2019-05-30treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 149Thomas Gleixner
Based on 1 normalized pattern(s): licensed under the gpl 2 or later extracted by the scancode license scanner the SPDX license identifier GPL-2.0-or-later has been chosen to replace the boilerplate/reference in 82 file(s).

2010-04-13Input: add Analog Devices AD714x captouch input driverBryan Wu
AD7142 and AD7147 are integrated capacitance-to-digital converters (CDCs) with on-chip environmental calibration for use in systems requiring a novel user input method. The AD7142 and AD7147 can interface to external capacitance sensors implementing functions such as buttons, scrollwheels, sliders, touchpads and so on. The chips don't restrict the specific usage. Depending on the hardware connection, one special target board can include one or several these components. The platform_data for the device's "struct device" holds these information. The data-struct defined in head file descript the hardware feature of button/scrollwheel/slider/touchpad components on target boards, which need be filled in the arch/mach-/. As the result, the driver is independent of boards. It gets the components layout from the platform_data, registers related devices, fullfills the algorithms and state machines for these components and report related input events to up level.
