I added vmmc-supply = <&vdd-3v3-sd>; in the sdhci node and it gave me the next error:

I saw this post
And also tried with vmmc-supply = <&vdd_3v3>; but it also gave me an error:
ERROR (phandle_references): Reference to non-existent node or label "vdd_3v3_sd"
ERROR: Input tree has errors, aborting (use -f to force output)

How do I set vmmc-supply to vdd-3v3-sd?
