* 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

- reg : address and length of the lpspi master registers

- interrupt-parent : core interrupt controller

- interrupts : lpspi interrupt

- clocks : lpspi clock specifier



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>;

};
