    1 Bindings for EETI touchscreen controller
    2 
    3 Required properties:
    4 - compatible:   should be "eeti,exc3000-i2c"
    5 - reg:          I2C address of the chip. Should be set to <0xa>
    6 - interrupts:   interrupt to which the chip is connected
    7 
    8 Optional properties:
    9 - attn-gpios:   A handle to a GPIO to check whether interrupt is still
   10                 latched. This is necessary for platforms that lack
   11                 support for level-triggered IRQs.
   12 
   13 The following optional properties described in touchscreen.txt are
   14 also supported:
   15 
   16 - touchscreen-inverted-x
   17 - touchscreen-inverted-y
   18 - touchscreen-swapped-x-y
   19 
   20 Example:
   21 
   22 i2c-master {
   23         touchscreen@a {
   24                 compatible = "eeti,exc3000-i2c";
   25                 reg = <0xa>;
   26                 interrupt-parent = <&gpio>;
   27                 interrupts = <123 IRQ_TYPE_EDGE_RISING>;
   28                 attn-gpios = <&gpio 123 GPIO_ACTIVE_HIGH>;
   29         };
   30 };
