(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>; |
||||
}; |
