1 * GSL 1680 touchscreen controller
4 - compatible : Must be one of the following, depending on the model:
10 - reg : I2C slave address of the chip (0x40)
11 - interrupt-parent : a phandle pointing to the interrupt controller
12 serving the interrupt for this chip
13 - interrupts : interrupt specification for the gsl1680 interrupt
14 - power-gpios : Specification for the pin connected to the gsl1680's
15 shutdown input. This needs to be driven high to take the
16 gsl1680 out of its low power state
17 - touchscreen-size-x : See touchscreen.txt
18 - touchscreen-size-y : See touchscreen.txt
21 - firmware-name : File basename (string) for board specific firmware
22 - touchscreen-inverted-x : See touchscreen.txt
23 - touchscreen-inverted-y : See touchscreen.txt
24 - touchscreen-swapped-x-y : See touchscreen.txt
25 - silead,max-fingers : maximum number of fingers the touchscreen can detect
26 - vddio-supply : regulator phandle for controller VDDIO
27 - avdd-supply : regulator phandle for controller AVDD
