* Input: fsl-imx25-tcq - fix module autoload when registered via OFJavier Martinez Canillas2016-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.

* Input: touchscreen: Add imx25 TCQ driverMarkus Pargmann2016-02-111-0/+596
This is a driver for the imx25 ADC/TSC module. It controls the touchscreen conversion queue and creates a touchscreen input device. The driver currently only supports 4 wire touchscreens. The driver uses a simple conversion queue of precharge, touch detection, X measurement, Y measurement, precharge and another touch detection. This driver uses the regmap from the parent to setup some touch specific settings in the core driver and setup a idle configuration with touch detection.
