Subject: [PATCH 7/7] iommu/fsl: Added cache controller compatible strings for SOCs
Date: Mon, 7 Mar 2016 17:34:23 +0200	[thread overview]
Message-ID: <1457364863-18004-8-git-send-email-codrin.ciubotariu@nxp.com> (raw)
In-Reply-To: <1457364863-18004-1-git-send-email-codrin.ciubotariu@nxp.com>

From: Varun Sethi <Varun.Sethi@freescale.com>

Added cache controller compatible strings for T2080, B4420, T1040
and T1024. PAMU driver searches for a matching string while setting
up L3 cache stashing.
