I am using LCD Touch panel(i.e OSD0700T4751) connected to am437x based custom board. LCD Display was working fine but Touch was not working with sample qt based demo application.
Here is my dts changes related to lcd & touch.
lcd0: display {
compatible = "osddisplays,osd070t1718-19ts", "panel-dpi";
//compatible = "osddisplays,osd0700t4751-19ts ", "panel-dpi";
label = "lcd";
backlight = <&lcd_bl>;

clock-frequency = <30000000>;

hback-porch = <16>;
hsync-len = <30>;
vback-porch = <10>;
vfront-porch = <22>;
vsync-len = <13>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <1>;
};
port {
lcd_in: endpoint {
remote-endpoint = <&dpi_out>;
};
};
};
&i2c1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins_default>;

pinctrl-0 = <&pixcir_ts_pins>;
reg = <0x5c>;
attb-gpio = <&gpio1 3 GPIO_ACTIVE_HIGH>;
/* <TOOO> not sure how this 0x264 is derived

*/
interrupts-extended = <&gpio1 3 IRQ_TYPE_EDGE_FALLING>,

interrupt-names = "tsc", "wakeup";

wakeup-source;

};
};
