Kernel-4.18.0-80.el8_tsc2005

• 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.
