New common bindings have been defined by commit b98abe52fa8e: Documentation/devicetree/bindings/input/touchscreen/touchscreen.txt which also defines a helper function to parse the DT. These new parameters allow to specify the fuzz factors (jitter suppression), inversion of x or y axis and swapping of x and y to achieve inversion and rotation so that the touch coordinate axes match the natural orientation of the display panel. Another improvement is to better use the min/max ADC values and scale to the screen size as defined by the DT. This allows to coarsely calibrate the touch to match the LCD to which it is glued on so that the touch can quite precisely be operated before any user-space fine-calibration can be (and needs to be) started. For the adc7846 we fix an issue with the spi module table. Finally we add an iio interface for the AUX and temperature ADC channels of the tsc2007 and also provide the touch screen raw values. This allows to read an optional ambient light sensor installed on the gta04 board and improves calibration and hardware monitoring. H.
