From 2ba93f8fa77c0140de163e8a31bb9c09b5ded74c Mon Sep 17 00:00:00 2001 From: Eero Nurkkala Date: Thu, 20 Aug 2009 16:18:17 +0300 Subject: OMAP: McBSP: Retain McBSP FCLK clockactivity FCLK may get autogated so that it prevents the McBSP to work properly. It is the bit 9 that must be set for maintaining the McBSP FCLK.
