+* 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
+
+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 = 600;
+ reg = 0;
+
+ reset-gpios = gpio4 8 GPIO_ACTIVE_HIGH; /* 104 */
+ interrupts-extended = gpio4 4 IRQ_TYPE_NONE; /* 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;
+ };
+}
