| 1 | * Dialog Semiconductor SLG51000 Voltage Regulator | ||
| 2 | |||
| 3 | Required properties: | ||
| 4 | - compatible : Should be "dlg,slg51000" for SLG51000 | ||
| 5 | - reg : Specifies the I2C slave address. | ||
| 6 | - xxx-supply: Input voltage supply regulator for ldo3 to ldo7. | ||
| 7 | These entries are required if regulators are enabled for a device. | ||
| 8 | An absence of these properties can cause the regulator registration to fail. | ||
| 9 | If some of input supply is powered through battery or always-on supply then | ||
| 10 | also it is required to have these parameters with proper node handle of always | ||
| 11 | on power supply. | ||
| 12 | vin3-supply: Input supply for ldo3 | ||
| 13 | vin4-supply: Input supply for ldo4 | ||
| 14 | vin5-supply: Input supply for ldo5 | ||
| 15 | vin6-supply: Input supply for ldo6 | ||
| 16 | vin7-supply: Input supply for ldo7 | ||
| 17 | |||
| 18 | Optional properties: | ||
| 19 | - interrupt-parent : Specifies the reference to the interrupt controller. | ||
| 20 | - interrupts : IRQ line information. | ||
| 21 | - dlg,cs-gpios : Specify a valid GPIO for chip select | ||
| 22 | |||
| 23 | Sub-nodes: | ||
| 24 | - regulators : This node defines the settings for the regulators. | ||
| 25 | The content of the sub-node is defined by the standard binding | ||
| 26 | for regulators; see regulator.txt. | ||
| 27 | |||
| 28 | The SLG51000 regulators are bound using their names listed below: | ||
| 29 | ldo1 | ||
| 30 | ldo2 | ||
| 31 | ldo3 | ||
| 32 | ldo4 | ||
| 33 | ldo5 | ||
| 34 | ldo6 | ||
| 35 | ldo7 | ||
| 36 | |||
| 37 | Optional properties for regulators: | ||
| 38 | - enable-gpios : Specify a valid GPIO for platform control of the regulator. | ||
| 39 | |||
