1 * Texas Instruments tsc2005 touchscreen controller
2
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
9  - vio-supply                 : Regulator 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.
