| STM32 VREFBUF - Voltage reference buffer |
| |
| Some STM32 devices embed a voltage reference buffer which can be used as |
| voltage reference for ADCs, DACs and also as voltage reference for external |
| components through the dedicated VREF+ pin. |
| |
| Required properties: |
| - compatible: Must be "st,stm32-vrefbuf". |
| - reg: Offset and length of VREFBUF register set. |
| - clocks: Must contain an entry for peripheral clock. |
| |
| Optional properties: |
| - vdda-supply: Phandle to the parent vdda supply regulator node. |
| |
| Example: |
| vrefbuf: regulator@58003c00 { |
| compatible = "st,stm32-vrefbuf"; |
| reg = <0x58003C00 0x8>; |
| clocks = <&rcc VREF_CK>; |
| regulator-min-microvolt = <1500000>; |
| regulator-max-microvolt = <2500000>; |
| vdda-supply = <&vdda>; |
| }; |
