Just "see touchscreen.txt" is fine for the description of common properties.

+Optional properties:
+- reset-gpios : reset gpio.
+- touchscreen-swapped-x-y : swap x/y axis coordinates.
+- linux,keycodes : Specifies an array of numeric keycode values to
+ be used for reporting button presses. The array can
+ contain up to 8 entries.
+- goodix,normal-cfg-X : touch device normal config data, this config data is
+ touchpanel manufacturer related. normal-cfg-X, X
+ represent for a panel manufacturer, X is less than 10.
+- vtouch-supply : power supply for the touch device.
