I plan to have the following:

tegra20.dtsi:

A regular device node for the pin controller, listing just the basic
device tree properties: "compatible" and "regs".

${board}.dts:

Each device node lists its pin mux/config setup using the bindings we
decide upon.

drivers/pinctrl/pinctrl-tegra20.c:

Static tables listing all pins, pin groups, mux functions, and pin
configuration options that Tegra supports.
