USB port regulators should be controlled by PHYs
so we remove always-on property and let PHYs manage the
regulator.

phy-supply isn't sconfugred for the TypeC port and now that we are
removing regulator-always-on, we need to fix the phy-supply
so the PHYs are able to turn power to type-c port.

Just to explain for me, what is supplying the "other" OTG port
	u2phy1_otg: otg-port {}

in u2phy1 ... this one is status okay, but does not have any phy
supply?

In RockPro64 there is only 1 USB-C OTG port and the other port
is a USB-3.0 port.
To be honest, I am not 100% sure how this all works, as I understand
the USB3.0 port is wired to the second TypeC Phy.

Maybe Dragan has more info on this.

Kind regards,
Shantur

I'll have it checked and tested in detail, of course, but I have to 
recover from this nasty flu first.  Unfortunately, it has rendeded me 
unable to even think straight.

just a small comment regarding timing. All regular development changes
need to be finished and in linux-next _before_ the merge-window opens.

As this is not a fix it will go to 6.9 anyway - hence no need to rush.

Thankfully, I'm feeling significantly better after more than two weeks 
of misery, and I hope to be able to work on this in the next few days.  
I'll do my best to have it done in the current merge window, together 
with a few new patches that I have planned to submit to the mailing 
list.

Hope you are feeling better.
Just to update, my patch has been dropped in u-boot in expectation of
it being fixed here.

Do you foresee it happening anytime soon?

Kind regards,

Yes, I saw that message on the U-Boot mailing list.  Frankly, that's the
usual way, i.e. having the DT issues fixed in the Linux kernel first, 
and
then synced back to U-Boot.

> Do you foresee it happening anytime soon?

Unfortunately, I've been unable to focus well enough to be able to work 
on
this, as a result of still recovering from the _nasty_ flu. :(  Though, 
I've
been also getting gradually better, thankfully, so while crossing all my
fingers and knocking on wood at the same time, :) I'd dare to say that 
I'm
expecting to be able to work on this in the next few days.

I apologize for the delays.  Bear with me, please! :)
