-* Freescale LINFlexD UART
-
-The LINFlexD controller implements several LIN protocol versions, as well as
-support for full-duplex UART communication through 8-bit and 9-bit frames.
-
-See chapter 47 ("LINFlexD") in the reference manual[1].
-
-Required properties:
-- compatible :
-  - "fsl,s32v234-linflexuart" for LINFlexD configured in UART mode, which
-    is compatible with the one integrated on S32V234 SoC
-- reg : Address and length of the register set for the device
-- interrupts : Should contain uart interrupt
-
-Example:
-uart0: serial@40053000 {
-	compatible = "fsl,s32v234-linflexuart";
-	reg = <0x0 0x40053000 0x0 0x1000>;
-	interrupts = <0 59 4>;
-};
