- * Texas Instruments tsc2005 touchscreen controller
- Required properties:
- - compatible : "ti,tsc2005"
- - reg : SPI device address
- - spi-max-frequency : Maximal SPI speed
- - interrupts : IRQ specifier
- - reset-gpios : GPIO specifier
- - vio-supply : Regulator specifier
- Optional properties:
- - 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
- Example:
- &mcspi1 {
- tsc2005@0 {
- compatible = "ti,tsc2005";
- spi-max-frequency = <6000000>;
- reg = <0>;
- vio-supply = <&vio>;
- reset-gpios = <&gpio4 8 GPIO_ACTIVE_HIGH>; /* 104 */
- interrupts-extended = <&gpio4 4 IRQ_TYPE_EDGE_RISING>; /* 100 */
- touchscreen-fuzz-x = <4>;
- touchscreen-fuzz-y = <7>;
- touchscreen-fuzz-pressure = <2>;
- touchscreen-max-x = <4096>;
- touchscreen-max-y = <4096>;
- touchscreen-max-pressure = <2048>;
- ti,x-plate-ohms = <280>;
- ti,esd-recovery-timeout-ms = <8000>;
- };
- }
