* Marvell MMP Interrupt controller

Required properties:
- compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or
"mrvl,mmp2-mux-intc"
- reg : Address and length of the register set of the interrupt controller.
If the interrupt controller is intc, address and length means the range
of the whold interrupt controller. If the interrupt controller is mux-intc,
address and length means one register. Since address of mux-intc is in the
range of intc. mux-intc is secondary interrupt controller.
- reg-names : Name of the register set of the interrupt controller. It's
only required in mux-intc interrupt controller.
- interrupts : Should be the port interrupt shared by mux interrupts. It's
only required in mux-intc interrupt controller.
- interrupt-controller : Identifies the node as an interrupt controller.
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source.
- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
controller.
- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
detection first.

Example:
intc: interrupt-controller@d4282000 {
compatible = "mrvl,mmp2-intc";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0xd4282000 0x1000>;
mrvl,intc-nr-irqs = <64>;

reg = <0x150 0x4>, <0x168 0x4>;
reg-names = "mux status", "mux mask";
mrvl,intc-nr-irqs = <2>;

- interrupts : Should be the port interrupt shared by all gpio pins.
There're three gpio interrupts in arch-pxa, and they're gpio0,
gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
gpio_mux.
- interrupt-name : Should be the name of irq resource. Each interrupt
binds its interrupt-name.
- interrupt-controller : Identifies the node as an interrupt controller.
- #interrupt-cells: Specifies the number of cells needed to encode an
interrupt source.
- gpio-controller : Marks the device node as a gpio controller.
- #gpio-cells : Should be one. It is the pin number.

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 : should be "mrvl,mmp-twsi" where mmp 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.
- interrupts : the interrupt number
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
services interrupts for this device. If the parent is the default
interrupt controller in device tree, it could be ignored.
- 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:
