Subject: [PATCH v8 2/7] iommu/mediatek: Set dma_mask for PGTABLE_PA_35_EN
Date: Tue, 7 Mar 2023 16:05:50 +0800 [thread overview]
Message-ID: <20230307080555.14399-3-yong.wu@mediatek.com> (raw)
In-Reply-To: <20230307080555.14399-1-yong.wu@mediatek.com>
When we enable PGTABLE_PA_35_EN, the PA for pgtable may be 35bits.
Thus add dma_mask for it.
Fixes: 301c3ca12576 ("iommu/mediatek: Allow page table PA up to 35bit")
