Subject: ARM: tegra: Guard GP pad control code with a Kconfig symbol
X-Git-Tag: v2019.07-rc4~4^2~19
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=9e57819294a1b2b247f66a6dbfa380137e166ec5;p=oweals%2Fu-boot.git

ARM: tegra: Guard GP pad control code with a Kconfig symbol

The GP pad control 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.
