Lephe dd564f094a keydev: add a keyboard device layer to abstract away globals ... The new keyboard device (keydev) interface implements the kernel's view of a keyboard providing input events. Its main role is to abstract all the globals of the KEYSC driver and getkey functions into a separate object: the "keyboard device". The device implements event transformations such as modifiers and repeats, instead of leaving them to getkey. While this can seem surprising at first, a real keyboard controller is responsible for repeats and modifier actions depend on the state of the keyboard which is only tracked in real-time. In this commit, getkey() has not changed yet apart from indirectly using the keydev interface with pollevent(). It will be changed soon to use event transforms in keydev_read(), and will be left in charge of providing repeat profiles, handling return-to-menu, backlight changes and timeouts, all of which are user convenience features.		2021-03-05 09:31:34 +01:00
