The common timing definition doesn't fully match the definition that is used by Tegra's Memory Controller, thus the DQS (data strobe) timing parameter is comprised of multiple sub-parameters that describe how to generate the strobe in hardware. There are also more additional parameters that are specific to Tegra and they are individually characterized for each memory model and clock rate. Hence the common timing definition isn't usable.
