From bdcc61275232db897ba831f87a16df98ab248571 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 18 Jan 2013 16:48:16 -0700 Subject: [PATCH] ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls During the migration to the common clock framework, calls to the functions omap2xxx_clkt_vps_late_init() were not preserved for OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found. "Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the OMAP2420 and OMAP2430 clock initialisation code.
