* Freescale MX233/MX28 SSP/SPI
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,<soc>-spi", where soc is "imx23" or "imx28"
|
|
- reg: Offset and length of the register set for the device
|
|
- interrupts: Should contain SSP interrupts (error irq first, dma irq second)
|
|
- fsl,ssp-dma-channel: APBX DMA channel for the SSP
|
|
|
|
Optional properties:
|
|
- clock-frequency : Input clock frequency to the SPI block in Hz.
|
|
Default is 160000000 Hz.
|
|
|
|
Example:
|
|
|
|
ssp0: ssp@80010000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "fsl,imx28-spi";
|
|
reg = <0x80010000 0x2000>;
|
|
interrupts = <96 82>;
|
|
fsl,ssp-dma-channel = <0>;
|
|
};
