Subject: [PATCH 7/7] arm64: dts: apple: t8103: Add UART2
Date: Wed, 6 Oct 2021 00:59:23 +0900 [thread overview]
Message-ID: <20211005155923.173399-8-marcan@marcan.st> (raw)
In-Reply-To: <20211005155923.173399-1-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.
