1 (Placeholder note while we locate the kernel Tegra20 bindings) 2 3 Added in U-Boot: 4 5 Required properties: 6 - clocks : Two clocks must be given, each as a phandle to the Tegra's 7 CAR node and the clock number as a parameter: 8 - the I2C clock to use for the peripheral 9 - the pll_p_out3 clock, which can be used for fast operation. This 10 does not change and is the same for all I2C nodes. 11 12 Example: 13 (TODO: merge with existing example): 14 15 i2c@7000c400 { 16 #address-cells = <1>; 17 #size-cells = <0>; 18 compatible = "nvidia,tegra20-i2c"; 19 reg = <0x7000C400 0x100>; 20 interrupts = < 116 >; 21 /* PERIPH_ID_I2C2, PLL_P_OUT3 */ 22 clocks = <&tegra_car 54>, <&tegra_car 124>; 23 }; 24
