OMAP UART controller
|
|
|
|
Required properties:
|
|
- compatible : should be "ti,omap2-uart" for OMAP2 controllers
|
|
- compatible : should be "ti,omap3-uart" for OMAP3 controllers
|
|
- compatible : should be "ti,omap4-uart" for OMAP4 controllers
|
|
- compatible : should be "ti,am4372-uart" for AM437x controllers
|
|
- compatible : should be "ti,am3352-uart" for AM335x controllers
|
|
- compatible : should be "ti,dra742-uart" for DRA7x controllers
|
|
- reg : address and length of the register space
|
|
- interrupts or interrupts-extended : Should contain the uart interrupt
|
|
specifier or both the interrupt
|
|
controller phandle and interrupt
|
|
specifier.
|
|
- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)
|
|
|
|
Optional properties:
|
|
- clock-frequency : frequency of the clock input to the UART
|
|
- dmas : DMA specifier, consisting of a phandle to the DMA controller
|
|
node and a DMA channel number.
|
|
- dma-names : "rx" for receive channel, "tx" for transmit channel.
|
|
|
|
Example:
|
|
|
|
uart4: serial@49042000 {
|
|
compatible = "ti,omap3-uart";
|
|
reg = <0x49042000 0x400>;
|
|
interrupts = <80>;
|
|
dmas = <&sdma 81 &sdma 82>;
|
|
dma-names = "tx", "rx";
|
|
ti,hwmods = "uart4";
|
|
clock-frequency = <48000000>;
|
|
};
