From 0acce82b3dd792c85079ca1f4f7ffd8c82427e0a Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 3 Jun 2010 07:39:32 +0300 Subject: OMAP: McBSP: Function to query the FIFO size Users of McBSP can use the omap_mcbsp_get_fifo_size function to query the size of the McBSP FIFO. The function will return the FIFO size in words (the HW maximum).
