It is not described for the Orange Pi Zero2, so the core falls back to a dummy regulator and logs at boot: spi-nor spi0.0: supply vcc not found, using dummy regulator Per the Orange Pi Zero2 v1.3 schematic, the 2 MiB SPI NOR flash on SPI0 (port PC) is powered from the 3.3 V VCC-IO rail generated by ALDO1, which already supplies port PC here. Describe it.
