+SOCIONEXT Milbeaut Updown counter
+
+Required properties:
+- compatible: Must be "socionext,milbeaut-updown-counter".
+- reg: Offset and length of the device's register set.
+- clocks: Phandle to the clock used by the Updown counter module.
+- clock-names: Must be "mux".
+- interrupts: SPI number of the device's set.
+- cms_type: connected_device
+ 1: updown button (updown counter mode)
+ 2: rotary encoder (phase difference counter mode)
+
+Example:
+
+ updown0: updown@1e002000 {
+ compatible = "socionext,milbeaut-updown-counter";
+ reg = <0x1e002000 0x20>;
+ clocks = <&clk 4>;
+ clock-names = "mux";
+ interrupts = <0 104 0x4>;
+ cms_type = <1>;
+ };
