This drivers/misc/cardreader business is a big confusion for my mind.

Is it really that fantastic that it needs to be a unique special case?

To me it looks like a drivers/mfd thing which should have separate
drivers/regulator/rts5228.c (LDOs)
drivers/clk/rts5228.c (clocks)
subdrivers.

See for example drivers/mfd/sta2x11-mfd.c thay spawns a few
devices off a PCI card.
