-* 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
-
-Example:
-
-&i2c3 {
- tsc2004@48 {
