Define resources for McASP used on DA850/OMAP-L138 EVM, add platform device defintion and Pin Mux configurations.
Signed-off-by: Chaithrika U S chaithrika@ti.com
Applies on DaVinci GIT tree. This patch is dependent on the following patch which I have submitted earlier: [PATCH v2] ARM: DaVinci: Audio support for DA830 EVM
Pushed both to davinci git, and will queue for linux-next.
