ldo7_reg, obviously ;)

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 at 48:palmas_pmic: failed to register 48070000.i2c:palmar

The patch I posted fixes this. Then for the HDMI see below.
I've kept it at 2V like we have in omap5-board-common.dtsi,
I wonder if it really should be 1.8V though for ldo7 in this
case?

Regards,

Tony
