Buck and LDO binding name changes.
The binding names for the regulators have been changed to match the current
expectation from existing device tree source files.
This fix rectifies the disparity between what currently exists in some
.dts[i] board files and what is listed in this binding document. This
change re-aligns those differences and also brings the binding document
in-line with the expectations of the product datasheet from Dialog
Semiconductor.
Bucks and LDOs now follow the expected notation:
{ buck1, buck2, buck3, buck4 }
{ ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }

Hi Mark,
Several device tree source files use a regulator naming scheme different to
that found in the binding text document. Since those have been used
already, I would like ensure to the binding document follows those existing
DT file naming conventions.
Please refer to the files containing da9052/53 references:
- ./arch/arm/boot/dts/imx53-voipac-dmm-668.dtsi
- ./arch/arm/boot/dts/imx53-qsb.dts
Those board files use the naming convention:
{ buck1, buck2, buck3, buck4 }
{ ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }
Instead of the existing suggestion in the device tree binding file:
{ buck0, buck1, buck2, buck3 }
{ ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10, ldo11, ldo12, ldo13 }
The binding file regulator names (as it stands) does not reflect any
real-world uses I can find. This change would bring it in-line with
currect expectations from existing DTS files and make it similar enough to
the product datasheets to be "less confusing" than it currently is.
Regards,
Steve
