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

          does not change and is the same for all I2C nodes.
