1* Samsung S6SY761 touchscreen controller
2
3Required properties:
4- compatible : must be "samsung,s6sy761"
5- reg : I2C slave address, (e.g. 0x48)
6- interrupt-parent : the phandle to the interrupt controller which provides
7 the interrupt
8- interrupts : interrupt specification
9- avdd-supply : analogic power supply
10- vdd-supply : power supply
11
12Optional properties:
13- touchscreen-size-x : see touchscreen.txt. This property is embedded in the
14 device. If defined it forces a different x resolution.
15- touchscreen-size-y : see touchscreen.txt. This property is embedded in the
16 device. If defined it forces a different y resolution.
