tsc2007.txt (1285B)

      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 (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.
