* Freescale Low Power Inter IC (LPI2C) for i.MX
Required properties:
- compatible :
- "fsl,imx7ulp-lpi2c" for LPI2C compatible with the one integrated on i.MX7ULP soc
- "fsl,imx8dv-lpi2c" for LPI2C compatible with the one integrated on i.MX8DV soc
- reg : address and length of the lpi2c master registers
- interrupt-parent : core interrupt controller
- interrupts : lpi2c interrupt
- clocks : lpi2c clock specifier
Examples:
lpi2c7: lpi2c7@40A50000 {
compatible = "fsl,imx8dv-lpi2c";
reg = <0x40A50000 0x10000>;
interrupt-parent = <&intc>;
interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX7ULP_CLK_LPI2C7>;
};
