* dt-bindings: input: tm2-touchkey: convert to yamlStephan Gerhold2020-12-091-33/+0
| | | | | | | | | | | | | | | | Convert the device tree bindings for tm2-touchkey to the YAML format. While we're at it, clarify the descriptions a bit to make it clear that this driver can be used for many different MCUs that all implement a similar I2C protocol. Depending on the MCU the voltage requirements may be different, on some devices the controller uses 2.2V, 2.8V or even 3.3V for vcc-supply instead of 1.8V.

| * dt-bindings: remove 'interrupt-parent' from bindingsRob Herring2018-07-251-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | 'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

* | Input: tm2-touchkey - allow specifying custom keycodesJonathan Bakker2019-01-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Not all devices use the same keycodes in the same order, so add possibility to define keycodes for buttons present on actual hardware. If keycodes property is not present, we assume that device has at least MENU and BACK keys.

|/ | | | | | | | | | The touchkey on midas boards is almost identical. The only real difference is that it uses the same register for both keycode and base.

* Input: tm2-touchkey - add touchkey driver support for TM2Jaechul Lee2017-01-181-0/+27
This patch adds support for the TM2 touch key and led functionality. The driver interfaces with userspace through an input device and reports KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by "/sys/class/leds/tm2-touchkey/brightness".
