@ suffix should be present only if reg property is present as well.
Otherwise a suffix separated with "-" should be used, like fixed-
regulator-0.

All these regulators should be made subnodes of a fixed-regulators node
aggregating all fixed regulators on the board, like on following example:
fixed-regulators {
avdd2: fixed-regulator-0 {
compatible = "regulator-fixed";
regulator-name = "avdd2-supply";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
};
cpvdd: fixed-regulator-1 {
compatible = "regulator-fixed";
regulator-name = "cpvdd-supply";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
};
/* ... */
};

Tomasz
