Subject: [PATCH 6/9] arm64: dts: ti: k3-j721e-beagleboneai64: Add wakeup_uart pinmux
Date: Thu, 1 Jun 2023 13:31:48 -0500 [thread overview]
Message-ID: <20230601183151.1000157-7-nm@ti.com> (raw)
In-Reply-To: <20230601183151.1000157-1-nm@ti.com>
Define the wakeup uart pin-mux for completeness. This allows the
device tree usage in bootloader and firmwares that can configure the
same appropriately.
