| * Elan eKTF2127 I2C touchscreen controller | |
| Required properties: | |
| - compatible : "elan,ektf2127" | |
| - reg : I2C slave address of the chip (0x40) | |
| - interrupt-parent : a phandle pointing to the interrupt controller | |
| serving the interrupt for this chip | |
| - interrupts : interrupt specification for the ektf2127 interrupt | |
| - power-gpios : GPIO specification for the pin connected to the | |
| ektf2127's wake input. This needs to be driven high | |
| to take ektf2127 out of it's low power state | |
| For additional optional properties see: touchscreen.txt | |
| Example: | |
| i2c@00000000 { | |
| ektf2127: touchscreen@15 { | |
| compatible = "elan,ektf2127"; | |
| reg = <0x15>; | |
| interrupt-parent = <&pio>; | |
| interrupts = <6 11 IRQ_TYPE_EDGE_FALLING> | |
| power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; | |
| touchscreen-inverted-x; | |
| touchscreen-swapped-x-y; | |
| }; | |
| }; |
