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.
