+- gpio-controller : Marks the device node as a gpio controller.

+* I2C
+
+Required properties :
+
+ - reg : Offset and length of the register set for the device
+ - compatible : should be "mrvl,mmp-twsi" where CHIP is the name of a
+   compatible processor, e.g. pxa168, pxa910, mmp2, mmp3.
+   For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required
+   as shown in the example below.
+
+Recommended properties :
+
+ - interrupts : <a b> where a is the interrupt number and b is a
+   field that represents an encoding of the sense and level
+   information for the interrupt.  This should be encoded based on
+   the information in section 2) depending on the type of interrupt
+   controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+   services interrupts for this device.
+ - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
+   status register of i2c controller instead.
+ - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
+
+Examples:
+	twsi1: i2c@d4011000 {
+		compatible = "mrvl,mmp-twsi", "mrvl,pxa-i2c";
+		reg = <0xd4011000 0x1000>;

+		mrvl,i2c-fast-mode;

+* Marvell Real Time Clock controller
+
+Required properties:
+- compatible: should be "mrvl,sa1100-rtc"
+- reg: physical base address of the controller and length of memory mapped

+- interrupts: Should be two. The first interrupt number is the rtc alarm

+Example:
