From 08905d8ab4d4a264c5a700b04b9cbafe4f381037 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 5 Mar 2012 11:27:40 +0200 Subject: [PATCH] ASoC: omap-mcbsp: Configure wakeup in later phase Configure the WAKEUPEN register at the same time we configure the rest of the McBSP registers. In case of OMAP3+, if the sysclock has been reconfigured we are going to disable McBSP for the duration of the clock change, which will reset the McBSP registers. The WAKEUPEN register need to be configured later, so the changes will be effective during runtime.
