|  | * 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 */ | 
|  | }; |
