Avoid this and enforce reliable numbering by adding serialX aliases for: UART1 - on Wifi/BT connector UART2 - on Pi-2 connector UART3 - on Euler connector UART4 - on Euler connector Signed-off-by: Andreas Färber --- arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts b/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts index c680ed385da3..db6c0f36999e 100644 --- a/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts +++ b/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts @@ -52,6 +52,10 @@ aliases { serial0 = &uart0; + serial1 = &uart1; + serial2 = &uart2; + serial3 = &uart3; + serial4 = &uart4; }; chosen { -- 2.10.2
