[PATCH v4 1/5] dt-bindings: touchscreen: convert bu21013 bindings to json schema

[PATCH v4 1/5] dt-bindings: touchscreen: convert bu21013 bindings to json schema

[Dario Binacchi]

Convert Rohm BU21013 I2C touchscreen controller device tree binding to
json-schema.

Additional changes:
- Replace <supply_name>-supply with avdd-supply to match example and
  existing DTS.
- Add reset-gpios in the example because it is required.

Changes in v4:
- Drop description from reset-gpios
- Re-work description of avdd-supply
- Rename the file to rohm,bu21013.yaml
- Add Reviewed-by tag of Krzysztof Kozlowski

[PATCH v4 5/5] dt-bindings: touchscreen: remove touchscreen.txt

[Dario Binacchi]

With commit 1d6204e2f51f ("dt-bindings: touchscreen: Add touchscreen
schema") touchscreen.txt is no longer needed, and since no other file
refers to it, it can be safely removed.

It should be a child node.

Should I add the touchscreen node to
Documentation/devicetree/bindings/arm/bcm/raspberrypi,bcm2835-firmware.yaml
and remove Documentation/devicetree/bindings/input/touchscreen/raspberrypi,firmware-ts.yaml
from this patch?

Thanks and regards,
