+* 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>;
