-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 (through the penirq pin).
-  The penirq pin goes to low when the panel is touched.
-  (see GPIO binding[1] for more details).
-- interrupts: (gpio) interrupt to which the chip is connected
-  (see interrupt binding[0]).
-- ti,max-rt: maximum pressure.
-- ti,fuzzx: specifies the absolute input fuzz x value.
-  If set, it will permit noise in the data up to +- the value given to the fuzz
-  parameter, that is used to filter noise from the event stream.
-- ti,fuzzy: specifies the absolute input fuzz y value.
-- ti,fuzzz: specifies the absolute input fuzz z value.
-- ti,poll-period: how much time to wait (in milliseconds) before reading again the
-  values from the tsc2007.
