BeagleBone 5 wire resistive touchscreen

Hi,

I'm running kernel v3.8 on beaglebone and I want to attach 5 wire resistive touch screen. This is associated section in my dts file:

tscadc {
compatible = "ti,ti-tscadc";
reg = <0x44e0d000 0x1000>;

interrupt-parent = <&intc>;
interrupts = <16>;
ti,hwmods = "adc_tsc";
status = "okay";

tsc {
ti,wires = <5>;
ti,x-plate-resistance = <200>;
ti,steps-to-configure = <5>;
ti,wire-config = <0x00 0x11 0x22 0x33>;
};

adc {
ti,adc-channels = <3>;
};
};

According to wire-config, which is default I think, I'm connecting: AN0 -> Upper Left; AN1 -> Upper Right; AN2 -> Lower Left; AN3 -> Lower Right. The wiper is connected on AN4.

I use TI's evtest utility to test the touchscreen and I can notice continuous data (with pretty much same values) without pressing the screen. No difference if I press the screen. The same touch screen on the same board works great with 3.2 kernel version (again i'm using evtest till callibration).

I noticed that driver is not the same since now supports wire order configuration, but any combination in wire-config doesn't work for me. Am I missing something?

Any help would be appreciated.

Regards,
