| 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. |
