Note that T114 does not have a separate/different DVC (power I2C) controller like T20 - all 5 I2C controllers are identical, but I2C5 is used to designate the controller intended for power control (PWR_I2C in the schematics).

Only the Tegra114 value should be listed here; the presence of the Tegra30 value in the upstream kernel is a mistake that will be fixed as part of the Tegra114 clock driver patches.

Same here; only include the Tegra114 value since the HW isn't 100% compatible with the Tegra20 HW.

According to our downstream Linux kernel, that I2C controller can run up to 400KHz on this board.
