+* Pixcir I2C touchscreen controllers
+
+Required properties:
+- compatible: must be "pixcir,pixcir_ts" or "pixcir,pixcir_tangoc"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+- attb-gpio: GPIO connected to the ATTB line of the chip
+- x-size: horizontal resolution of touchscreen
+- y-size: vertical resolution of touchscreen

There is a patch by Sebastian Reichel trying to unify touchscreen OF
properties, I think it would be nice if we used the same properties
here.

OK, I'll update this patch.

cheers,
