| NVIDIA Tegra20/Tegra30 high speed (DMA based) UART controller driver. |
| |
| Required properties: |
| - compatible : should be "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart". |
| - reg: Should contain UART controller registers location and length. |
| - interrupts: Should contain UART controller interrupts. |
| - nvidia,dma-request-selector : The Tegra DMA controller's phandle and |
| request selector for this UART controller. |
| |
| Optional properties: |
| - nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable |
| only if all 8 lines of UART controller are pinmuxed. |
| |
| Example: |
| |
| serial@70006000 { |
| compatible = "nvidia,tegra30-hsuart", "nvidia,tegra20-hsuart"; |
| reg = <0x70006000 0x40>; |
| reg-shift = <2>; |
| interrupts = <0 36 0x04>; |
| nvidia,dma-request-selector = <&apbdma 8>; |
| nvidia,enable-modem-interrupt; |
| status = "disabled"; |
| }; |
