Subject: [patch 2.6.27-rc6-omap 2/2] twl4030: board init updates
Date: Sun, 21 Sep 2008 14:12:23 -0700 [thread overview]
Message-ID: <200809211412.23342.david-b@pacbell.net> (raw)
For boards with twl4030/tps65950 chips, update board setup code to
provide the appropriate board info.
This should evolve a bunch more over time; right now too much of this
data is globally defined (like IRQ and GPIO numbering).
Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

NOTE: run-tested only on Beagle so far.
