This series adds the ability to late-initialize individual
hwmods. The goal here is for clockevent (and eventually
clocksource) hwmods to be late-initialized individually, and
right before they are needed, in the timer init code. Then
omap_hwmod_late_init(), which late-inits the rest of the hwmods,
is intended to run as an initcall -- much later in the boot
process.
This series includes the OMAP2/3 hwmod data for the GPTIMERs that
Tarun posted earlier. This data is necessary for this new code
to avoid warnings during boot.
Boot-tested on N800, OMAP34xx Beagleboard and OMAP4430ES2 Panda.
I'm testing it on 4430sdp, and I have the following warning:
[ 0.000000] omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for

This is due to commit 3b03b58dab847883e6b9a431558c7d8e43fa94c6 ("OMAP4:
hwmod data: Prevent timer1 to be reset and idle during init"). Could you
please try reverting this and see if the warning disappears?
Thanks, this is indeed fixing this warning. I didn't see these two
patches were exclusive.
Thanks,
Benoit
Tony, I guess the omap-for-linus branch will probably need to get rebuilt
to drop that patch, once this series is merged...
