-Marvell Berlin reset controller
-===============================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-The reset controller node must be a sub-node of the chip controller
-node on Berlin SoCs.
-
-Required properties:
-- compatible: should be "marvell,berlin2-reset"
-- #reset-cells: must be set to 2
-
-Example:
-
-chip_rst: reset {
-	compatible = "marvell,berlin2-reset";
-	#reset-cells = <2>;
-};
-
-&usb_phy0 {
-	resets = <&chip_rst 0x104 12>;
-};
