RE: [PATCH v2] OMAP3EVM: ehci: Fix EHCI support

[Bryan DE FARIA <bdefaria@adeneo-embedded.com>]

Hi Ajay,

TPS65950 GPIO2 is to choose through u131 if we drive the lines to the
evm mother board or to the expansion connector p18. Should not it be
default to the mother board?
The EHCI port on the mother board works with this patch.
