This patch series is to convert existing OMAP DMA library into platform driver
for all the OMAP1 and OMAP2 plus processors as per alignment with
Benoit, Paul and Kevin.
The platform device model for OMAP2 plus will makes use of hwmod data base
and it is based on the reference branch:
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git
Branch: pm-wip/hwmods-omap4
commit f1c79ab452ed9cf7b5ff6488335c1ddf15d5c92a

OMAP4: hwmod: Enable omap_hwmod build for OMAP4
The proposal is to:
1. Convert DMA library into platform driver in hwmod way
2. Clean up API's to remove cpu_is_xxxx checks.
3. Make use of DMA engine(See Documentation/crypto/async-tx-api.txt)
This series is going to cover 1 & 2 and 3 will be taken up once these changes
becomes stable and thoroughly tested on all omap boards.
The API's are cleaned up to remove cpu_is_xxxx checks and code is moved
to corresponding respective mach-omap folders.
Basic tests are performed with this patch series on OMAP3630(Zoom3) board.
All other major defconfigs are build tested. OMAP4 boot seems to be broken
on above branch for both MMC and ethernet.
List of TODO's:
1. To perform more tests on OMAP4 once the branch is bootable.
2. OMAP2 boot and basic dma tests
It will be helpful is some one tests and provides feedback on OMAP1 and OMAP2
boards since I don't have OMAP1 board.
