Subject: [PATCH] dt-bindings: serial: renesas,scif: Fix 4th IRQ for 4-IRQ SCIFs
Date: Fri, 17 Mar 2023 10:46:57 +0100 [thread overview]
Message-ID: <719d1582e0ebbe3d674e3a48fc26295e1475a4c3.1679046394.git.geert+renesas@glider.be> (raw)
The fourth interrupt on SCIF variants with four interrupts (RZ/A1) is
the Break interrupt, not the Transmit End interrupt (like on SCI(g)).
Update the description and interrupt name to fix this.
Fixes: 384d00fae8e51f8f ("dt-bindings: serial: sh-sci: Convert to json-schema")
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

arch/arm/boot/dts/r7s72100.dtsi does not need an update, as its SCIF
device nodes do not contain interupt-names properties.
drivers/tty/serial/sh-sci.c does not need an update, as the driver
does not use named interrupts, and always used the correct handler.
