Hi, Looks like commit 39de2c4275a9 ("mfd: syscon: Make use of of_iomap") makes at least MMC PBIAS regulator stop working on omap3. That's probably because of_syscon_register uses the now unintialized struct resource res to set syscon_config.max_register. I have a strange deja vu feeling that we've been through this before :) See commit ca668f0edfae ("mfd: syscon: Set regmap max_register in of_syscon_register") Maybe we should add comments there instead?
