1 * Texas Instruments tsc2007 touchscreen controller
4 - compatible: must be "ti,tsc2007".
5 - reg: I2C address of the chip.
6 - ti,x-plate-ohms: X-plate resistance in ohms.
9 - gpios: the interrupt gpio the chip is connected to (trough 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.
