Subject: [PATCH v3 19/24] iommu/mediatek: Support up to 34bit iova in tlb flush
Date: Wed, 30 Sep 2020 15:06:42 +0800	[thread overview]
Message-ID: <20200930070647.10188-20-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200930070647.10188-1-yong.wu@mediatek.com>

If the iova is 34bit, the iova[32][33] is the bit0/1 in the tlb flush
register. Add a new macro for this.

there is a minor change unrelated with this patch. it also use the new
macro.
