Add wakeup pinctrl state with PIN_WKUP_EN and mark the user button as a wakeup-source to allow the GPIO key to wake the system from suspend. Signed-off-by: Kendall Willis <redacted> --- Depends on series "Input: gpio-keys - support wakeup pinctrl state" [1]. This patch cannot be merged until series [1] has been.
