   3 Required properties:
   4  - compatible                 : "ti,tsc2005"
   5  - reg                        : SPI device address
   6  - spi-max-frequency          : Maximal SPI speed
   7  - interrupts                 : IRQ specifier
   8  - reset-gpios                : GPIO specifier

  10
  11 Optional properties:
  12  - ti,x-plate-ohms            : integer, resistance of the touchscreen's X plates
  13                                 in ohm (defaults to 280)
  14  - ti,esd-recovery-timeout-ms : integer, if the touchscreen does not respond after
  15                                 the configured time (in milli seconds), the driver
  16                                 will reset it. This is disabled by default.
