* 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>;
};
