Subject: [PATCH 01/13] soc/fsl/qman: fixup liodns only on ppc targets
Date:   Fri, 29 Mar 2019 16:00:02 +0200
Message-Id: <20190329140014.8126-2-laurentiu.tudor@nxp.com>
In-Reply-To: <20190329140014.8126-1-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.
