[alsa-devel] [PATCH 2/2] davinci: da850evm: enable mcasp ping-pong bufs and evq's

[Ben Gardiner]

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

Set the event queues and sram sizes for da850. 8K SRAM buffers are selected
because it is the minimum that resulted in the same period size when testing
48KHz S16_LE stereo. Event queues 0 and 1 are assigned to match those 
specified by Troy Kisky in his introduction of ping-pong buffers for dm644x.
