I guess Stephen's idea is to retrieving the function name and group name
From the pinctrl driver since Tagre prefers to define those things in driver
Rather than in board file or soc.dts file.
But it does not fit for IMX since we define it in soc.dts.

Hmm, when he came up with this proposal and said it should work for
Tegra, I assume he plans to move those from Tegra pinctrl driver into
device tree.  Stephen?

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.
