Hi,

It seems,
"[PATCH v4 02/11] ARM: OMAP2+: hwmod: AM335x/AM43x: move common data"
is held on LAKML for moderator approval due to big size.

I will wait for some time to see if moderator approves, if not, will
ping him (believe it is David Woodhouse), but not sure how to get it
into omap list though.

Changes are also available
@git://gitorious.org/x0148406-public/linux-kernel.git tags/am43x-prcm-v4

Regards
Afzal
