   1* Marvell MMP I2C controller
   2
   3Required 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
  11Recommended 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.

  21Examples:
  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        };
