The SD card refuses to work because the regulator is turned off. Enable
it by default.

That's odd. Are you sure regulator is provided in SD card node? Is it
SDCC1 or SDCC3?
Best regards,
Krzysztof

I believe it's SDCC3. Unfortunately, I don't think this patch is the
solution either anymore. It was working with this patch consistently,
but now my phone just hangs on mounting the SD card like before. I've
tried a combination of GPT and MSDOS + vfat, ext2, and ext4. I'm not
sure what I'm doing wrong cause the SD card consistently works on the
downstream Linux kernel :(
Sorry for wasting your time
Thanks,
Rudraksha
