    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  - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
   16    status register of i2c controller instead.
   17  - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
   18 
   19 Examples:
   20         twsi1: i2c@d4011000 {
   21                 compatible = "mrvl,mmp-twsi";
   22                 reg = <0xd4011000 0x1000>;
   23                 interrupts = <7>;
   24                 mrvl,i2c-fast-mode;
   25         };
   26         
   27         twsi2: i2c@d4025000 {
   28                 compatible = "mrvl,mmp-twsi";
   29                 reg = <0xd4025000 0x1000>;
   30                 interrupts = <58>;
   31         };
