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.
