It is dedicated to eMMC device and can be turned off. Patch "mmc: sdhci: apply voltage range check only for non-fixed regulators" restored sdhci to working state after merging the regulator fix. However there are lots of error messages from sdhci driver: s3c-sdhci s3c-sdhci.0: could not set regulator OCR (-1)
The only remaining problem is sdhci driver operation with dummy regulator. Right now it simply fails to initialize if dummy regulator is enabled. Do you have any idea how to fix it properly?
