This series adds support for Tegra256 I2C controllers to the Tegra I2C driver.

Tegra256 consists of 8 generic I2C controllers similar to previous Tegra generations,
but with a different parent clock frequency requiring adjusted timing parameters.

The changes add the "nvidia,tegra256-i2c" compatible string to device tree bindings
and implement the corresponding hardware feature structure with appropriate timing
parameters and clock divisors.

Hi Andi, Wolfram,

Do you want me to pick up the DT bindings patch? There's currently no DT
files that require this, so taking both through the I2C tree is fine,
but either way works for me.

Thanks,
Thierry
