Subject: [PATCH v10 15/23] iommu/mediatek: Move vld_pa_rng into plat_data
Date: Wed, 21 Aug 2019 21:53:18 +0800	[thread overview]
Message-ID: <1566395606-7975-16-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1566395606-7975-1-git-send-email-yong.wu@mediatek.com>

Both mt8173 and mt8183 don't have this vld_pa_rng(valid physical address
range) register while mt2712 have. Move it into the plat_data.
