Subject: [PATCH 2/2] arm64: dts: ti: k3-am64: Use phandle to stdout UART node
Date: Thu, 1 Jun 2023 13:49:33 -0500 [thread overview]
Message-ID: <20230601184933.358731-2-afd@ti.com> (raw)
In-Reply-To: <20230601184933.358731-1-afd@ti.com>
Using a phandle makes it clear which UART we are choosing without needing
to resolve through an alias first.
Especially useful for boards like the TI J721s2-EVM where the alias is
"serial2" but it actually resolves to the 8th UART instance(main_uart8).
