1* Elan eKTF2127 I2C touchscreen controller
2
3Required 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

24		touchscreen-inverted-x;
25		touchscreen-swapped-x-y;
