We do have eMMC present on Cubieboard 7 (both the versions of Cubieboard7), and the regulator name is similar to what is used in "s900-bubblegum-96.dts" .i.e. "vcc_3v1". But Since this patch doesn't enable eMMC, it does make sense to remove this "vcc_3v1" regulator and keep the other one. > > Also, another day tested it without having these regulators in , and > > still it seems to > > work.

Sure, I would do this. > What is the story with the other regulator? Is there a PMIC or a power > switch for the SD card? Or is the power supply actually hardwired? SD_VCC is connected to SWITCH/LDO which gets input from ATM2603C PMIC. This seems to be enabled by default ( in early bootloaders I guess). Thanks -Amit.
