[opensuse-factory] Wanted: Correct power-switch for ARM based Chromebook
Hi, just to be noted that the patch rules-add-lid-switch-of-ARM-based-Chromebook-as-a-power-sw.patch which includes the line SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="gpio-keys.8", TAG+="power-switch" in the 70-power-switch.rules can not be fully corect. This because the "gpio-keys.8" is much to general and may cause trouble with other keyboard layouts. Therefore I'd like to see the output of such a Chromebook of the command: udevadm info -a /dev/input/by-path/*kbd which may give the more specific name of the power button.

Alex? Guillaume? Can any of you provide the requested information for the Samsung Chromebook? Independent of the exact GPIO key, the term "ARM based Chromebook" in the subject and patch name seems to be rather broad given that there's the original Samsung Chromebook, plus the HP Chromebook 11, plus an Acer Chromebook based on Tegra, plus some based on Rockchip, etc. which likely all use different GPIO configurations.
