Are you sure this shouldn't be the MFD?
I just looked at regulator_register() and saw that it does rdev->dev.parent = dev, so yes this has to be the MFD.
Do the regulators manage to get their supplies?
So, for now I thought it made sense to set the operating mode to normal on probe() but I'll change it to read from the hardware if that is better.
Yes, otherwise if the device is configured otherwise then when we change the configuration we may break something.
I guess I should check in the datasheet if a sane default operating mode for LDOs is expected when the chip is reseted or if this is left undefined and also if the bootloader already set this.
You can't do anything based on the particular bootloader you're using in your current system, this has to work in other systems. -------------- next part -------------- A non-text attachment was scrubbed...
