[U-Boot] [PATCH v3 05/19] ARM: tegra: Guard pin controller code with a Kconfig symbol

Thierry Reding
2019-03-21T18:01:04Z

Pin controller code is not relevant on all Tegra SoC generations, so
guard it with a Kconfig symbol that can be selected by the generations
that need it.

This is in preparation for unifying Tegra186 code with the code used on
older generations.
