Kernel-3.10.0-957.el7_fsl-imx-cspi

  • Freescale (Enhanced) Configurable Serial Peripheral Interface
    (CSPI/eCSPI) for i.MX

Required properties:

  • compatible : Should be “fsl,-cspi” or “fsl,-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>, /* GPIO3_24 /
<&gpio3 25 0>; /
GPIO3_25 */
};
