Merge tag 'omap-devel-a-for-3.10' of... 

Merge tag 'omap-devel-a-for-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.10/crypto

For OMAP2+ SoCs, convert the SHA/MD5 and AES accelerator integration
code and data to use hwmod and omap_device. This is a prerequisite for
moving the hwmod code out of arch/arm.

Basic test logs are available at:
