Subject: [PATCH 1/9] arm64: dts: ti: k3-j721e-sk: Add missing uart pinmuxes
Date: Thu, 1 Jun 2023 13:31:43 -0500	[thread overview]
Message-ID: <20230601183151.1000157-2-nm@ti.com> (raw)
In-Reply-To: <20230601183151.1000157-1-nm@ti.com>

Rather than depend on the default pinmuxes, explicitly describe the
pinmux
