Thanks Neil.
Wake up sources are configured in BL301, no related to other parts of U-boot.
Hi, Nick
are these wake up sources (power key, IR, bluetooth) correctly configured?

Any wakeup source configured in bl301 code embeded in the FIP bootable binary should work.
Usually Bluetooth & IR are configured in addition to a power key, but the vendor u-boot source
should be checked to confirm.
