[PATCH 46/94] ARM: dts: am335x-evm: Enable the McASP FIFO for audio

From: Sam Asadi
Date: Tue Jul 15 2014 - 13:04:15 EST


From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>

The use of FIFO in McASP can reduce the risk of audio under/overrun and
lowers the load on the memories since the DMA will operate in bursts.
