Changes in v11: - According to Yong's suggestion in [PATCH v10] to update patch - [PATCH 1/2]: Because keep ttbr u32, so the special logic of encoded PA bits[34:32] to ttbr lower bits will apply to all the MediaTek cases, not only for the quirk IO_PGTABLE_QUIRK_ARM_MTK_TTBR_EXT, so remove quirk check. - [PATCH 2/2]: Because no need calculate the special ttbr, so remove ttbr from mtk_iommu_domain and remove MMU_PT_ADDR_MASK calculate. Changes in v10: https://lore.kernel.org/linux-mediatek/20220616120713.12728-1-yf.wang@mediatek.com/ - According to Robin's suggestion in [PATCH v9] to update patch - Recovery ttbr to u32, encoded PA bits[34:32] to ttbr lower bits. - Remove PATCH: Rename MTK_IOMMU_TLB_ADDR to MTK_IOMMU_ADDR. Changes in v9: https://lore.kernel.org/linux-mediatek/20220615161224.6923-1-yf.wang@mediatek.com/ - According to Will's suggestion in [PATCH v8 1/3] update [PATCH 1/3] - Rename function to_iopte_mtk to to_mtk_iopte. - Modify gfp_l1 and slab_flag and add comment explaining. - Add checking that the address is within 35 bits use cfg->oas. - PATCH 1/3 & PATCH 2/3 no change. Changes in v8: https://lore.kernel.org/linux-mediatek/20220611102656.10954-1-yf.wang@mediatek.com/ - Add and update patch - Add [2/3] patch update MTK_IOMMU_ADDR to calculate the special ttbr. - Save the special ttbr to mtk_iommu_domain avoid calculate it again.

Changes in v6: - Update patch: gfp_l1 = GFP_KERNEL | __GFP_ZERO; - Update commit message for single normal zone. Changes in v5: - Only update message-ID. Changes in v4: - Fix build test WARNING: use GENMASK_ULL replace GENMASK. Changes in v3: - Add version changes description, there is No new code change in V3. Changes in v2: - Update patch and commit message - Add Level 1 pgtable PA up to 35bit. - This is new feature, remove stable@vger.kernel.org - Update commit message.
