Update the vin-supply of the TLV71033 regulator from LM5141 (vsys_3v3) to LM61460 (vsys_5v0) to match the schematics. Add a fixed regulator node for the LM61460 5V supply to support this change.

Looking at schematic page -3
USB PD Controller is giving input to LM61460 , LM5141(3V3), and TPS62177.
Could you please recheck this, vin-supply for 3v3 regulator
Thanks

Please ignore previous comment , I realized you are changing parent for tlv71033 not for vsys_3v3.
With that
