Simon (and Tomeu),
Can you comment on this change? If the data currently in
tegra-pinmux-scripts is wrong, where did it come from if not the ChromeOS
kernel?
Sorry, I have no direct knowledge.
Oh, I see the answer in the patch description:
commit 4a5373e4bd6477addd3764e25989f74d34eba8c6

Add support for Nyan-big
Add support for Tegra124 Nyan-big. Pinmux is based on norrin with a single
change for the reset GPIO.
The need for Daniel's patch seems like a good reason not to base one
board's pinmux on another board, assuming they're identical...
Daniel, have you confirmed that 100% of the data in your patch matches
that used by the ChromeOS kernel, such that there shouldn't be any more
fixes needed down the line?
