I'd suggest naming those tegra20_*.

... and that tegra114_spi. That way, it's obvious when those IP blocks
were introduced, which will help people know which driver they care about.

Looking closer at the Tegra114 TRM, it looks like they did declare
"slink" a deprecated name, so the Tegra114 block really should be called
"SPI" as you have it. So, disregard my comments about the compatible
value; nvidia,tegra114-spi looks like the correct choice now.
