Kernel-4.18.0-80.el8_da9052-i2c

• 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

  The bindings details of individual regulator device can be found in:
  Documentation/devicetree/bindings/regulator/regulator.txt
