| * Texas Instruments tsc2004 and tsc2005 touchscreen controllers |
| |
| Required properties: |
| - compatible : "ti,tsc2004" or "ti,tsc2005" |
| - reg : Device address |
| - interrupts : IRQ specifier |
| - spi-max-frequency : Maximum SPI clocking speed of the device |
| (for tsc2005) |
| |
| Optional properties: |
| - vio-supply : Regulator specifier |
| - reset-gpios : GPIO specifier for the controller reset line |
| - ti,x-plate-ohms : integer, resistance of the touchscreen's X plates |
| in ohm (defaults to 280) |
| - ti,esd-recovery-timeout-ms : integer, if the touchscreen does not respond after |
| the configured time (in milli seconds), the driver |
| will reset it. This is disabled by default. |
| - properties defined in touchscreen.txt |
