Subject: [PATCH] arm64: dts: renesas: r8a779g0: Fix HSCIF0 interrupt number
Date: Thu, 25 Aug 2022 11:24:47 +0200	[thread overview]
Message-ID: <751dcef40d4534e856ed49b1d5b3a3e8d365ec42.1661419377.git.geert+renesas@glider.be> (raw)

The interrupt number for the HSCIF0 serial port, which serves as the
serial console on the White Hawk board, is incorrect, causing userspace
to hang immediately as soon as it tries to print something.
Kernel output is unaffected, as it is printed using polling.

Fixes: 987da486d84a5643 ("arm64: dts: renesas: Add Renesas R8A779G0 SoC support")
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
