Subject: [PATCH 1/5] riscv: dts: spacemit: set console baud rate on K3 Pico-ITX board
Date: Sat, 20 Jun 2026 08:22:02 +0200	[thread overview]
Message-ID: <20260620062238.3199108-2-aurelien@aurel32.net> (raw)
In-Reply-To: <20260620062238.3199108-1-aurelien@aurel32.net>

Because the default console's baud rate is not set, defconfig kernels do
not have any serial output on this platform. Set the baud rate to
115200, matching what is used by U-Boot etc on this platform.

Fixes: 7a6131804986 ("riscv: dts: spacemit: add K3 Pico-ITX board support")
