Dummy question ... CONFIG_LS2085A (and CONFIG_LS102XA) are board spezific defines, right? If so, I do not want them in driver specific code... because every board which uses this driver has to add here more defines. Could you introduce a SoC or at least a driver specific define here? Maybe CONFIG_SYS_I2C_MXC_I2C4 if no SoC specific code is possible ...
