Subject: [PATCH 0/2] i2c: tegra: Add Tegra256 I2C controller support

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.
