From: Laurentiu Tudor <laurentiu.tudor@nxp.com> ARM SoCs use SMMU so the liodn fixup done in the qman driver is no longer making sense and it also breaks the ICID settings inherited from u-boot. Do the fixups only for PPC targets. Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> --- drivers/soc/fsl/qbman/qman_ccsr.c | 2 ++ 1 file changed, 2 insertions(+)
