Nokia N900: omap aes is broken

Hello,

I tried to test OMAP AES driver on Nokia N900 with special Nokia 
bootloader which enable L3 firewall for OMAP AES HW support.

I modified arch/arm/boot/dts/omap34xx-hs.dtsi file and commented 
aes line which disable aes support in DT.

Then I booted kernel and loaded omap-aes.ko module. And I got 
this output in dmesg:

[    0.222930] platform 480c5000.aes: Cannot lookup hwmod 'aes'
[   27.758148] omap-aes 480c5000.aes: _od_fail_runtime_resume: 
FIXME: missing hwmod/omap_dev info
[   27.765960] omap-aes 480c5000.aes: omap_aes_probe: failed to 
get_sync(-19)
[   29.257690] omap-aes 480c5000.aes: initialization failed.

So it looks like some initialization data are missing for Nokia 
N900 (omap3430 device).

Can somebody look at it? I have patched 2.6.28 kernel were omap 
aes support on this N900 device (with special bootloader) is 
working.

Maybe some other data are missing in DT or in hwmod?
