Be consistent with the name: LINFlexD?
+ +The LINFlexD controller implements several LIN protocol versions, as well as +support for full-duplex UART communication through 8-bit and 9-bit frames. The +Linflex UART driver enables operation only in UART mode.
What the driver supports or not is independent of the binding.
+
+See chapter 47 ("LINFlexD") in the reference manual[1].
+
+Required properties:
+- compatible :
+ - "fsl,s32-linflexuart" for linflex configured in uart mode whichLINFlexD?
+ is compatible with the one integrated on S32V234 SoC
Compatibles should be SoC specific. Is 's32' specific enough to account for any differences or future bugs found?
+- reg : Address and length of the register set for the device
+- interrupts : Should contain uart interrupt
+
+Example:
+uart0:serial@40053000 {space ^
+ compatible = "fsl,s32-linflexuart"; + reg = <0x0 0x40053000 0x0 0x1000>; + interrupts = <0 59 4>; + status = "disabled";
Don't show status in examples.
