Comment 3 Tobias Jakobi 2014-05-01 11:44:41 UTC
Closing this, since the error doesn't occur on 3.15.0-rc3 anymore.

Still, AES hw doesn't work yet:
platform 4b501000.aes: Cannot lookup hwmod 'aes'
omap-aes 4b501000.aes: _od_fail_runtime_resume: FIXME: missing hwmod/omap_dev info
omap-aes 4b501000.aes: omap_aes_probe: failed to get_sync(-19)
omap-aes 4b501000.aes: initialization failed.
