Kernel-4.18.0-80.el8_spi-fsl-lpspi

  • 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>;
};
