Hi,
Fixed regulators are used to nicely model the regulators which aren't tied to any PMIC. But for some cases we use them to represent supplies when there is no support for the specific PMIC present in the kernel and they are turned on/configured by the bootloader (this is what happening here). And there is no use of declaring fixed regulators when there is no consumer. Even if you don't define these, the corresponding supplies in the board will always be in the same state configured by the bootloader. So I'd suggest you to remove this for now.
Checked the schematics and regulator name is the same for both eMMC and uSD Shall we keep uSD regulator sd_vcc to be consistent across ACTIONS platform?
Since I don't have the schematics to check, please make sure you name the regulators as mentioned in the schematics (this could vary from board to board, so don't just copy from others).
Sure, point noted. Thanks -Amit.
