This patch defines common Armada XP pinctrl settings for uart2 and uart3 interfaces (uart0 and uart1 rx/tx do not rely on MPP): uart2: MPP42-43 as default uart3: MPP44-45 as default Suggested-by: Andrew Lunn <redacted> Signed-off-by: Arnaud Ebalard <redacted> --- arch/arm/boot/dts/armada-xp.dtsi | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
