I do not find in my emailer 5/5 - I grab 0/5 for the answer.

Patch 4/5 is like a trick, but I am asking if the same solution can be used on other boards. The issue looks to me quite general, and if ldo-bypass must be set depends on if there is a capable PMIC.

What about to let this code become more general moving into imx-common ? Do you see any issue why we shouldn't ?

Best regards,
Stefano Babic
