- 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>;
interrupts = <7>;
mrvl,i2c-fast-mode;
};
twsi2: i2c@d4025000 {
compatible = "mrvl,mmp-twsi", "mrvl,pxa-i2c";
reg = <0xd4025000 0x1000>;
interrupts = <58>;

* 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
region.
- interrupts: Should be two. The first interrupt number is the rtc alarm
interrupt and the second interrupt number is the rtc hz interrupt.
- interrupt-names: Assign name of irq resource.
Example:
rtc: rtc@d4010000 {
compatible = "mrvl,mmp-rtc";
reg = <0xd4010000 0x1000>;
interrupts = <5>, <6>;
interrupt-name = "rtc 1Hz", "rtc alarm";
