ldo7_reg should not work as regulator since it is set to 'disabled' state
in the omap5-board-common.dtsi and the state is not changed to 'okay'
this means that the ldo7_reg is not available to be used in the igep0050
DTS file.
ldo4_reg is used by all other OMAP5 boards and this is most likely the
correct regulator to use with hdmi.
The hdmi needs 1.8V, but the ldo7_reg, based on the dtsi is 2V only.

Tony,
I don't have access to the schematics, but I believe tha the ldo7_reg is not the
correct regulator to be used for hdmi.
If you have access and it is really ldo7_reg, then we should have this in the
omap5-igep0050.dts file:
&ldo5_reg {
status = "okay";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
};
Regards,
Peter
