Hi, does reboot work for you with this patchset?
I have tested on 2 different IPQ5018 boards and they wont reboot,
I get the:
Requesting system reboot
[ 321.005977] qcom_scm firmware:scm: No available mechanism for setting
download mode
[ 321.006128] reboot: Restarting system
And then it just hangs there.
Regards,
Robert
