There are several IOs in ESP32-P4 which are in "SD card IO" power domain.
There are several IOs in ESP32 SD card capable targets which are in "SD card IO" power domain.
Power has to be supplied to this power domain externally (from outside the chip) via one of the pins.
Based on the schematic, specify the LDO IO pin.
