I cannot see any of the TFLASH_* regulators being linked to eMMC (they are only linked to the SD card slot, I also checked odroid-c2_rev0.2_20151218.pdf and odroid-c2_rev0.2_20171114.pdf). which page of the odroid-c2_rev0.2_20151218.pdf schematics shows how TFLASH_VDD is linked to eMMC? please note that I don't have an Odroid-C2 board myself (so I cannot test any of this).
