Kernel-3.10.0-957.el7_nvidia,tegra20-hsuart

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”;
};
