Thx to this post, I managed to make the continuous mode working.

Robert: the correct overlay should be :
tscadc@44e0d000 {
compatible = "ti,am3359-tscadc";
reg = <0x44e0d000 0x1000>;
interrupt-parent = <0x1>;
interrupts = <0x10>;
ti,hwmods = "adc_tsc";
status = "okay";
linux,phandle = <0xc5>;
phandle = <0xc5>;
tsc {
compatible = "ti,am3359-tsc";
};
adc {
#io-channel-cells = <0x1>;
compatible = "ti,am3359-adc";
linux,phandle = <0xc6>;
phandle = <0xc6>;
ti,adc-channels = <0 1 2 3 4 5 6 7>;
};
};
