As per schematics add missing VDDAO_3V3 power supply to FLASH_VDD
regulator. Also add TFLASH_VDD_EN signal name to gpio pin.

Could you please add a link to the specific schematics you used to find
this usseu?

Your patch does not do this part.

Similarily to the other patch, can you explain in more detail (including
kernel boot logs) how the SD card is not working?

I just tested with latest mainline, and the MMC driver is detecting both
the eMMC and the SD card.

Ok lets discard this changes, I have tried many dts changes
but I do not know where is the problem or where I am going wrong.
