reference
                 voltage for the TSIREF pin. Must be provided when the
			     touchscreen pins are used for ADC purposes.

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

    buck1     : regulator BUCK CORE
    buck2     : regulator BUCK PRO
    buck3     : regulator BUCK MEM
    buck4     : regulator BUCK PERI
    ldo1      : regulator LDO1
    ldo2      : regulator LDO2
    ldo3      : regulator LDO3
    ldo4      : regulator LDO4
    ldo5      : regulator LDO5
    ldo6      : regulator LDO6
    ldo7      : regulator LDO7
    ldo8      : regulator LDO8
    ldo9      : regulator LDO9
    ldo10     : regulator LDO10
