+Texas Instruments TWL family
+
+The TWLs are Integrated Power Management Chips.
+Some version might contain much more analog function like
+USB transceiver or Audio amplifier.
+These chips are connected to an i2c bus.
+
+
+Required properties:
+- compatible : Must be "ti,twl4030";
+ For Integrated power-management/audio CODEC device used in OMAP3
+ based boards
+- compatible : Must be "ti,twl6030";
+ For Integrated power-management used in OMAP4 based boards
+- interrupts : This i2c device has an IRQ line connected to the main SoC
+- interrupt-controller : Since the twl support several interrupts internally,
+ it is considered as an interrupt controller cascaded to the SoC one.
+- #interrupt-cells = <1>;
+
+Optional node:
+- Child nodes contain in the twl. The twl family is made of several variants
+ that support a different number of features.
+ The children nodes will thus depend of the capability of the variant.
+
+
+Example:
+/*
+ * Integrated Power Management Chip
+ * http://www.ti.com/lit/ds/symlink/twl6030.pdf
+ */
+twl@48 {
+ compatible = "ti,twl6030";
+ reg = <0x48>;
+ interrupts = <39>; /* IRQ_SYS_1N cascaded to gic */
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ interrupt-parent = <&gic>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ twl_rtc {
+ compatible = "ti,twl_rtc";
+ interrupts = <11>;
+ reg = <0>;
+ };
+};
