+* TSC2005 Touchscreen
+
+Required properties:
+ - compatible : "ti,tsc2005"
+ - reg : SPI device address
+ - spi-max-frequency : Maximal SPI speed
+ - interrupts : IRQ specifier
+ - reset-gpio : GPIO specifier
+
+Optional properties:
+ - ti,fuzz-x : integer, X noise value of the touchscreen
+ (defaults to 4)
+ - ti,fuzz-y : integer, Y noise value of the touchscreen
+ (defaults to 8)
+ - ti,fuzz-pressure : integer, pressure noise value of the touchscreen
+ (defaults to 2)
+ - ti,max-x : integer, maximum reported x value
+ (defaults to 4096)
+ - ti,max-y : integer, maximum reported y value
+ (defaults to 4096)
+ - ti,max-pressure : integer, maximum reported pressure
+ (defaults to 4096)
+ - ti,x-plate-resistance : 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.
+
+Example:
+
+&mcspi1 {
+ tsc2005@0 {
+ compatible = "ti,tsc2005";
+ spi-max-frequency = <6000000>;
+ reg = <0>;
+ reset-gpio = <&gpio4 8 GPIO_ACTIVE_HIGH>; /* 104 */
+ interrupt-parent = <&gpio4>;
+ interrupts = <4 IRQ_TYPE_NONE>; /* gpio line 100 */
+
+ ti,fuzz-x = <4>;
+ ti,fuzz-y = <7>;
+ ti,fuzz-pressure = <2>;
+ ti,max-x = <4096>;
+ ti,max-y = <4096>;
+ ti,max-pressure = <2048>;
+ ti,x-plate-resistance = <280>;
+ ti,esd-recovery-timeout-ms = <8000>;
+ };
+}
