(Placeholder note while we locate the kernel Tegra20 bindings)
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>;
};
