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.
