     * 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. Its number and order need to correspond to the
               value in clock-names.
    - clock-names : Corresponding to per clock and ipg clock in "clocks"
                    respectively. In i.MX7ULP, it only has per clk, so use CLK_DUMMY
                    to fill the "ipg" blank.
    - 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>,
                     <&clks IMX7ULP_CLK_DUMMY>;
            clock-names = "per", "ipg";
            spi-slave;
    };
