The vdd3p0's input should be from external USB VBUS directly, NOT

Shouldn't USB VBUS usually be 5V?  It doesn't seem to match 3.0V which is
suggested by vdd3p0 name.

PMIC's sw2, so remove the power supply assignment for vdd3p0.

Fixes: 93385546ba36 ("ARM: dts: imx6qdl-sabresd: Assign corresponding
power supply for LDOs")

Is it only a description correcting or is it fixing a real problem?  I'm trying to
understand it is a 5.5-rc material or can be applied for 5.6.

It is fixing a real problem about USB LDO voltage, that is why we noticed this issue.

Okay, please describe the problem a little bit in the commit log.  Also
squash the series into one patch, which is easier to be merged into -rc
as a fix.

My question above that USB VUBS is 5V which doesn't match 3.0V
suggested by vdd3p0 name remains unaddressed though.
