* Freescale (Enhanced) Configurable Serial Peripheral Interface
(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 */
};
