1	* Marvell MMP I2C controller
2	
3	Required properties :
4	
5	 - reg : Offset and length of the register set for the device
6	 - compatible : should be "mrvl,mmp-twsi" where mmp is the name of a
7	   compatible processor, e.g. pxa168, pxa910, mmp2, mmp3.
8	   For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required
9	   as shown in the example below.
10	   For the Armada 3700, the compatible should be "marvell,armada-3700-i2c".
11	
12	Recommended properties :
13	
14	 - interrupts : the interrupt number
15	 - interrupt-parent : the phandle for the interrupt controller that
16	   services interrupts for this device. If the parent is the default
17	   interrupt controller in device tree, it could be ignored.
18	 - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
19	   status register of i2c controller instead.
20	 - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
21	
22	Examples:
23		twsi1: i2c@d4011000 {
24			compatible = "mrvl,mmp-twsi";
25			reg = <0xd4011000 0x1000>;
26			interrupts = <7>;
27			mrvl,i2c-fast-mode;
28		};
29		
30		twsi2: i2c@d4025000 {
31			compatible = "mrvl,mmp-twsi";
32			reg = <0xd4025000 0x1000>;
33			interrupts = <58>;
34		};
