It really seems to be ldo7, otherwise there's no HDMI output. I don't
have the schematics either.

But it seems we have at least two other regressions in Linux next that
prevent me from testing this properly:

1. On igepv5, I get this for the MMC regulator

ldo9: bypassed regulator has no supply!
ldo9: failed to get the current voltage(-517)
palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmar

I'm pretty sure it really is using the ldo9 for MMC just like
omap5-uevm.. Nishanth suggested it may use something else, but
why would it as ldo9 has a nice voltage range?

2. On both omap5-uevm and igepv5, NFSroot hangs

It seems that NFSroot boots to the point where PM runtime now
just shuts down some regulator affecting the USB connected
smsc Ethernet adapter?
