[RFC PATCH v1 1/3] dt-bindings: touchscreen: add touchscreen-x/y-plate-ohms property
From: Oleksij Rempel
Date: Mon May 17 2021 - 08:59:33 EST
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
