|
(CSPI/eCSPI) for i.MX
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,<soc>-cspi" or "fsl,<soc>-ecspi"
|
|
- reg : Offset and length of the register set for the device
|
|
- interrupts : Should contain CSPI/eCSPI interrupt
|
|
- fsl,spi-num-chipselects : Contains the number of the chipselect
|
|
- cs-gpios : Specifies the gpio pins to be used for chipselects.
|
|
|
|
Example:
|
|
|
|
ecspi@70010000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "fsl,imx51-ecspi";
|
|
reg = <0x70010000 0x4000>;
|
|
interrupts = <36>;
|
|
fsl,spi-num-chipselects = <2>;
|
|
cs-gpios = <&gpio3 24 0>, /* GPIO4_24 */
|
|
<&gpio3 25 0>; /* GPIO4_25 */
|
|
};
