[ Upstream commit fca053893e8d5be8173c92876c6329cbee78b880 ]
The following build warnings are seen when running:
make dtbs_check DT_SCHEMA_FILES=fsl-imx-uart.yaml
arch/arm64/boot/dts/freescale/imx8mm-venice-gw7903.dtb: serial@30860000: cts-gpios: False schema does not allow [[33, 3, 1]] From schema: Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml arch/arm64/boot/dts/freescale/imx8mm-venice-gw7903.dtb: serial@30860000: rts-gpios: False schema does not allow [[33, 5, 1]] From schema: Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml ...
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.
