+HDQ/1w for OMAP platforms
+
+Required properties :
+- compatible : Must be "ti,am43xx-hdq".
+- ti,hwmods : Must be "hdq1w".
+- reg: Should contain register location and length.
+- interrupts: Should contain interrupt.
+- clock: Clock input to HDQ1w controller.
+
+Example:
+
+ hdq: hdq@48347000 {
+ compatible = "ti,am43xx-hdq";
+ reg = <0x48347000 0x1000>;
+ interrupts = <GIC_SPI 139 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&func_12m_clk>;
+ clock-names = "fck";
+ ti,hwmods = "hdq1w";
+ status = "disabled";
+ };
