The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.

For pressure calculation based on plates resistance we need some additional properties: - z1 and z2 channels with additional measurements between plates - actual resistance of the touchscreen. Currently we use only X-resistance. Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> --- .../bindings/input/touchscreen/resistive-adc-touch.yaml | 9 +++++++++ 1 file changed, 9 insertions(+)
