| 2 | (CSPI/eCSPI) for i.MX |
| 3 | |
| 4 | Required properties: |
| 5 | - compatible : Should be "fsl,<soc>-cspi" or "fsl,<soc>-ecspi" |
| 6 | - reg : Offset and length of the register set for the device |
| 7 | - interrupts : Should contain CSPI/eCSPI interrupt |
| 8 | - fsl,spi-num-chipselects : Contains the number of the chipselect |
| 9 | - cs-gpios : Specifies the gpio pins to be used for chipselects. |
| 10 | |
| 11 | Example: |
| 12 | |
| 13 | ecspi@70010000 { |
| 14 | #address-cells = <1>; |
| 15 | #size-cells = <0>; |
| 16 | compatible = "fsl,imx51-ecspi"; |
| 17 | reg = <0x70010000 0x4000>; |
| 18 | interrupts = <36>; |
| 19 | fsl,spi-num-chipselects = <2>; |
| 20 | cs-gpios = <&gpio3 24 0>, /* GPIO4_24 */ |
| 21 | <&gpio3 25 0>; /* GPIO4_25 */ |
| 22 | }; |
