Subject: [PATCH v3 11/11] arm64: dts: apple: t8103: Add UART2
Date: Wed, 24 Nov 2021 16:46:25 +0900	[thread overview]
Message-ID: <20211124074625.182815-12-marcan@marcan.st> (raw)
In-Reply-To: <20211124073419.181799-1-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.
