I think it's better to give this a real node name.  The
"regulator_3_3v" will get dropped when you compile this into a binary
format (for shipping), so you're creating a node that's just called
"regulator".  If you had more than one fixed regulator like this it
just won't work.

I haven't seen any official guidelines, but I tend to use "regulator"
as a suffix and then put the schematic name.  Like:

  3_3v_regulator: 3-3-v-regulator

Not sure if there's a limit on a node cannot start with numeric value?
But if I change it to your suggestion, the DTC does not compile:

Error: arch/arm/boot/dts/socfpga_cyclone5_socdk.dts:41.16-17 syntax error
FATAL ERROR: Unable to parse input tree


But regulator_3_3v: 3-3-v-regulator   will work fine.
