I tested this patch on a board with an MT6363. Without it, vsram-cpum reads as enabled while its own enable bit is clear, because the driver reads the VS1 bit. With it, the four LDOs report their own enable bit, and vsram-cpum, which the board DT keeps always on, is now enabled at boot. With always-on dropped for a test, enabling and disabling vsram-cpum from a test consumer only changes its own enable bit, and VS1 stays on. I did not test the low power mode, nor disabling the other three LDOs: on my board they supply SoC I/O and analog rails. Tested-by: Alexandre Mergnat
