The imx8m Venice Gateworks boards do not expose the UART RTS and CTS as native UART pins, so 'uart-has-rtscts' should not be used. Using 'uart-has-rtscts' with 'rts-gpios' is an invalid combination detected by serial.yaml. Fix the problem by removing the incorrect 'uart-has-rtscts' property. Fixes: 27c8f4ccc1b9 ("arm64: dts: imx8mm-venice-gw72xx-0x: add dt overlays for serial modes") Fixes: d9a9a7cf32c9 ("arm64: dts: imx8m{m,n}-venice-*: add missing uart-has-rtscts property to UARTs") Fixes: 870f645b396b ("arm64: dts: imx8mp-venice-gw74xx: add WiFi/BT module support") Signed-off-by: Fabio Estevam <festevam@xxxxxxx> --- .../boot/dts/freescale/imx8mm-venice-gw72xx-0x-rs232-rts.dtso | 1 - .../boot/dts/freescale/imx8mm-venice-gw73xx-0x-rs232-rts.dtso | 1 - arch/arm64/boot/dts/freescale/imx8mm-venice-gw73xx.dtsi | 1 - arch/arm64/boot/dts/freescale/imx8mm-venice-gw7901.dts | 3 --- arch/arm64/boot/dts/freescale/imx8mm-venice-gw7902.dts | 3 --- arch/arm64/boot/dts/freescale/imx8mm-venice-gw7903.dts | 1 - arch/arm64/boot/dts/freescale/imx8mn-venice-gw7902.dts | 1 - arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx.dts | 1 - 8 files changed, 12 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-rs232-rts.dtso b/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-rs232-rts.dtso index 3ea73a6886ff..f6ad1a4b8b66 100644 --- a/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-rs232-rts.dtso +++ b/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-rs232-rts.dtso @@ -33,7 +33,6 @@ pinctrl-0 = <&pinctrl_uart2>;
