| 2 | |
| 3 | Required properties: |
| 4 | - compatible : should be "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart". |
| 5 | - reg: Should contain UART controller registers location and length. |
| 6 | - interrupts: Should contain UART controller interrupts. |
| Stephen Warren | d8f6479 | 2013-11-06 14:00:25 -0700 | [diff] [blame] | 7 | - clocks: Must contain one entry, for the module clock. |
| 8 | See ../clocks/clock-bindings.txt for details. |
| Stephen Warren | 0799958 | 2013-11-07 10:11:27 -0700 | [diff] [blame] | 9 | - resets : Must contain an entry for each entry in reset-names. |
| 10 | See ../reset/reset.txt for details. |
| 11 | - reset-names : Must include the following entries: |
| 12 | - serial |
| Stephen Warren | ed520c9 | 2013-11-11 13:04:19 -0700 | [diff] [blame] | 13 | - dmas : Must contain an entry for each entry in clock-names. |
| 14 | See ../dma/dma.txt for details. |
| 15 | - dma-names : Must include the following entries: |
| 16 | - rx |
| 17 | - tx |

| 19 | Optional properties: |
| 20 | - nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable |
| 21 | only if all 8 lines of UART controller are pinmuxed. |
