Never mind, I guess this is solved now.

There are already several device tree files using a naming scheme different to that found
in the binding text document. Since those have been used for real already, I will just follow
those existing DT file naming conventions instead.

./arch/arm/boot/dts/imx53-voipac-dmm-668.dtsi
./arch/arm/boot/dts/imx53-qsb.dts

Those board files files use the naming convention:
{ buck1, buck2, buck3, buck4 }
{ ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }

So, instead of the naming convention used in the existing binding text file (listed above)
I will send a patch to update that file to use with the existing usage already found in the
kernel board files.

Regards,
Steve
