From: Mikhail Kalashnikov <redacted> All devices based on the A523/A527/H728/T527 processors contain a G57 MC1 GPU. Enable the DT nodes for this GPU and specify a regulator that supplies power to the SoC's VDD_GPU pins. The other parameters are set in the SoC dtsi, so are board independent.
Checked the schematics of the three boards where those are available, and it's indeed DCDC2 there providing the voltage. For the X96QPro+, regulators.txt in debugs confirms this as well.
