If anyone has any objections, please let me know. ------------------ From: Francesco Dolcini commit fbe94be09fa81343d623a86ec64a742759b669b3 upstream. LDO5 regulator is used to power the i.MX8MM NVCC_SD2 I/O supply, that is used for the SD2 card interface and also for some GPIOs. When the SD card interface is not enabled the regulator subsystem could turn off this supply, since it is not used anywhere else, however this will also remove the power to some other GPIOs, for example one I/O that is used to power the ethernet phy, leading to a non working ethernet interface.
