Setting optional EBI/SMC properties through device tree always fails due to wrong evaluation of the return value of atmel_ebi_xslate_smc_timings(). If you put some of those properties in your dts file, but not 'atmel,smc-tdf-ns' the local variable 'required' in atmel_ebi_xslate_smc_timings() stays on 'false' after the first 'if' block. This leads to setting 'ret' to -EINVAL in the first run of the following 'for' loop which is then the return value of this function. However if you set 'atmel,smc-tdf-ns' in the dts file and everything in atmel_ebi_xslate_smc_timings() works well, it returns the content of 'required' which is 'true' then. So the function atmel_ebi_xslate_smc_timings() always returns non-zero which lets its call in atmel_ebi_xslate_smc_config() always fail and thus returning -EINVAL, so the EBI configuration for this node fails. Judging from the following code evaluating the local 'required' variable in atmel_ebi_xslate_smc_config() and the call of caps->xlate_config in atmel_ebi_dev_setup() it's probably right to only let the call fail if a negative error code is returned.
