- interrupts : Should contain uart interrupt

- clocks : phandle + clock specifier pairs, one for each entry in clock-names

- clock-names : should contain: "ipg" - the uart clock

- clock-names : For vf610/ls1021a/imx7ulp, "ipg" clock is for uart bus/baud

  clock. For imx8qxp lpuart, "ipg" clock is bus clock that is used to access

  lpuart controller registers, it also requires "baud" clock for module to

  receive/transmit data.
