Hi all,
Here are few patches to make it easier for us to maintain
legacy platform data support while moving to device
tree based booting. It seems that we still have quite a
few places where we still need platform data for omap3
to keep things from breaking.
As the remaining drivers get converted to use device tree,
we can then just remove the support from the pdata-quirks.c.
Regards,
Tony

We want to drop the board-*.c files but keep things working.
Let's make it a bit easier to support legacy platform data
init with quirks. This also keeps board-generic.c clean from
board specific hacks.
For now, the quirks table is empty, that is populated
in the later patches.

Let's use the platform data quirk support for wl12xx
and move the board specific code out of devices.c.

This should be legacy_init_wl12xx(unsigned ref_clock,
unsigned tcxo_clock, int gpio) instead of just
omap_init_wl12xx_of(void).
I've updated the patch and pushed this series to
omap-for-v3.13/quirk.
Regards,
Tony
