Add device tree nodes for two power regulators on the J721E SK board. vsys_5v0: A fixed regulator representing the 5V supply output from the LM61460 and vdd_sd_dv: A GPIO-controlled TLV71033 regulator.
J721E-SK schematics: https://www.ti.com/lit/zip/sprr438 Fixes: 1bfda92a3a36 ("arm64: dts: ti: Add support for J721E SK")
For me does not looks like a fix, you can adding missing nodes

Shouldn't be this pin be output to control regulator ?
