-STMicroelectronics STM32 DAC
-
-The STM32 DAC is a 12-bit voltage output digital-to-analog converter. The DAC
-may be configured in 8 or 12-bit mode. It has two output channels, each with
-its own converter.
-It has built-in noise and triangle waveform generator and supports external
-triggers for conversions. The DAC's output buffer allows a high drive output
-current.

-Contents of a stm32 dac root node:
------------------------------------
-Required properties:
-- compatible: Should be one of:
- "st,stm32f4-dac-core"
- "st,stm32h7-dac-core"
-- reg: Offset and length of the device's register set.
-- clocks: Must contain an entry for pclk (which feeds the peripheral bus
- interface)
-- clock-names: Must be "pclk".
-- vref-supply: Phandle to the vref+ input analog reference supply.
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- resets: Must contain the phandle to the reset controller.
-- A pinctrl state named "default" for each DAC channel may be defined to set
- DAC_OUTx pin in mode of operation for analog output on external pin.
-
-Contents of a stm32 dac child node:
------------------------------------
-DAC core node should contain at least one subnode, representing a
-DAC instance/channel available on the machine.
-
-Required properties:
-- compatible: Must be "st,stm32-dac".
-- reg: Must be either 1 or 2, to define (single) channel in use
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in
- Documentation/devicetree/bindings/iio/iio-bindings.txt
-
-Example:
- dac: dac@40007400 {
- compatible = "st,stm32h7-dac-core";
- reg = <0x40007400 0x400>;
- clocks = <&clk>;
- clock-names = "pclk";
- vref-supply = <&reg_vref>;
- pinctrl-names = "default";
- pinctrl-0 = <&dac_out1 &dac_out2>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- dac1: dac@1 {
- compatible = "st,stm32-dac";
- #io-channels-cells = <1>;
- reg = <1>;
- };
-
- dac2: dac@2 {
- compatible = "st,stm32-dac";
- #io-channels-cells = <1>;
- reg = <2>;
- };
- };
