Subject: [PATCH 3/3] arm64: dts: meson-g12-common: add uart_ao_b pins muxing
Date: Mon, 3 Jan 2022 16:46:16 +0100 [thread overview]
Message-ID: <20220103154616.308376-4-gary.bisson@boundarydevices.com> (raw)
In-Reply-To: <20220103154616.308376-1-gary.bisson@boundarydevices.com>
- RX/TX signals can be mapped on 2 different pairs of pins so supporting
both options
- RTS/CTS signals however only have 1 option available
