Well, I don't think it's too unreasonable especially now we've got the fixed helper stuff which slims it right down - it makes it clear there's a missing thing that might need to get filled in and makes it easier to use the same regulator for other devices. > > Just to be clear, here is the thread on the board-specific approach: > > https://lkml.org/lkml/2012/2/8/415 > We should use the real regulator if passed from board file. > And if no real regulator is passed, just use the dummy fixed regulator > in gpmc-smsc911x.c. Yes, it should definitely be conditional. > This patch I posted should fix the situation and allow adding the > real regulators to board-*.c files when they become known: > http://www.spinics.net/lists/linux-omap/msg66714.html That should be changed to pass in a boolean flag rather than a pointer to platform device - the board may not have direct access to the relevant regulator (eg, if it's part of a MFD) or the regulator may be on another bus like I2C (for simpler regulator only devices).
