* 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
|
|
|
