I get this too.
Any clues?
Reverting 665d001338b494d6d62810aa99b4c0fa1a0884b9 "OMAP2+: hwmod:
Follow the recommended PRCM module enable sequence" fixes this for me.
More specifically, this hunk alone seems to do the trick:
diff --git a/arch/arm/mach-omap2/clock44xx_data.c b/arch/arm/mach-omap2/clock44x

for (c = omap44xx_clks; c< omap44xx_clks + ARRAY_SIZE(omap44xx_clks);
c++)
I'm not suggesting this is anyway near a real fix, but hopefully it
will help pin-point the problem (clock44xx_data.c changes ?).
Even I am seeing same and bit similar crash in omap4 sdp
All of these are symptoms of your driver accessing registers
while the module is not fully enabled. This is because clock
framework on OMAP4, neither puts the respective clockdomains
in right state before enabling the clocks, nor does it wait
on IDLEST bits to make sure the module is completely accessible.
All of this is moved into higher level hwmod/omap_device frameworks,
and hence a runtime PM conversion of your driver should fix all these
issues.
