Hmm, some clock node is broken, might be missing a name or parent
name for some reason. Can you try to boot with DEBUG enabled so you
get pr_debug:s out and see which clock is being initialized during
the crash?
...

...
We really should be registering the clocks lazily as needed BTW. That
leaves out the dependency to DEBUG_LL for seeing any kind of decent
error messages during the booting.

Hey Tony,
Can you retry with the branch? I just pushed one patch there, seems
the parents for the vlynq_mux_fck were somewhat broken (there are
holes in the valid mux values list, which hasn't happened with any
other mux-clock so far.)
If this works, I will rework the series a bit and send v2 out.
Alternatively I need to add extra debug info.
Still getting this without omap3:
drivers/built-in.o: In function `of_ti_dpll_setup':
/home/tmlind/src/linux-2.6/drivers/clk/ti/dpll.c:235: undefined reference to `clkhwops_omap3_dpll'

drivers/built-in.o:(.rodata+0x1d860): undefined reference to `omap3_noncore_dpll_set_rate'
and after enabling omap3 getting this without 2430:
drivers/built-in.o: In function `of_ti_omap2430_interface_clk_setup':
/home/tmlind/src/linux-2.6/drivers/clk/ti/interface.c:129: undefined reference to `clkhwops_omap2430_i2chs_wait'
Yea, I didn't fix these with the patch I pushed, just the boot problem.
I will fix these with the next version of the set, in addition to the
issues reported by Nishanth.
But after enabling those, it now boots on n8x0. The dmesg is below.
This is good, so the culprit was only the vlynq fck.
Care to post a patch to try dropping the legacy clock data as it should
now work with the DT clocks only for omap2?
Yes, I can post patches for this for omap2/omap3 also tomorrow.
