   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.

  22         twsi1: i2c@d4011000 {
  23                 compatible = "mrvl,mmp-twsi";
  24                 reg = <0xd4011000 0x1000>;
  25                 interrupts = <7>;
  26                 mrvl,i2c-fast-mode;
  27         };

  29         twsi2: i2c@d4025000 {
  30                 compatible = "mrvl,mmp-twsi";
  31                 reg = <0xd4025000 0x1000>;
  32                 interrupts = <58>;
