+* Maxim MAX7360 Multi-function Device
+
+The Maxim MAX7360 is a Multi-function Device which includes
+64 key switches, 8 LED drivers/GPIOs, PWM intensity control,
+and rotary switch control.
+
+Required properties:
+- compatible: Should be the following: "maxim,max7360".
+- reg: Specifies the I2C slave address of the max7360 block.
+ It can be 0x38, 0x3a, 0x3c or 0x3e IIUC.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to
+ which the interrupts from MAX7360 are routed to.
+- interrupts: List of IRQ lines specifiers.
+- interrupt-names: List of "inti" and "intk".
+- interrupt-controller: Identifies the device as an interrupt
controller.
+- #interrupt-cells : Number of cells to encode an interrupt source,
+ shall be 1.
+
+Examples:
+
+Without subnodes:
+ max7360@38 {
+ compatible = "maxim,max7360";
+ reg = <0x38>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <23 IRQ_TYPE_LEVEL_LOW>, <23 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-names = "inti", "intk";
+ interrupt-controller;
+ #interrupt-cells = <0x1>;
+ };
+
+With subnodes:
+ max7360@38 {
+ compatible = "maxim,max7360";
+ reg = <0x38>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <23 IRQ_TYPE_LEVEL_LOW>, <23 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-names = "inti", "intk";
+ interrupt-controller;
+ #interrupt-cells = <0x1>;
+
+ gpio {
+ compatible = "maxim,max7360-gpio";
+ gpio-controller;
+ #gpio-cells = <0x2>;
+ interrupt-controller;
+ #interrupt-cells = <0x2>;
+ interrupts = <0>;
+ };
+
+ keypad {
+ compatible = "maxim,max7360-keypad";
+ maxim,debounce_reg = /bits/ 8 <0xef>;
+ maxim,ports_reg = /bits/ 8 <0xae>;
+ linux,keymap = < MATRIX_KEY(0, 0, KEY_F5)
+ MATRIX_KEY(1, 0, KEY_F4) >;
+ keypad,num-rows = <2>;
+ keypad,num-columns = <1>;
+ interrupts = <1>;
+ };
+
+ pwm {
+ compatible = "maxim,max7360-pwm";
+ #pwm-cells = <0x2>;
+ };
+
+ rotary-encoder {
+ compatible = "maxim,max7360-rotary";
+ interrupts = <2>;
+ };
+
+ };
