[PATCH 04/11] omap: musb: Pass board specific data from board file

Tony Lindgren tony at atomide.com
Fri Feb 19 18:30:21 EST 2010


From: Maulik Mankad <x0082077 at ti.com>

Pass board specific data for MUSB (like interface_type,
mode etc) from board file by defining board
specific structure.

Each board file can define this structure based on
its requirement and pass this information to the
driver.
