  1. (Placeholder note while we locate the kernel Tegra20 bindings)
  2. Added in U-Boot:
  3. Required properties:
  4. - clocks : Two clocks must be given, each as a phandle to the Tegra's
  5. CAR node and the clock number as a parameter:
  6. - the I2C clock to use for the peripheral
  7. - the pll_p_out3 clock, which can be used for fast operation. This
  8. does not change and is the same for all I2C nodes.
  9. Example:
  10. (TODO: merge with existing example):
  11. i2c@7000c400 {
  12. #address-cells = <1>;
  13. #size-cells = <0>;
  14. compatible = "nvidia,tegra20-i2c";
  15. reg = <0x7000C400 0x100>;
  16. interrupts = < 116 >;
  17. /* PERIPH_ID_I2C2, PLL_P_OUT3 */
  18. clocks = <&tegra_car 54>, <&tegra_car 124>;
  19. };
