| * 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; |
| }; |
| }; |
