From 1c20a5420c2602e2438209f34a633eae377eda5e Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 19 Feb 2015 23:43:32 +0100 Subject: [PATCH] mpc85xx: add mpic timer clock frequency MPIC timers are enabled in the config, however a devicetree clock setting is missing causing the following error: /soc@ffe00000/timer@41100: cannot get timer frequency. /soc@ffe00000/timer@42100: cannot get timer frequency. This patch adds the missing clock and avoids the error. It's a functional copy of this code do_fixup_by_compat_u32(blob, "fsl,mpic", "clock-frequency", get_bus_freq(0), 1); in arch/powerpc/cpu/mpc85xx/fdt.c in the u-boot code.
