[PATCH] iommu/tegra-smmu: Fix tlb_mask

2020-09-15 Thread Nicolin Chen
The "num_tlb_lines" might not be a power-of-2 value, being 48 on Tegra210 for example. So the current way of calculating tlb_mask using the num_tlb_lines is not correct: tlb_mask=0x5f in case of num_tlb_lines=48, which will trim a setting of 0x30 (48) to 0x10. Signed-off-by: Nicolin Chen --- dri
