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	
11	Recommended properties :
12	
13	 - interrupts : the interrupt number
14	 - interrupt-parent : the phandle for the interrupt controller that
15	   services interrupts for this device. If the parent is the default
16	   interrupt controller in device tree, it could be ignored.
17	 - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
18	   status register of i2c controller instead.
19	 - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
20	
21	Examples:
22		twsi1: i2c@d4011000 {
23			compatible = "mrvl,mmp-twsi";
24			reg = <0xd4011000 0x1000>;
25			interrupts = <7>;
26			mrvl,i2c-fast-mode;
27		};
28		
29		twsi2: i2c@d4025000 {
30			compatible = "mrvl,mmp-twsi";
31			reg = <0xd4025000 0x1000>;
32			interrupts = <58>;
33		};
34	
35	* Marvell MV64XXX I2C controller
36	
37	Required properties :
38	
39	 - reg             : Offset and length of the register set for the device
40	 - compatible      : Should be "marvell,mv64xxx-i2c"
41	 - interrupts      : The interrupt number
42	 - clock-frequency : Desired I2C bus clock frequency in Hz.
43	
44	Examples:
45	
46		i2c@11000 {
47			compatible = "marvell,mv64xxx-i2c";
48			reg = <0x11000 0x20>;
49			interrupts = <29>;
50			clock-frequency = <100000>;
51		};
