The way it's implemented would have to be done in the BSP because it's different for every board. Also, we'd have to decide how to detect if the board supports it or not. Silent fail if it isn't and have another define `RTEMS_GPIO_HAS_LOW_POWER`. That or just keep it undefined if it doesn't exist. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1499#note_159797 You're receiving this email because of your account on gitlab.rtems.org.
