1* Texas Instruments tsc2007 touchscreen controller
2
3Required properties:
4- compatible: must be "ti,tsc2007".
5- reg: I2C address of the chip.
6- ti,x-plate-ohms: X-plate resistance in ohms.
7
8Optional properties:
9- gpios: the interrupt gpio the chip is connected to (through the penirq pin).
10  The penirq pin goes to low when the panel is touched.
11  (see GPIO binding[1] for more details).
12- interrupts: (gpio) interrupt to which the chip is connected
13  (see interrupt binding[0]).
14- ti,max-rt: maximum pressure.
15- ti,fuzzx: specifies the absolute input fuzz x value.
16  If set, it will permit noise in the data up to +- the value given to the fuzz
17  parameter, that is used to filter noise from the event stream.
18- ti,fuzzy: specifies the absolute input fuzz y value.
19- ti,fuzzz: specifies the absolute input fuzz z value.
20- ti,poll-period: how much time to wait (in milliseconds) before reading again the
21  values from the tsc2007.
