From d4e913bad2b58e8da474c4e7d4ee92afd4e2f03e Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 21 Nov 2022 17:22:59 -0300 Subject: [PATCH] ARM: dts: imx6qdl-gw560x: Remove incorrect 'uart-has-rtscts' [ Upstream commit 9dfbc72256b5de608ad10989bcbafdbbd1ac8d4e ] The following build warning is seen when running: make dtbs_check DT_SCHEMA_FILES=fsl-imx-uart.yaml arch/arm/boot/dts/imx6dl-gw560x.dtb: serial@2020000: rts-gpios: False schema does not allow [[20, 1, 0]] From schema: Documentation/devicetree/bindings/serial/fsl-imx-uart.yaml The imx6qdl-gw560x board does 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.
