|
Added in U-Boot:
|
|
|
|
Required properties:
|
|
- clocks : Two clocks must be given, each as a phandle to the Tegra's
|
|
CAR node and the clock number as a parameter:
|
|
- the I2C clock to use for the peripheral
|
|
- the pll_p_out3 clock, which can be used for fast operation. This
|
|
does not change and is the same for all I2C nodes.
|
|
|
|
Example:
|
|
(TODO: merge with existing example):
|
|
|
|
i2c@7000c400 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "nvidia,tegra20-i2c";
|
|
reg = <0x7000C400 0x100>;
|
|
interrupts = < 116 >;
|
|
/* PERIPH_ID_I2C2, PLL_P_OUT3 */
|
|
clocks = <&tegra_car 54>, <&tegra_car 124>;
|
|
};
