arm64: dts: qcom: c630: Expose LID events
The LID state can be read from GPIO 124 and the "tablet mode" from GPIO 95, expose these to the system using gpio-keys and mark the falling edge of the LID state as a wakeup-source - to wake the system from suspend. Tested-by: Steev Klimaszewski <steev@kali.org> Acked-by: Shawn Guo <shawn.guo@linaro.org> Link: https://lore.kernel.org/r/20201125060838.165576-1-bjorn.andersson@linaro.org Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
