- * 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 */
- };
