[ 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
