3535 Due to above changes, Tegra114 I2C driver makes incompatible with
3636 previous hardware driver. Hence, tegra114 I2C controller is compatible
3737 with "nvidia,tegra114-i2c".
38
+ nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is on host1x bus
39
+ and is part of VE power domain and typically used for camera use-cases.
40
+ This VI I2C controller is mostly compatible with the programming model
41
+ of the regular I2C controllers with a few exceptions. The I2C registers
42
+ start at an offset of 0xc00 (instead of 0), registers are 16 bytes
43
+ apart (rather than 4) and the controller does not support slave mode.
3844 - reg: Should contain I2C controller registers physical address and length.
3945 - interrupts: Should contain I2C controller interrupts.
4046 - address-cells: Address cells for I2C device address.
