* Parade pt touch controller
|
||
|
|
|
||
|
|
Please add this description here: The Parade Touch controller is connected to the
|
||
|
|
host processor via I2C. The controller generates interrupts when the user touches
|
||
|
|
the panel. The host controller is expected to read the touch coordinates over I2C and
|
||
|
|
pass the coordinates to the rest of the system.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be "parade,pt_i2c_adapter"
|
||
|
|
- reg : i2c slave address of the device.
|
||
|
|
- vdd-supply : digital voltage power supply needed to power device.
|
||
|
|
- avdd-supply : analog voltage power supply needed to power device.
|
||
|
|
- novatek,reset-gpio : reset gpio.
|
||
|
|
- novatek,irq-gpio : irq gpio.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
&i2c_1 {
|
||
|
|
status = "ok";
|
||
|
|
|
||
|
|
/* Parade device tree node */
|
||
|
|
tsc@24 {
|
||
|
|
compatible = "parade,pt_i2c_adapter";
|
||
|
|
reg = <0x24>;
|
||
|
|
status = "ok";
|
||
|
|
|
||
|
|
vdd-supply = <&L29A>;
|
||
|
|
vcc_i2c-supply = <&L21A>;
|

|
|
|
||
|
|
parade,core {
|
||
|
|
parade,rst_gpio = <&tlmm 71 0x00>;
|

parade,irq_gpio = <&tlmm 80 0x2008>;
