Something I forgot to mention is that this vmmc-supply is a DT hack
since the WLAN SDIO chip needs a WL_EN signal to be asserted as a part
of the chip power sequencing.

But there wasn't a DT binding to describe that so most boards use the
same hack which is to define a fake fixed-regulator with an enable
GPIO just to toggle that pin.

But now the MMC subsystem has support for power sequence providers and
the pwrseq-simple driver
(Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.txt) has
support for reset GPIOs so you may want to change that as well.

interesting. i wasn't aware of it.
but that's for a different time i guess :)

thanks,
Eliad.
