* Rohm BU21029 Touch Screen Controller
Required properties:
- compatible : must be "rohm,bu21029"
- reg : i2c device address of the chip (0x40 or 0x41)
- interrupt-parent : the phandle for the gpio controller
- interrupts : (gpio) interrupt to which the chip is connected
- rohm,x-plate-ohms : x-plate resistance in Ohm
Optional properties:
- reset-gpios : gpio pin to reset the chip (active low)
- touchscreen-size-x : horizontal resolution of touchscreen (in pixels)
- touchscreen-size-y : vertical resolution of touchscreen (in pixels)
- touchscreen-max-pressure: maximum pressure value
- vdd-supply : power supply for the controller
Example:
&i2c1 {
/* ... */
bu21029: bu21029@40 {
compatible = "rohm,bu21029";
reg = <0x40>;
interrupt-parent = <&gpio1>;
interrupts = <4 IRQ_TYPE_EDGE_FALLING>;
reset-gpios = <&gpio6 16 GPIO_ACTIVE_LOW>;
rohm,x-plate-ohms = <600>;
touchscreen-size-x = <800>;

Bindings for EETI touchscreen controller
Required properties:
- compatible: should be "eeti,exc3000-i2c"
- reg: I2C address of the chip. Should be set to <0xa>
- interrupts: interrupt to which the chip is connected
Optional properties:
- attn-gpios: A handle to a GPIO to check whether interrupt is still
latched. This is necessary for platforms that lack
support for level-triggered IRQs.
The following optional properties described in touchscreen.txt are
also supported:
- touchscreen-inverted-x
- touchscreen-inverted-y
- touchscreen-swapped-x-y
Example:
i2c-master {
touchscreen@a {
compatible = "eeti,exc3000-i2c";
reg = <0xa>;
interrupt-parent = <&gpio>;
interrupts = <123 IRQ_TYPE_EDGE_RISING>;
attn-gpios = <&gpio 123 GPIO_ACTIVE_HIGH>;
