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 Merlijn Wajer (2): Input: add `SW_MACHINE_COVER` ARM: dts: n900: remove mmc1 card detect gpio arch/arm/boot/dts/omap3-n900.dts | 12 ++++++++---- include/linux/mod_devicetable.h | 2 +- include/uapi/linux/input-event-codes.h | 3 ++- 3 files changed, 11 insertions(+), 6 deletions(-)
