* Freescale Low Power SPI (LPSPI) for i.MX
|
|
|
|
Required properties:
|
|
- compatible :
|
|
- "fsl,imx7ulp-spi" for LPSPI compatible with the one integrated on i.MX7ULP soc
|
|
- "fsl,imx8qxp-spi" for LPSPI compatible with the one integrated on i.MX8QXP soc
|
|
- reg : address and length of the lpspi master registers
|
|
- interrupt-parent : core interrupt controller
|
|
- interrupts : lpspi interrupt
|
|
- clocks : lpspi clock specifier
|
|
- spi-slave : spi slave mode support. In slave mode, add this attribute without
|
|
value. In master mode, remove it.
|
|
|
|
Examples:
|
|
|
|
lpspi2: lpspi@40290000 {
|
|
compatible = "fsl,imx7ulp-spi";
|
|
reg = <0x40290000 0x10000>;
|
|
interrupt-parent = <&intc>;
|
|
interrupts = <GIC_SPI 28 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&clks IMX7ULP_CLK_LPSPI2>;
|
|
spi-slave;
|
|
};
