Hi Peng,

I built origin/master from commit 041bc24d867a today for an imx8mp
board and am running into errors that appear to be introduced by this
series:

Is there a driver I'm perhaps missing that is needed now or are there
some patches that come from a different unmerged tree needed?

Best Regards,

Tim
