+* Marvell MMP I2C controller
+
+Required properties :
+
+ - reg : Offset and length of the register set for the device
+ - 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.
+ For the Armada 3700, the compatible should be "marvell,armada-3700-i2c".
+
+Recommended properties :
+
+ - interrupts : the interrupt number
+ - 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";
+ reg = <0xd4011000 0x1000>;
+ interrupts = <7>;
+ mrvl,i2c-fast-mode;
+ };
+
+ twsi2: i2c@d4025000 {
+ compatible = "mrvl,mmp-twsi";
+ reg = <0xd4025000 0x1000>;
+ interrupts = <58>;
+ };
