Perhaps the previous i2c8 enabling patch could be merged with this one.
For the floating sections, I suggest marking them as "not connected":
```
regulators {
buck1 {
regulator-min-microvolt = <500000>;
regulator-max-microvolt = <3450000>;
regulator-ramp-delay = <5000>;
regulator-always-on;
};
buck2 {
regulator-min-microvolt = <500000>;
regulator-max-microvolt = <3450000>;
regulator-ramp-delay = <5000>;
regulator-always-on;
};
buck3_1v8: buck3 {
regulator-min-microvolt = <500000>;
regulator-max-microvolt = <1800000>;
regulator-ramp-delay = <5000>;
regulator-always-on;
};
buck4_3v3: buck4 {
regulator-min-microvolt = <500000>;
regulator-max-microvolt = <3300000>;
regulator-ramp-delay = <5000>;
regulator-always-on;
};
