Dnvidia,tegra20-i2c.txt1 NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
4 - compatible : For Tegra20, must be one of "nvidia,tegra20-i2c-dvc" or
5 "nvidia,tegra20-i2c". For Tegra30, must be "nvidia,tegra30-i2c".
6 For Tegra114, must be "nvidia,tegra114-i2c". Otherwise, must be
7 "nvidia,<chip>-i2c", plus at least one of the above, where <chip> is
10 nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
11 controller. This only support master mode of I2C communication. Register
12 interface/offset and interrupts handling are different than generic I2C
13 controller. Driver of DVC I2C controller is only compatible with
14 "nvidia,tegra20-i2c-dvc".
