··· 35 35 Due to above changes, Tegra114 I2C driver makes incompatible with 36 36 previous hardware driver. Hence, tegra114 I2C controller is compatible 37 37 with "nvidia,tegra114-i2c". 38 - nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is part of the 39 - host1x domain and typically used for camera use-cases. This VI I2C 40 - controller is mostly compatible with the programming model of the 41 - regular I2C controllers with a few exceptions. The I2C registers start 42 - at an offset of 0xc00 (instead of 0), registers are 16 bytes apart 43 - (rather than 4) and the controller does not support slave mode. 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.
