1* Elan eKTF2127 I2C touchscreen controller 2 3Required properties: 4 - compatible : "elan,ektf2127" or "elan,ektf2132" 5 - reg : I2C slave address of the chip (0x40) 6 - interrupts : interrupt specification for the ektf2127 interrupt 7 - power-gpios : GPIO specification for the pin connected to the 8 ektf2127's wake input. This needs to be driven high 9 to take ektf2127 out of it's low power state 10 11For additional optional properties see: touchscreen.txt 12 13Example: 14 15i2c@00000000 { 16 ektf2127: touchscreen@15 { 17 compatible = "elan,ektf2127"; 18 reg = <0x15>; 19 interrupt-parent = <&pio>; 20 interrupts = <6 11 IRQ_TYPE_EDGE_FALLING> 21 power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; 22 touchscreen-inverted-x; 23 touchscreen-swapped-x-y; 24 }; 25}; 26
