From: Chester Lin
Date: Wed Sep 08 2021 - 02:46:30 EST


Convert the FSL LINFlexD UART binding to json-schema.

Changes in v2:
- Drop the specific description "S32V234 SoC".
- Fill my name in the maintainer field. I tried to contact the authors
of fsl,s32-linflexuart.txt but got no response.

-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>;
