Subject: [PATCH v3 01/22] soc/fsl/qman: fixup liodns only on ppc targets
Date:   Wed, 10 Oct 2018 15:07:19 +0300
Message-Id: <20181010120737.30300-2-laurentiu.tudor@nxp.com>
In-Reply-To: <20181010120737.30300-1-laurentiu.tudor@nxp.com>
References: <20181010120737.30300-1-laurentiu.tudor@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
