1 | * Freescale (Enhanced) Configurable Serial Peripheral Interface |
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>; | |
