[alsa-devel] [PATCH 2/2] [RFC] da850evm: enable mcasp ping-pong buffers

[Ben Gardiner]

The davinci--mcasp driver will copy the platform data specified
sram_size's and eventq's.

Set the eventq's and sram size for da850 and disable CONFIG_SUSPEND
so that there is SRAM enough left for the McASP (until the patch to allocate
sram from the 128K shared RAM region, then there should be plenty to spare)
