Here below an example of device tree configuration used on standard DAVE's kit for the MITO 8M Mini:
From <code>imx8mm-mito8mmini.dtsdtsi</code>:
<pre>
&usbotg2 {
dr_mode = "host";
picophy,pre-emp-curr-control = <3>;
picophy,dc-vol-level-adjust = <7>;
status = "disabled";
};
...

From <code>imx8mm-mito8mmini-sbcx.dts</code>:
<pre>

/ {
regulators: regulators {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <0>;
reg_usb_pwr: usb_pwr {
compatible = "regulator-fixed";
regulator-name = "usb_pwr_en";
regulator-min-microvolt = <5000000>;

gpio = <&gpio1 12 GPIO_ACTIVE_HIGH>;
enable-active-high;
};
