  1. * Marvell MMP I2C controller
  2. Required properties :
  3. - reg : Offset and length of the register set for the device
  4. - compatible : should be "mrvl,mmp-twsi" where mmp is the name of a
  5. compatible processor, e.g. pxa168, pxa910, mmp2, mmp3.
  6. For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required
  7. as shown in the example below.
  8. For the Armada 3700, the compatible should be "marvell,armada-3700-i2c".
  9. Recommended properties :
  10. - interrupts : the interrupt number
  11. - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
  12. status register of i2c controller instead.
  13. - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
  14. Examples:
  15. twsi1: i2c@d4011000 {
  16. compatible = "mrvl,mmp-twsi";
  17. reg = <0xd4011000 0x1000>;
  18. interrupts = <7>;
  19. mrvl,i2c-fast-mode;
  20. };
  21. twsi2: i2c@d4025000 {
  22. compatible = "mrvl,mmp-twsi";
  23. reg = <0xd4025000 0x1000>;
  24. interrupts = <58>;
  25. };
