Te calculate the pressure on a restrictive touchscreen we need need to know resistance at least of X plate. Some calculations need to use both X and Y values. So, add generic properties which can be used by all drivers Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> --- .../devicetree/bindings/input/touchscreen/touchscreen.yaml | 6 ++++++ 1 file changed, 6 insertions(+)
