Peter Ujfalusi b4c30df0eb ARM: dts: omap4-sdp: Make ethernet working even if booted with latest u-boot
The ethernet works in kernel only if we use some binary u-boot from the
past which have support for KS8851.

The u-boot sources are not available for this mysterious u-boot image
people tends to hold on... Mainline u-bott does not have ethernet support
for sdp4430 and if we use that the ethernet is not working.

After some debugging I have managed to get the ethernet working with
mainline u-boot while not breaking the networking with the case when we
boot with the mysterious binary u-boot.

Basically we were missing bunch of pinmux settings and the 'magic'
gpio_138 handling in kernel.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
