These are used in u-boot: grep -r regulator-init-microvolt

doc/device-tree-bindings/regulator/regulator.txt:-
regulator-init-microvolt: a init allowed Voltage value
doc/device-tree-bindings/regulator/regulator.txt:
regulator-init-microvolt = <1800000>;
drivers/power/regulator/pwm_regulator.c:        priv->init_voltage =
dev_read_u32_default(dev, "regulator-init-microvolt", -1);
drivers/power/regulator/regulator-uclass.c:     uc_pdata->init_uV =
dev_read_u32_default(dev, "regulator-init-microvolt",

U-Boot always tries to merge Linux devicetrees with minimal changes,
but I guess nobody ever tried to "upstream" that property?

In any case, in a lot of rockchip boards in the u-boot source,
I do see the regulator-init-microvolt in the *-u-boot.dtsi override file,
so it already seems to be agreed that this stuff is bootloader-specific.
[rk3399-pinebook-pro-u-boot.dtsi, and a number more]

So I guess, if nobody complains to loudly, I guess I'll merge this patch.

That's what I had in mind - when somebody next syncs these DTs to U-Boot 
and the properties disappear, that seems like unnecessary risk of 
breakage. Given that we know this property *does* have a use, surely the 
obvious correct course of action is to fix the binding?

Given that on the other hand we're merging entire DTs into the Linux 
tree purely to fix schema warnings in U-Boot, I think we could do with 
being a bit more logical and consistent here.

Thanks,
Robin.
