[PATCH 01/13] soc/fsl/qman: fixup liodns only on ppc targets

From: laurentiu.tudor@nxp.com
Date: 2019-03-29 14:00:20
Also in: linux-arm-kernel, linux-iommu, lkml, netdev
Subsystem: freescale soc drivers, the rest · Maintainers: Christophe Leroy, Linus Torvalds

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.
