[alsa-devel] [PATCH v2] ARM: DaVinci: Audio support for DA830 EVM
Define resources for McASP1 used on DA830/OMAP-L137 EVM, add platform device defintion, initialization function. Additionally, this patch also adds version and FIFO related members to platform data structure.
Signed-off-by: Chaithrika U S chaithrika@ti.com --- Applies to DaVinci GIT tree. In this version of the patch, the init fucntion, resource and platform device definitions have neen moved to the devices-da8xx.c file.

Looks fine.
I'll merge these two 'ARM: DaVinci: *' patches via DaVinci git (after changing the subject prefix to just davinci:)
Merging them via davinci git will prevent conflicts in linux-next because these are touching code that is being changed from multiple directions.
