Kevin, Yixun,

I find odd that we are adding a regulator to SoC device tree file.
Those regulator are usually part of board file

Unless the regulator is actually inside the SoC, this is not the place for it.

Sorry for not catching this earlier.

You're right, I should've noticed this earlier also.

Yixun, can you resend this with the regulators in the board file please?

In the mean time, I've dropped this from v4.19/dt64 branch,

Nevermind, Jerome fixed this up already in a series of DT updates for
AXG, so I'll keep it as is.

Thanks Jerome!
