[PATCH] pinctrl: tegra: expose config options for individual SoCs

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

I'm planning to remove CONFIG_ARCH_TEGRA_*_SOC, leaving just ARCH_TEGRA.
This will reduce the number of configurations that need to be supported
by core Tegra code, e.g. CPU idle, hotplug. As a precursor, we need to
update Kconfig for all Tegra drivers not to reference ARCH_TEGRA_*_SOC.

The Tegra pinctrl driver contains a fairly large amount of SoC-specific
code and data. Introduce explicit config options so that the user can
trim the set of supported SoCs if they wish. Default these to on, since
most people will probably want to enable support for all SoCs. This also
avoids the need to change any defconfig files.
