ARM: OMAP4: hwmod data: add aes1
Browse files Browse the repository at this point in the history
This fixes the following error during kernel boot:

platform 4b501000.aes: Cannot lookup hwmod 'aes1'

Unfortunately the AES module is only documented partly
in the OMAP4430 TRM. I found an old patch from Joel,
which I took over and updated for currently mainline.
