1* GSL 1680 touchscreen controller
2
3Required properties:
4- compatible : "silead,gsl1680"
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 gsl1680 interrupt
9- power-gpios : Specification for the pin connected to the gsl1680's
10 shutdown input. This needs to be driven high to take the
11 gsl1680 out of its low power state
12- touchscreen-size-x : See touchscreen.txt
13- touchscreen-size-y : See touchscreen.txt
14
15Optional properties:
16- firmware-name : File basename (string) for board specific firmware
17- touchscreen-inverted-x : See touchscreen.txt
18- touchscreen-inverted-y : See touchscreen.txt
19- touchscreen-swapped-x-y : See touchscreen.txt
20- silead,max-fingers : maximum number of fingers the touchscreen can detect
21- vddio-supply : regulator phandle for controller VDDIO
22- avdd-supply : regulator phandle for controller AVDD
