| * 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>; |
