Convert binding doc ads7846.txt to yaml format.
Additional change:
- add ref to touchscreen.yaml and spi-peripheral-props.yaml.
- use common node name touchscreen.

Fix below warning: arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dtb: touchscreen@0:
  ti,x-min: b'\x00}' is not of type 'object', 'array', 'boolean', 'null'

There are warning:
Documentation/devicetree/bindings/input/touchscreen/ti,ads7843.yaml: properties:ti,x-plate-ohms: '$ref' should not be valid under {'const': '$ref'}
  hint: Standard unit suffix properties don't need a type $ref

I don't know how to fix it. ti,x-plate-ohms is 16bit, but default it is
uint32

It's going to have to be a special case in dtschema. I'll work on a fix.

Should be fixed now in dtschema main branch.

Strange, dt_binding_check can pass. but

 make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 CHECK_DTBS=y imx8mm-var-som-symphony.dtb
  UPD     include/config/kernel.release
  DTC [C] arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dtb
arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dtb: touchscreen@0: ti,x-plate-ohms: 180 is not of type 'array'
        from schema $id: http://devicetree.org/schemas/property-units.yaml#

anything wrong?

Now fixed.

Yes, thanks.

A new error in dt_binding_check

Documentation/devicetree/bindings/input/touchscreen/ti,tsc2005.yaml: ti,x-plate-ohms: missing type definition
