2021-10-02Input: ariel-pwrbutton - add SPI device ID tableMark Brown1-0/+7
Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI device ID table.

2020-12-10Input: add driver for power button on Dell Wyse 3020Lubomir Rintel1-0/+169
This adds support for the power button attached to the Embedded Controller on a Dell Wyse 3020 "Ariel" board. The Embedded Controller's SPI interface is actually capable sending and receiving the PS/2 keyboard and mouse protocol data, which looks like a good fit for a serio driver. Howerver, I don't know of any machines where this is actually used. My board only has a single power button and no way to connect an actual keyboard or a mouse. Using the atkbd driver with serio would be an overkill and would be inconvenient for the userspace. Therefore this driver registers an input device that is only capable of reporting the power button presses and releases.
