This patch set adds support for the tegra2 based ventana development board.                                                                           

Boot tested on ventana.

This patch splits out the common part of pinmux and GPIO initialization for
seaboard and derived boards. This code originates from chromeos kernel commit
772f1b56e713be7a55759c2d5eadb9eb11d078db. Author Jong Kim <jongk@nvidia.com>.

Add support for ventana pinmuxing as a seaboard derivative. This is a cut down
version of chromeos kernel commit 772f1b56e713be7a55759c2d5eadb9eb11d078db
by Jong Kim <jongk@nvidia.com>.

Hi,

The series looks reasonable to me, I'll apply it together with some of
the other pending tegra patches from the list. Once Stephen's pinmux
devicetree code is in place some of this can be removed.

One comment on this patch description though:

Having a reference to a SHA1 in a foreign source tree isn't really
useful in the mainline kernel commit log.

I would just phrase it "This is a cut down version of work done by <....>"

Ok. I will resend this series with the updated description.
