- 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 Signed-off-by: Gary Bisson <gary.bisson@boundarydevices.com> --- Changes v1->v2: - renamed nodes as suggested by Neil Cc: Rob Herring <robh+dt@kernel.org> Cc: Neil Armstrong <narmstrong@baylibre.com> Cc: Kevin Hilman <khilman@baylibre.com> Cc: Jerome Brunet <jbrunet@baylibre.com> Cc: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Cc: devicetree@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org --- .../boot/dts/amlogic/meson-g12-common.dtsi | 27 +++++++++++++++++++ 1 file changed, 27 insertions(+)
