Move all bindings in bindings/tty/serial into bindings/serial so we only have one place dir with serial/uart related bindings in it. Signed-off-by: Kumar Gala <galak@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* Freescale MXS Application UART (AUART)
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,<soc>-auart". The supported SoCs include
|
|
imx23 and imx28.
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should contain the auart interrupt numbers
|
|
- dmas: DMA specifier, consisting of a phandle to DMA controller node
|
|
and AUART DMA channel ID.
|
|
Refer to dma.txt and fsl-mxs-dma.txt for details.
|
|
- dma-names: "rx" for RX channel, "tx" for TX channel.
|
|
|
|
Optional properties:
|
|
- fsl,uart-has-rtscts : Indicate the UART has RTS and CTS lines,
|
|
it also means you enable the DMA support for this UART.
|
|
|
|
Example:
|
|
auart0: serial@8006a000 {
|
|
compatible = "fsl,imx28-auart", "fsl,imx23-auart";
|
|
reg = <0x8006a000 0x2000>;
|
|
interrupts = <112>;
|
|
dmas = <&dma_apbx 8>, <&dma_apbx 9>;
|
|
dma-names = "rx", "tx";
|
|
};
|
|
|
|
Note: Each auart port should have an alias correctly numbered in "aliases"
|
|
node.
|
|
|
|
Example:
|
|
|
|
aliases {
|
|
serial0 = &auart0;
|
|
serial1 = &auart1;
|
|
serial2 = &auart2;
|
|
serial3 = &auart3;
|
|
serial4 = &auart4;
|
|
};
