-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.
