* Freescale low power universal asynchronous receiver/transmitter (lpuart)
|
|
|
|
Required properties:
|
|
- compatible :
|
|
- "fsl,vf610-lpuart" for lpuart compatible with the one integrated
|
|
on Vybrid vf610 SoC with 8-bit register organization
|
|
- "fsl,ls1021a-lpuart" for lpuart compatible with the one integrated
|
|
on LS1021A SoC with 32-bit big-endian register organization
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should contain uart interrupt
|
|
- clocks : phandle + clock specifier pairs, one for each entry in clock-names
|
|
- clock-names : should contain: "ipg" - the uart clock
|
|
|
|
Optional properties:
|
|
- dmas: A list of two dma specifiers, one for each entry in dma-names.
|
|
- dma-names: should contain "tx" and "rx".
|
|
|
|
Note: Optional properties for DMA support. Write them both or both not.
|
|
|
|
Example:
|
|
|
|
uart0: serial@40027000 {
|
|
compatible = "fsl,vf610-lpuart";
|
|
reg = <0x40027000 0x1000>;
|
|
interrupts = <0 61 0x00>;
|
|
clocks = <&clks VF610_CLK_UART0>;
|
|
clock-names = "ipg";
|
|
dmas = <&edma0 0 2>,
|
|
<&edma0 0 3>;
|
|
dma-names = "rx","tx";
|
|
};
