Subject: [PATCH v2 8/8] arm64: dts: apple: t8103: Add UART2
Date: Mon, 25 Oct 2021 23:47:18 +0900	[thread overview]
Message-ID: <20211025144718.157794-9-marcan@marcan.st> (raw)
In-Reply-To: <20211025144718.157794-1-marcan@marcan.st>

This UART is connected to the debug port of the WLAN module. It is
mostly useless, but makes for a good test case for runtime-pm without
having to unbind the console from the main system UART.
