[PATCH 0/2] Add SW_MACHINE_COVER key

[Merlijn Wajer <merlijn@wizzup.org>]

this series adds the sw_machine_cover key, and changes the nokia n900 dts to
expose the key via gpio-keys.

before, this gpio was used as card detect gpio, causing the card not to show up
if the phone was booted without cover, see this thread on linux-omap:

    n900: remove mmc1 "safety feature"? (was: re: mmc0 on nokia n900 on linux 5.4.18)

since there is no realistic use for using this gpio as card detect, instead
expose it to userspace via gpio-keys. there are no event type for machine covers
yet, so add that first.

the key should be 1 when the cover is closed, and 0 when the cover is open.

starting the nokia n900 with the cover removed, putting the cover in place:

    event: time 1581684523.415296, type 5 (ev_sw), code 16 (?), value 1

removing the cover again, exposing mmc1 and the battery:

    event: time 1581684529.413706, type 5 (ev_sw), code 16 (?), value 0
