Changes V6: * iio patch (no changes elsewhere) - tsc2007_iio: fix a missing return 0 for non-iio case (found by kbuid test robot) - tsc2007_core: group error return paths so that tsc2007_iio_unconfigure is called at only one place - tsc2007_iio: fix copyright (this file is 100% original work) 2016-10-25 21:26:46: Changes V5: * ads7846: remove an empty line (suggested by Andrew F. Davis <afd@xxxxxx>) * ads7846: remove MODULE_ALIAS for SPI (suggested by Andrew F. Davis <afd@xxxxxx>) * tsc2007: fix a bug from swapping patch 3/n and patch 4/n (found by kbuid test robot) * refactored tsc2007 into tsc2007_core and tsc2007_iio (asked for by Jonathan Cameron <jic23@xxxxxxxxxx>) 2016-10-17 16:00:02: Changes V4: * fix a merge/squash issue resulting in a non-bisectable patch set (suggested by kbuid test robot) * remove some unnecessary #include (suggested by Jonathan Cameron <jic23@xxxxxxxxxx>) * make the iio extension depend on CONFIG_IIO rather than selecting it (suggested by Jonathan Cameron <jic23@xxxxxxxxxx>) * swapped patch 3/n and patch 4/n to remove internal dependency 2016-09-23 14:41:23: Changes V3: * fix an issue with swapping * remove hard clipping to min/max rectangle - some systems expect to handle negative coordinates * make use of commit ed7c9870c9bc ("Input: of_touchscreen - add support for inverted / swapped axes") 2015-11-13 21:36:07: Changes V2: * add a patch to make drivers still recognise the old "ti,swap-xy" property (suggested by Rob Herring) 2015-11-06 16:14:53: This patch series improves the drivers for the tsc2007 and ads7846/tsc2046 touchscreen controllers which are e.g. used by the GTA04 OpenPandora and Pyra devices. New common bindings have been defined by commit b98abe52fa8e ("Input: add common DT binding for touchscreens"): 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.
