| Subject | [PATCH] ARM: tegra: Select appropriate DMA options for LPAE |
| Message-ID | <tzVhf-4Us-13@gated-at.bofh.it> |
This automatically selects options for zone DMA and 64 bit DMA addresses when LPAE is enabled on ARM Tegra platforms. These options are required for proper operation with LPAE enabled.
