ChangeLog v6->v7:
- One small whitespace cleanup.
- The properties specific to that driver are now prefixed with "ti,".
- The ti,fuzzy property has now better documentation.

+* Texas Instruments tsc2007 touchscreen controller
+
+Required properties:
+- compatible: must be "ti,tsc2007".
+- reg: I2C address of the chip.
+- ti,x-plate-ohms: X-plate resistance in ohms.
+
+Optional properties:
+- gpios: the interrupt gpio the chip is connected to (trough the penirq pin)
+  (see GPIO binding[2] for more details).

Hmmm, why is this needed? Is the line used for anything other than
finding the irq number? If it is just an interrupt then an interrupts
property is all that should be specified.

It's also the pendown detect GPIO. It asserts an interrupt when first
activated and is then polled in the driver until it goes inactive again.
