We have a peach-pi in our LAVA lab so I've tested it and
actually, it does fix the hang on v4.15-rc3:
https://lava.collabora.co.uk/scheduler/job/1019877
https://lava.collabora.co.uk/scheduler/job/1019878
I ran it twice and it booted both times. I also ran the same
boot tests with the same kernel but the dtb from v4.15-rc3
without the fix to double check and these failed:
https://lava.collabora.co.uk/scheduler/job/1019879
https://lava.collabora.co.uk/scheduler/job/1019880
Tested-by: Guillaume Tucker <guillaume.tucker@collabora.com>
Thanks for the fix!
Guillaume
