The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board.
