3 Required properties:
4  - compatible             : "elan,ektf2127"
5  - reg                    : I2C slave address of the chip (0x40)
6  - interrupt-parent       : a phandle pointing to the interrupt controller
7                             serving the interrupt for this chip
8  - interrupts             : interrupt specification for the ektf2127 interrupt
9  - power-gpios            : GPIO specification for the pin connected to the
10                             ektf2127's wake input. This needs to be driven high
11                             to take ektf2127 out of it's low power state
