The S6SY761 touchscreen is a capicitive multi-touch controller for mobile use. It's connected with i2c at the address 0x48. This commit provides a basic version of the driver which can handle only initialization, touch events and power states. The controller is controlled by a firmware which, in the version I currently have, doesn't provide all the possible functionalities mentioned in the datasheet.

* Samsung S6SY761 touchscreen controller
|
|
|
|
Required properties:
|
|
- compatible : must be "samsung,s6sy761"
|
|
- reg : I2C slave address, (e.g. 0x48)
|
|
- interrupt-parent : the phandle to the interrupt controller which provides
|
|
the interrupt
|
|
- interrupts : interrupt specification
|
|
- avdd-supply : analogic power supply
|
|
- vdd-supply : power supply
|
|
|
|
Optional properties:
|
|
- touchscreen-size-x : see touchscreen.txt. This property is embedded in the
|
|
device. If defined it forces a different x resolution.
|
|
- touchscreen-size-y : see touchscreen.txt. This property is embedded in the
|
|
device. If defined it forces a different y resolution.
|
|
|
|
Example:
|
|
|
|
i2c@00000000 {
|
|
|
|
/* ... */
|
|
|
|
touchscreen@48 {
|
|
compatible = "samsung,s6sy761";
|
|
reg = <0x48>;
|
|
interrupt-parent = <&gpa1>;
|
|
interrupts = <1 IRQ_TYPE_NONE>;
|
|
avdd-supply = <&ldo30_reg>;
|
|
vdd-supply = <&ldo31_reg>;
|
|
touchscreen-size-x = <4096>;
