2021-06-18Input: add SparkFun Qwiic Joystick driverOleh Kravchenko3-0/+156
A simple analog joystick built on Low Power ATtiny85 Microcontroller. Directional movements are measured with two 10 kΩ potentiometers connected with a gimbal mechanism that separates the horizontal and vertical movements. This joystick also has a select button that is actuated when the joystick is pressed down. Input events polled over the I2C bus.

2020-06-09Input: adi - work around module name confictArnd Bergmann1-0/+1
Making module name conflicts a fatal error breaks sparc64 allmodconfig: Error log: error: the following would cause module name conflict: drivers/char/adi.ko drivers/input/joystick/adi.ko Renaming one of the modules would solve the problem, but then cause other problems because neither of them is automatically loaded and changing the name is likely to break any setup that relies on manually loading it by name. As there is probably no sparc64 system with this kind of ancient joystick attached, work around it by adding a Kconfig dependency that forbids them from both being modules. It is still possible to build the joystick driver if the sparc64 adi driver is built-in.
