-* 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,imx8qxp-lpi2c" for LPI2C compatible with the one integrated on i.MX8QXP soc
- - "fsl,imx8qm-lpi2c" for LPI2C compatible with the one integrated on i.MX8QM soc
-- reg : address and length of the lpi2c master registers
-- interrupts : lpi2c interrupt
-- clocks : lpi2c clock specifier

-Examples:
-
-lpi2c7: lpi2c7@40a50000 {
- compatible = "fsl,imx7ulp-lpi2c";
