[U-Boot] [PATCH v3 02/19] ARM: tegra: Guard clock code with a Kconfig symbol

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

Clock 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.
