8fc7d03c3f dt-bindings: serial: st,stm32-uart: drop common properties 
The binding references serial and rs485 schemas, so there is no need to
list their properties.  Simplify a bit by removing unneeded entries.

84e85359f4 dt-bindings: drop redundant part of title (end, part three) 
The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full
stop):

  find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
    -not -name 'trivial-devices.yaml' \
    -exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

8f082dcf2c dt-bindings: serial: Change to reference the kernel-defined serial.yaml 
The /schemas/serial.yaml from dt-schema only has the property $nodename,
whereas the kernel-defined /schemas/serial/serial.yaml contains more
useful properties, support for more complex application scenarios.

For example:
1) The property "current-speed" in fsl-lx2160a.dtsi
2) The subnode "bluetooth" in hi3660-hikey960.dts

To use additional properties 'bluetooth' on serial, need replace false with
'type: object' for 'additionalProperties' to make it as a node, else will
run into dtbs_check warnings.

'arch/arm/boot/dts/stm32h750i-art-pi.dt.yaml: serial@40004800:
'bluetooth' does not match any of the regexes: 'pinctrl-[0-9]+'

9ba8377c3a dt-bindings: serial: stm32: update rts-gpios and cts-gpios 
Update rts-gpios and cts-gpios:
- remove max-items as already defined in serial.yaml
- add a note describing rts-gpios and cts-gpios usage with stm32

Document the use of cts-gpios and rts-gpios for flow control in STM32 UART
controller. These properties can be used instead of 'uart-has-rtscts' or
'st,hw-flow-ctrl' (deprecated) for making use of any gpio pins for flow
control instead of dedicated pins.
It should be noted that both cts-gpios/rts-gpios and 'uart-has-rtscts' or
'st,hw-flow-ctrl' (deprecated) properties cannot co-exist in a design.
