Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

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.
|
|
- clocks: Must contain one entry, for the module clock.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- resets : Must contain an entry for each entry in reset-names.
|
|
See ../reset/reset.txt for details.
|
|
- reset-names : Must include the following entries:
|
|
- serial
|
|
- dmas : Must contain an entry for each entry in dma-names.
|
|
See ../dma/dma.txt for details.
|
|
- dma-names : Must include the following entries:
|
|
- rx
|
|
- tx
|
|
|
|
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,enable-modem-interrupt;
|
|
clocks = <&tegra_car 6>;
|
|
resets = <&tegra_car 6>;
|
|
reset-names = "serial";
|
|
dmas = <&apbdma 8>, <&apbdma 8>;
|
|
dma-names = "rx", "tx";
|
|
};
