- reg : Address and length of the register set for the device
- 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.
Optional properties:
- dmas: A list of two dma specifiers, one for each entry in dma-names.
