| * 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>, /* GPIO3_24 */ |
| <&gpio3 25 0>; /* GPIO3_25 */ |
| }; |
