| 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: |
| 18 | |
| 19 | buck1 : regulator BUCK CORE |
| 20 | buck2 : regulator BUCK PRO |
| 21 | buck3 : regulator BUCK MEM |
| 22 | buck4 : regulator BUCK PERI |
| 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 |
| 31 | ldo9 : regulator LDO9 |
| 32 | ldo10 : regulator LDO10 |
| 33 | |
