From 38698bef545403a334cf92153874bd06dc22cc66 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Wed, 23 Feb 2011 00:14:08 -0700 Subject: [PATCH] OMAP2+: clockevent: set up GPTIMER clockevent hwmod right before timer init MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Set up the GPTIMER hwmod used for the clockevent source immediately before it is used. This avoids the need to set up all of the hwmods until the boot process is further along. (In general, we want to defer as much as possible until late in the boot process.) This second version fixes a bug pointed out by Santosh Shilimkar , that would cause the kernel to use an incorrect timer hwmod name if the selected GPTIMER was not 1 or 12 - thanks Santosh. Also, Tarun Kanti DebBarma pointed out that the original patch did not apply cleanly; this has now been fixed.
